Homemade Concrete Mixers

For the occasional concrete job, like re-pouring a sidewalk slab or filling a post hole, it might not be financially feasible to rent a concrete mixer. There are homemade alternatives to mix concrete.

Homemade Cement Paddle
  • When mixing small batches of concrete, you can mix the concrete in a five-gallon bucket using a heavy duty electric drill and a cement paddle. Construct a cement paddle from a 2-foot piece of round bar, 7/16-inch in diameter and a 1-1/2 coils of a car spring. Weld a piece of 1/2-inch flat bar to one end of the rod and then weld the spring to the bar. The other end of the rod connects into the bit end of the electric drill.
Warnings About Drill Speed
  • If your electric drill's motor speed is too slow it will have to fight to move the heavy concrete and the motor will burn out. If you are using an industrial drill, keep the speed below 650 rpm to avoid air bubbles in the mixture.
Concrete Mixing Drum
  • If you will be mixing large batches of concrete, you can re-purpose a washer drum. Attach angle brackets to the center tumbler to create mixing blades. Fill the holes on the washer drum with auto body putty. Mount the washer drum at an angle on a steel pipe frame. Rotate the drum by hand so that the blades scoop the concrete and drop it from the top of the drum.

Concrete batching plant cement

As one of the concrete batching plant cement concrete in the most important raw material, how it and other materials the ratio of science is a science, scientific computing the amount of cement, not only to produce high-quality concrete, but also to reduce raw material andhuman and material resources, reduce production costs of concrete fundamentally, so that enterprises in market competition invincible! Today, we focus on what the amount of cement concrete batching plant:

Relationship (1) the amount of cement and transport resistance and concrete pump volumetric efficiencyCement content should be appropriate. If the amount of cement shortage, pumping volume efficiency decreases significantly increase transport resistance, and this concrete water retention is poor, easy bleeding, segregation and clogging; if excessive cement, concrete viscosity will be too large, increasing resistance delivery Great, but little change in pumping volume efficiency.(2) the amount of cement and aggregates varieties relationshipIn the same diameter, graded gravel aggregate and gravel aggregate compared to a large amount of cement concrete gravel. For fine aggregate, the use of artificial broken sand more than natural sand with cement.Relations (3) the amount of cement and duct diameter, duct lengthThe smaller the diameter, the longer the pipe, the flow of concrete requirements, lubricity, higher water retention, so the amount of cement should be increased.These are concrete batching plant in the amount of cement, and more practical engineering, may be the ratio of the amount of other raw materials, according to the different circumstances of the ingredients and reasonable control on the amount of cement, can produce a suitable concrete.

Something About Asphalt Solution

We are the distributor of the revolutionary asphalt recycling technology invented by Angelo Benedetti industries. With our exclusive agreement for Latin America, now you can access this technology with local support.

We can say that the asphalt recycling is reuse from existing asphalt layers that have been in service. Aging happens on materials that have already lost their properties.
The advantages of this technique provides not only environmental benefits but also economic gains, as it helps the reduced use of raw materials, in this case oil and bituminous products.
Recycling techniques.
This kind of methods rely on the reuse of defective materials. Together with these materials aged, you can add additional elements (rejuvenating agents, new asphalt mix, etc..). These techniques can be divided in different types, which we briefly below:
Recycled “in situ” hot. Reuses the entire firm materials extracted from aged by treatment with heating that takes place in the same location of the work.
The asphalt Solution is heated by a burner and milled a given thickness. This material is typically mixed with chemical rejuvenating and remix. Finally, the new mixture is spread and compacted by conventional methods.

