TH12663A3 - Production process of ready-mixed concrete in cold storage - Google Patents

Abstract

Edit 5/10/16 The process of producing ready-mixed concrete for cold storage has started from preparing a concrete mixer that Weigh the rock with the maximum size of 19.0 and 6.0 mm and add it to the concrete mixer. Then turn on the machine at 18 revolutions per minute to mix the stone and sand and cement homogeneously in the mixer for 1 minute, then weigh and add the fly ash, turn on the mixer continuously for 30 seconds. After mixing well, add three-fourths of the total water used. However, while adding water, turn on the concrete mixer so that The added water is well combined for 30 seconds. When the added water is well mixed with sand, stone and cement, a strong concrete admixture is started. By mixing with water, the remaining concrete mix and turn on the mixer. Concrete for the added solution to be well combined with the concrete mixture for 15 seconds and add the cold room specific solution, stir the concrete for 30 seconds to finish. .................................................. .................................................. ................................................. The production process of ready-mixed concrete for use in cold storage starts from preparing a concrete mixer. Weigh the rock with the maximum size of 19.0 and 6.0 mm and add it to the concrete mixer. The machine is then turned on at 18 rpm to homogeneous mixes of stone and sand and cement in the mixer for 1 minute, then weigh and add fly ash. With the mixer continuously on for 30 seconds when mixing Get along well Therefore add 3-fourths of the water used to mix all However, while adding water, turn on the concrete mixer. To allow the added water to mix well for 30 seconds, when the added water is well mixed with sand, stone and cement, a strong concrete admixture is started. By mixing with water, the remaining concrete mixture is ready to turn on the concrete mixer so that the added solution mixes well with the concrete mixture for 15 seconds and add a cold room specific solution. Continue to spin the concrete for 30 seconds to complete the cold room ready-mixed concrete.
