Abstract

------30/08/2561------(OCR) Page 1 of 1 Summary of Invention: A process for producing sulfate-resistant ready-mixed concrete using cement, fly ash, and specific concrete admixtures mixed in specific proportions as the main raw materials. The process begins with preparing a clean concrete mixer. Weigh the largest aggregate sizes (6.0 and 19.0 mm) and cement and place them in the mixer. Then, turn on the mixer to mix the aggregate, sand, and cement thoroughly for 1 minute. Continue weighing and mixing the fly ash in the mixer. Once the cement, sand, and aggregate are well mixed, add 2/3 of the total amount of water needed for mixing. While adding the water, keep the mixer running to ensure the water is thoroughly mixed with the sand and cement mixture. Once the water is well mixed with the sand, aggregate, and cement, begin adding the concrete admixture, mixing it with the remaining water while turning on the mixer. The concrete is mixed to ensure the added admixtures are well integrated with the concrete mixture, resulting in sulfate-resistant ready-mixed concrete. ------------ Revised 30/8/60 The production process of sulfate-resistant ready-mixed concrete involves mixing cement, fly ash, and specific concrete admixtures in specific proportions. The process begins with preparing a clean concrete mixer. Weigh the largest aggregate (6.0 and 19.0 mm) and cement and add them to the mixer for 1 minute.