Frequency building hoist FAQ

1. The building hoist is one of the major high-rise construction crane equipment most commonly used in building construction, the construction site is a major hazard in security checks and safety management as a key should be the focus. Past accidents and bloody lesson is profound, only in October 2008 - November, on a spate of domestic building hoist 2 from major accidents, killing 12 people and 18 people were killed and direct and indirect losses exception huge, huge irreparable damage to multiple families. In recent years, construction accidents tended to increase gradually beyond the coal industry, in addition to a traffic accident become the second largest security incidents outside the industry. Strict inspection, scientific management, prevention is the construction site construction crane safety management key, we need serious discussion and analysis.
2 construction lifts Checkpoints
2.1 Part-site inspection entity
2.1.1 base, base, fence
⑴ check whether basic parts of water, if there is evidence of uneven or sink.
⑵ mounted on one floor of the elevator, you must check the basement roof support systems and computing programs and inspection data base (including covert acceptance).
⑶ check the base, fence grounding system meets the requirements, whether the grounding resistance less than or equal 4Ω.
⑷ cage and the counterweight buffer (spring) is complete and effective.
⑸ pick tight end of the cage surrounding undamaged and height of not less than 1.8m.
With the development of science and technology, frequency control in building hoist to get more and more widely used. Frequency has a smooth start and stop the process, reduce the mechanical impact and increase occupant comfort, improve service life, but also can adjust the speed by varying the frequency of power supply, save energy, improve efficiency, but in the course of Frequency Control System It will be interference, often caused by building hoist accidents happen.
Building hoist inverter system circuit consists of two parts of the main circuit and control circuit. The main circuit consists of two parts rectifier, inverter circuit; a control circuit consists of a microprocessor, PAW trigger, PWM current controller and current feedback and other components.
Sources of interference building hoist inverter circuit block diagram of frequency control system are: overvoltage, undervoltage, instantaneous power failure inductive interference; inductive interference surge currents; inductive interference peak voltage pulse; when the weather since fog inductive interference sense currents; radio signal interference.
Building hoist inverter system after interference can cause your system is running out of control, causing the motor is running faster or slower, running up and down the cage unstable speed; the control malfunction occurs stop button and emergency stop button does not work, the motor can not stop such phenomena may cause loss of control or by falling construction elevator, causing accidents.

You never played "swing tower crane"

Tower crane swings a lot of people have played, is a very exciting game. Six Flags Over Texas theme park in this exciting game to the peak. It built the world's tallest tower crane swings the crane 400 feet high (about 121.9 meters), you can achieve 35 miles per hour visitors (about 56.3 km) speed in the air speeding dream.

The crane uses a classic swing rotation flight mode, after the visitors will start at high altitude speed of 56.3 kilometers per hour, with a diameter of about 124 feet (about 37.8 meters) circle flight. The tower crane swings both as a group, can accommodate 24 visitors.If you still dare to utter daring visitors rose to the top of the crane at the eyes, then he enjoy the exciting experience, it is also possible to see them all, not only the beauty of the panoramic view of the city of Arlington, but also overlooking the style of Dallas and Fort Worth.The park director Steve Martindale, said: "The completion of the world's tallest tower crane swing so we are very excited, it will give tourists the most unique flying experience." A total of seven in the US theme parks Similar flight swing rotation, but compared with the latest build of this, other competitive advantage is clearly insufficient.The second high crane swing in Georgia, height of only 242 feet (about 73.8 meters). General crane swing rotational speed of 43 miles per hour (about 69.2 km), but due to the large volume of this newly built, for security, so it's flight speed is 35 miles per hour (about a 56.3 km ).

2 Beach-Ready Braid Tutorials

During the summer months, we are constantly by the water. If you’re heading to the beach, pool or lake, these two hairstyles have been tried and tested to stay put for hours!
Surf-Safe French Braided Side Chignon
You can create this wet-hair style after you’ve been in the water as a chic way to pull your hair back whether you’re lounging on the sand or hitting the surf.
Step 1. Wet your hair and spray with leave in-conditioner (I like to use It’s a Ten). This is a great way to keep your hair detangled while strengthening it at the same time.
Step 2. Start a French braid at the top left side of your head and continue the braid toward the right.

