Abstract

Correction 12/7/2017 Production process of ready-mixed concrete with water for washing milling In this case, the water must have the pH value. Chloride content, sulfate content (SO4) and suspension content for only one value. And there is a process Production from preparation of concrete mixers with clean interior and moist internal surfaces, weighing stone and cement into the concrete mixer. Then turn the machine at a speed of 35 rpm to mix the rocks. And sand and cement are homogeneously mixed in a mixer. When the cement, sand and stone are well mixed together, add two-thirds of clean water. When the added water is mixed well with sand, stone and cement. Begin adding a concrete admixture (admixture) by mixing it with clean water mixed with the concrete. Remaining water and milling wash and turn on the concrete mixer to make the added solution compatible with the concrete mixture.
