Cement curing-free agent and preparation method thereof
The invention belongs to the technical field of cement, and particularly relates to a cement curing-free agent and a preparation method thereof.The preparation method comprises the steps that porous silicon dioxide is taken and subjected to amination modification, and modified silicon dioxide is obtained; preparing a calcium silicate seed crystal; then compounding the modified silicon dioxide and the calcium silicate seed crystal with polycarboxylic acid ether together to obtain a complex; and performing carbon dioxide adsorption on the complex, and mixing with an early strength material to obtain the health-preserving-free agent. The cement curing-free agent disclosed by the invention can be used for improving the strength of cement, promoting hydration and obviously shortening the curing time.
本发明属于水泥技术领域，具体涉及一种水泥免养生剂及其制备方法，取多孔二氧化硅，将多孔二氧化硅进行氨基化改性，得到改性二氧化硅；制备硅酸钙晶种；然后将改性二氧化硅与硅酸钙晶种一同与聚羧酸醚复合，得到复合体；将复合体进行二氧化碳吸附后与早强材料混合，得到免养生剂。本发明的水泥免养生剂可以提高水泥的强度，促进水化，明显缩短养生时间。
