Concrete has been used in one or another form since Romans constructed the Appian way. The transit mixer came into existence in the 20th century.
People refer to concrete trucks as cement mixers in the construction industry that come in different sizes, types, and configurations for handling the multiple tasks set regularly.
It needs to fill up; so many roles mean the equipment is changing shape, form, and dynamic as per the requirement of people. The working of concrete trucks and the purpose behind the work they do is an excellent combination of old and new technology. You are not going to see the old cement mixer again.
There is a difference between a cement mixer and a concrete truck. Cement is the blend of finely ground minerals and goes with the name ‘portland’ generically.
Concrete is the generic term for an aggregate mix, usually gravel, cement, stone, or water. A cement truck combines the three ingredients in a mixer, whether that mixer is driving down the road or stationary, that binds aggregate altogether, creating concrete.
Concrete Truck’s working routine
Concrete trucks use mainly designed paddles for stirring around wet and dry ingredients in the barrel. Corkscrew-shaped augers and fins replace the initial mixing apparatus faster. ‘
Augers combine ingredients of concrete and control the position of the material in the barrel. Drills will move towards the mixer’s back section during transport to include material. The operator reverses the direction of the drill to pour the mixed concrete out of the barrel.
Cement trucks can pour mixed cement out of the barrel and in the prepared worksite area using a long hose and chute. The chute delivery method works well for ground-level pours, and the truck operator locates the chute above the worksite and reverses the drum to eject material on the ground. Hose delivery enables operators to send concrete.
After delivering concrete, operators should clean the barrel to remove concrete that hardens along the barrel’s walls. Pre-treatment chemicals and acid baths applicable after returning from each job help eliminate much of the concrete from the barrel.
A small amount of concrete still stays permanently to the inner surface of the barrel despite some cleaning efforts. As a result, it is mandatory to remove hardened concrete deposits mechanically by using a hammer.
Manufacturers of Cement trucks are striving continuously to improve the function of those heavy-duty construction vehicles by using computer-controlled systems. Operators using trucks developed in the past few years enjoy the efficiency and ease of using computer control to adjust the concrete pouring procedure.
From the mixing of concrete to delivery out of the barrel, the entire working process of the concrete truck is discussed in brief. You can go through its future advancements that are under research. A machine allows truck operators to pour and mix concrete without keeping the engine running during the procedure.
