Abstract

------January 29, 2018------(OCR) Page 1 of 1. Summary of the Invention: The ready-mixed concrete production process for overlaying aims to mix the raw materials for concrete production for waterproofing applications according to a specific procedure using a high-performance mixer. It begins with preparing a clean concrete mixer. Weigh the aggregate (maximum size 6.0 mm) and cement and place them in the mixer. Then, the mixer is turned on 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 2.35 liters per cubic meter. The mixer is then turned on again to allow the admixture to be thoroughly mixed with the concrete mixture for 30 seconds. The mixing process is then complete. ------------ Revised June 2, 2017: The ready-mixed concrete production process for overlaying aims to mix the raw materials for concrete production for waterproofing applications according to a specific procedure using a high-performance mixer.
