First of all, the concrete mix proportion should ensure that the concrete has good working performance, such as pumpability, large fluidity, self compacting, etc. To meet the engineering structure strength, durability and other special design requirements. In the mix proportion design of concrete, the concrete admixtures such as superplasticizer should be actively and reasonably applied to reduce the water consumption of concrete, reduce the water binder ratio and improve the strength of concrete. Adding high quality fly ash, mineral powder and other admixtures in concrete to replace part of cement and part of fine aggregate can significantly improve the compactness of concrete, increase the protection of reinforcement and reduce the economic cost of concrete under the condition of ensuring the strength grade and working performance of concrete.
Secondly, the management of raw materials of the full-automatic feeding mixer should be strengthened, and the sand and stone yards should have good drainage facilities to avoid water accumulation at the bottom. Moisture proof and rainproof measures shall be taken for cement and fly ash silos. Sand and stone materials shall be stacked separately according to varieties and specifications to avoid mixing. All kinds of materials shall be clearly marked, especially the cement, fly ash silo, additive storage bin and other feeding ports shall be stamped with marks, and managed by special personnel, so as to prevent wrong feeding or pollution.
Full automatic feeding mixer truck can speed up the construction progress, reduce environmental pollution, improve construction conditions, improve project quality and save material cost. However, the quality control of fully automatic feeding mixer truck is also an important point.
The way to control the quality of full-automatic feeding mixer truck is the above. I hope all the major projects built now can be completed with quality and quantity guaranteed.
The engine selected for the full-automatic feeding mixing truck must be of sufficient horsepower, because it needs to drive the power take-off, hydraulic oil pump and reducer to operate the mixing tank. On the other hand, we have to provide power to the chassis. We can't do without enough horsepower.
The gearbox of Shaan tooth fast is recommended here, and its workshop and gearbox logistics vehicles can be seen everywhere in China; Small concrete mixer engine horsepower can be slightly smaller, because the work intensity is not so big, enough on the line, but not too small, too small to buy the hand is not fuel saving, delay.
