水利水电工程中大体积砼的温度控制，通常选择低热水泥、掺入粉煤灰减少水泥用量等措施。而采用外加剂降低水泥水化热则为一种全新方法。本试验结合小浪底工程对江西南昌蛟溪无机盐厂JC505-FW低水化热防水剂进行检验。
Water conservancy and hydropower projects in the mass concrete temperature control, usually select low-heat cement, fly ash to reduce the amount of cement and other measures. The use of additives to reduce the hydration of cement is a new method. This experiment combined with Xiaolangdi project on Jiangxi Nanchang Jiao River inorganic salt plant JC505-FW low heat of hydration agent for testing.
