Automatic mixer truck can speed up construction progress, reduce environmental pollution, improve construction conditions, improve project quality and save material cost. However, the quality control of automatic mixer is also indispensable. So how should we control the concrete quality of automatic mixer truck?
The concrete mix proportion shall ensure that the concrete has good working performance, such as pumpability, high fluidity, self compactness, etc. Meet the strength, durability and other special design requirements of engineering structures. In the mix proportion design, concrete admixtures such as water reducing agent should be actively and reasonably applied to reduce the water consumption of concrete, reduce the water binder ratio and improve the strength of concrete.
Add an appropriate amount of high-quality fly ash, mineral powder and other admixtures into the concrete to replace some cement and some fine aggregate. Under the requirements of ensuring the strength level and working performance of concrete, it can significantly improve the compactness of concrete and increase the reinforcement of reinforcement. Protection, while reducing the economic cost of concrete.
The management of raw materials of automatic mixer truck should be strengthened, and the sand and gravel yard should have good drainage facilities to avoid ponding at the bottom. Cement, fly ash and other fly ash silos shall be provided with moisture-proof and rainproof measures. Sand and stone materials shall be stacked separately according to varieties and specifications to avoid mixing. All materials shall be clearly marked, especially the feed inlets of cement, fly ash silo and admixture storage silo, which shall be managed by a specially assigned person to prevent wrong materials or pollution.
In addition, the engine selected for the full-automatic mixer must have sufficient horsepower, because it must drive the power take-off, hydraulic oil pump and reducer to operate the mixing tank. On the other hand, it is necessary to provide power to the chassis, and insufficient horsepower is unacceptable.
The quality control method of automatic mixer truck is the above. I hope all major projects can be completed with quality and quantity guaranteed. For more relevant content, you can follow our website www.zkzsljbc.com Com for consultation!
