Ready mixed concrete plant need powder, aggregates, water and additive, etc…
Concrete batching equipment aggregate including such as pebbles, gravel, coarse aggregate and fine aggregate such as sand and gravel.
The role of the aggregate in concrete is as a skeleton or filling loose granular materials, and as skeleton and supporting role in the building. In the use of concrete mixer batching plant equipment for commercial concrete production, mode selection and matching of raw materials is very important.
When rock strength at the same, the gravel surface area is greater than the pebble, and its adhesion with cement mortar are better than pebbles. So often in the construction of the gravel as coarse aggregate commodity concrete configuration needed.
But the specific ratio to control in the reasonable scope, is the volume of concrete with higher stability and durability, and reduce the number of net cement slurry adverse effects such as fever, dry shrinkage.
The choice of batching plant fine aggregate should first choose coarse, middle river sand as well. Fine fine, particle concentration, under the same water cement ratio, sand mixing cement used in the commercial concrete to a lot more than the use of coarse sand and compressive strength will decline, and frost resistance and abrasion resistance will be more bad.
The selection of concrete plant aggregate requires first of all should have sufficient strength, dense texture; And then out to clean enough, harmful substances and impurities, through relevant standards. Then there is the aggregate of particles to the appropriate level, appearance shape also influence the work-ability of mixture and the strength of the concrete, and surface coarse aggregate mixing of commodity concrete work-ability is poorer, high strength; And smooth surface of the aggregate and cement bonding is poorer, mixing of good inexorability of concrete, but slightly lower strength.
