Hydration heat inhibitor for concrete as well as preparation method and use method of hydration heat inhibitor
The invention relates to the field of concrete additives, and particularly discloses a hydration heat inhibitor for concrete as well as a preparation method and a use method of the hydration heat inhibitor. The hydration heat inhibitor for concrete is prepared from starch hydrolysate and an additive, the weight ratio of the starch hydrolysate to the additive is 100: (1-3), the starch hydrolysate is prepared from the following raw materials: starch, water, hydrolase and a purifying agent, the weight ratio of the starch to the water to the hydrolase is 100: (250-500): (0.02-0.08), and the purifying agent is prepared from the following raw materials: starch, water and hydrolase. The volume ratio of the water to the purifying agent is 4: 1. The hydration heat inhibitor for concrete can be used for concrete engineering, and has the advantages of effectively controlling the hydration heat release speed of cement and reducing the influence on the strength and setting time of concrete.
本申请涉及混凝土添加剂领域，具体公开了一种混凝土用水化热抑制剂及其制备方法及使用方法。混凝土用水化热抑制剂由淀粉水解物和添加剂制备而成，所述淀粉水解物与添加剂二者重量之比为100:(1～3)，所述淀粉水解物由包括以下原料制备而成：淀粉、水、水解酶和提纯剂，所述淀粉、水和水解酶三者重量之比为100:(250～500):(0.02～0.08)，所述水和提纯剂二者体积之比为4:1。本申请的混凝土用水化热抑制剂可用于混凝土工程，其具有有效控制水泥水化放热速度，减少对混凝土强度和凝结时间影响的优点。
