Organic-inorganic hybrid internal curing agent as well as preparation method and application thereof
The invention relates to an organic-inorganic hybrid internal curing agent as well as a preparation method and application thereof. The preparation method comprises the following steps: preparing a gel suspension from raw materials of the organic-inorganic hybrid internal curing agent, reacting to obtain organic-inorganic hybrid gel, dehydrating, and grinding to obtain the organic-inorganic hybrid internal curing agent, based on 100% of the organic-inorganic hybrid internal curing agent, the dry weight of the composite silicon-calcium inorganic gel is 1-2%; the dry weight of the composite silicon-calcium inorganic gel is 100%, and the composite silicon-calcium inorganic gel comprises 1%-3% of acrylamide homopolymer or copolymer. The organic-inorganic hybrid internal curing agent provided by the invention has a good shrinkage reducing effect by adding a small amount of the organic-inorganic hybrid internal curing agent provided by the invention, and does not cause adverse effects on the flowing effect during concrete mixing and the strength after hardening.
本发明是关于一种有机无机杂化内养护剂及其制备方法和应用，其制备方法为：将有机无机杂化内养护剂原料制成凝胶悬浊液，反应得到有机无机杂化凝胶，脱水、研磨后得到有机无机杂化内养护剂；以有机无机杂化内养护剂为100％，所述复合硅钙无机凝胶的干重为1％～2％；以复合硅钙无机凝胶干重为100％，其组分包括1％～3％的丙烯酰胺均聚物或共聚物。本发明提供的有机无机杂化内养护剂少量添加即可具有良好的减缩效果，且不会对混凝土拌和时的流动效果与硬化后的强度造成不良影响。
