------August 30, 2018------(OCR) Page 1 of 1. Summary of the Invention: The ready-mixed concrete production process for prestressed reinforced concrete and waterproofing applications aims to mix the raw materials for prestressed reinforced concrete and waterproofing applications according to a specific procedure using a specialized mixer. The process begins with preparing a clean concrete mixer. The aggregate (maximum size 19.0 mm) and cement are weighed and placed into the mixer. The mixer is then started to mix the aggregate, sand, and cement thoroughly. Once the mixture is well combined, all the water is added. After the water is thoroughly mixed with the sand, aggregate, and cement, concrete admixture is added at a rate of 2.93 liters per cubic meter. The mixer is then started for 1 minute to allow the admixture to fully mix with the concrete mixture. The mixing process is then complete. ------------ Edited August 30, 2017.