Step 3. Continue to braid all the way through until you reach the ends of your hair.
Step 4. Twist the braid around into a bun and secure with an elastic hairband. If you have thick hair, use a second hairband to ensure the style is secure.
This is so tight and secure that it’s even surf safe! Ready for the next tutorial?
Double Twist Beach Braid
Step 1. Spray leave-in conditioner and distribute evenly through hair using your fingers (see above). Split your hair down the middle and braid one side. Secure with a hairband.
Step 2. Braid down the other side. Take out the hairbands and hold the ends of both braids.
Step 3. Twist the braids around each other tightly.
Step 4. When you get close to the ends of your hair, pull out three sections to braid the rest of the way. Secure with a hairband.
That’s all it takes! You can still have a fun, stylish ‘do while you beach bum! (Surf, volleyball, swim, and maybeee even water ski proof ;))

Focusing on remediation concrete mixer


Yesterday, the Wuhan public security departments announced the 2014 concrete transport unit vehicle illegal rankings, Wuhan Shing Logistics Company Limited (are), although only have three concrete mixers, but since the number of illegal vehicles on average up to 61 onwards, ranking one. With immediate effect, Wuhan City, the traffic control department will undertake concrete mixers traffic violations special rectification action within the city.

Currently, the city a total of 3251 sets concrete transport vehicles. 2014 total input electronic eye traffic violations since 6845, car traffic violations occurred from 2.1. With immediate effect, Wuhan will be concrete mixing sand and other raw materials, vehicles and transport vehicles leak spill, ran a red light, speeding, overloading, high, involving a license card-related fatigue driving and other traffic violations as the focus of regulation of seized concrete mixer traffic violations, strict penalties, do not eliminate the violations are not released, the parties are not subject to education is not released, affiliated companies do not take corrective measures are not released, effectively regulate road traffic order.

Driving Tips concrete mixer run-in period

What is the period of transition it? "Running-in period" means new car "unconventional" to travel for some time, let the engine, each rotation drive member chassis of running smoothly. New car factory, since the machining accuracy and other reasons, the period starts running, moving parts, each part of the vehicle not running, therefore, it must be used with caution, otherwise it will aggravate damage components for the future and security.

Running under the normal conditions of cement tanker 5000 road, although concrete mixer at the factory cold running process, but in order to maintain the best condition after the mechanical system and extend the service life of 1500 km before the recommendations must be careful driving your concrete truck mixer maintenance phases.


So the early speed can not be used because of high speed enables the engine and transmission components of the load increases. The speed should be controlled within a predetermined range. In the 1000-1500 km, can gradually increase the engine speed and the vehicle speed to the highest default rate. Not allowed to use long or high gear with the first gear; in each gear, do not make the speed limit is reached, each gear per hour speed to be controlled within the range of the top three-quarters speed, generally: 1 gear 25 km, 40 km 2 block 3 block 60 km, four-speed 90 km, 5-speed 100 km. We must not drill at this time driving skills, rush rushing. In addition to the speed limit outside the driver's injuries must strictly enforce rules, it is necessary to avoid full-throttle; the second is to maintain the normal operating temperature of the engine. At the same time the new car should Lawton, load factor should be less than 90%, and choose a flat road.

There is a need to check the transmission, front and rear drive axles, drive shafts and other if there is leakage. At the same time, braking capacity and tightness, seal Check the brake system. 200-500 kilometers before, thanks to new friction brake pads have not yet reached 100% of the braking effect, the brake should advance. Taking into account the tire friction force is not enough, when the brake foot than a little hard point under normal circumstances, this also applies to people who are just new tires or new owners of the brake pedal. In addition, it is preferable to check the entire vehicle exposed bolt and nut fastening.

Concrete pump suddenly sounding great fault repair method

Analysis: In the casting process, Tuobeng suddenly issued a rhythmic "giggle" sound, pressure pulse is large, carefully argued hear, determine the sounds from the hydraulic pump. If Tuobeng factory, life is not reached, according to normal use, will not damage the pump element, you can judge it may be due to pump into the air and cause this noise.

Troubleshooting: the main hydraulic concrete pump exhaust treatment for the above situation, if the problem persists, you can remove the main hydraulic pump disintegration test machine, such as found in the shoe and the plunger is "separation", you can replace main hydraulic pump, hydraulic oil and filter, and clean the hydraulic system. Try the opportunity to discover Tuobeng back to normal, the analysis can know that Tuobeng main hydraulic pump shoe and the plunger is premature failure, mainly because of serious pollution of hydraulic oil.
