混凝土中的游离水,孔隙水是造成混凝土冻害的祸根。但适量的水又是水泥水化必不可少的条件。采取化学与机械方法压缩游离水含量,并使之转化为结晶水、凝胶水、微毛细水。通过 CAS 活性载体在低、负温下的起始反应,激发水泥矿物的水化,以提高混凝土的早期强度,促进混凝土抗冻结构的形成。 The free water in the concrete, pore water is the cause of the frost damage of concrete. However, the proper amount of water is an indispensable condition for cement hydration. Chemical and mechanical methods are used to compress the free water content and convert it into crystal water, gel water, and microcapillary water. Through the initial reaction of the CAS active carrier at low and negative temperatures, the hydration of cement minerals is stimulated to increase the early strength of the concrete and promote the formation of the antifreeze structure of the concrete.
