Summary of the Invention: The process for producing sulfate-resistant 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. The process begins with preparing a clean concrete mixer. Weigh the largest aggregate (19.0 mm), sand, and cement and place them in the mixer. Then, start the mixer to mix the aggregate, sand, and cement thoroughly. Once the mixture is well combined, add all the water needed for mixing. After the water is well mixed with the sand, aggregate, and cement, add concrete admixture at a rate of 1.45 liters per cubic meter. Start the mixer again and allow the admixture to mix thoroughly with the concrete mixture for 30 seconds. The mixing process is then complete. ------------ Edited June 2, 2017.

The purpose of this ready-mixed sulfate-resistant small-diameter bored pile concrete production process is to mix the raw materials according to a specific procedure using a high-performance mixer. The process begins with preparing a clean concrete mixer. Weighing the aggregate (maximum size 19.0 mm), sand, and cement are placed into the mixer. The mixer is then started to mix the aggregate, sand, and cement thoroughly. The mixture is homogeneous in the mixer. Once the ingredients are well mixed, add all the water.
