Abstract

Revised 30/08/2017. The process for producing ready-mixed concrete for small diameter bored piles aims to mix the raw materials for concrete production according to a specific procedure using a specialized mixer. Step 1: Prepare a clean concrete mixer. Weigh the aggregate (maximum size 19.0 mm) and cement and place them in the mixer. Then, turn on the mixer to mix the aggregate, sand, and cement thoroughly. Once the mixture is well mixed, add all the water. After the water is well mixed with the sand, aggregate, and cement, begin adding concrete admixture at a rate of 1.65 liters per cubic meter. Turn on the mixer again to allow the admixture to thoroughly mix with the concrete mixture for 30 seconds. This completes the mixing process. .................................................................................................................................................
