蓄热法 本实用新型主要用于温度小于10℃、结构较厚的工程中。它是：原材料（水、砂、石）进行加热，使混凝土在搅拌、运输和灌溉，还保留了相当的热量，以使水泥水化热的更快，并加强混凝土保温，使温度下降到0度，新浇注的混凝土冻结足够的能力之前。这种方法简单，施工成本不多，但要注意内部保温，避免墙角和外露的表面的冷，并延长养护龄期。 防冻剂  在小于10℃的温度下，混凝土外加剂中的化学剂可以降低水的凝固点，使混凝土在负温状态下仍处于液态状态，水化作用得以继续，从而使混凝土强度不断增长。目前常用的氧化钙、氯化钠等单一防冻剂和亚硝酸钠和氯化钠复合防冻剂。 thermos method The utility model is mainly used for the engineering with a temperature less than 10 DEG C and a thick structure. It is: raw materials (water, sand, stone) for heating, make concrete in mixing, transportation and irrigation, also retains a considerable amount of heat faster, so that the heat of hydration of cement, and strengthen concrete insulation, the temperature dropped to 0 degrees before the new pouring concrete freezing enough. This method is simple, the construction cost is not much, but should pay attention to the internal insulation, to avoid the corner and exposed surface of the cold, and extend the curing age. Antifreeze At temperatures less than 10 DEG C, the freezing point of chemical agent in concrete admixture can reduce water, make the concrete in negative temperature state is still in the liquid state, hydration continues, thus increasing the strength of concrete. At present commonly used calcium oxide, sodium chloride and other single antifreeze and sodium nitrite and sodium chloride compound antifreeze. 合肥泡沫混凝土官方网站：http://www.ahzjcl.com/ 最新内容：
