TH12704C3 - Production process for large-diameter ready-mixed concrete - Google Patents

Abstract

Revised 24/11/59. The process of producing ready-mixed concrete for large-diameter bored piles begins with preparing the concrete mixer, ensuring the interior is clean and the inner surface is moist (not completely dry), and the aggregate (stone and sand) is saturated with water and has a surface dryness. Weigh the stone and cement and add them to the concrete mixer. Then, start the mixer to mix the stone, sand, and cement thoroughly. Once the mixture is well mixed, weigh the fly ash and add all the water used for mixing. When the added water is well mixed with the sand, stone, and cement, begin adding the concrete admixture while starting the mixer to allow the admixture to be thoroughly mixed with the concrete mixture. This completes the mixing process. ...................................................................................................................................................... The process of producing ready-mixed concrete for large-diameter bored piles begins with preparing the concrete mixer, ensuring the interior is clean and the inner surface is moist (not completely dry), and the aggregate (stone and sand) is saturated with water and has a surface dryness. Weigh the stone and cement and add them to the concrete mixer. Then, start the mixer at a certain speed. To mix the aggregate (stone, sand, and cement) thoroughly in a mixer, once the cement, sand, and stone are well mixed, weigh the fly ash and add all the water. While adding the water, operate the concrete mixer to ensure the water is thoroughly mixed with the sand and cement mixture. Once the water is well mixed with the sand, stone, and cement, begin adding the concrete admixture while continuing to operate the mixer. This completes the mixing process.
