Composite solid nano-based early strength agent and preparation method thereof
The invention discloses a composite solid nano-based early strength agent and a preparation method thereof, and the composite solid nano-based early strength agent is formed by uniformly mixing the following three substances in percentage by mass: 80-90 parts of a solid early strength type polycarboxylate superplasticizer, 5-15 parts of mesoporous nano silicon dioxide, and 5-10 parts of mesoporous nano aluminum oxide. The solid early-strength polycarboxylate superplasticizer, the mesoporous nano-silica and the mesoporous nano-aluminum oxide are separately put into a ball mill to be fully ground and mixed, so that the composite solid nano-based early-strength agent is prepared, the prepared solid early-strength agent can obviously improve the early strength of concrete, and meanwhile, the later strength is enhanced. According to the composite solid nano-based early strength agent and the preparation method thereof, the performance is improved, the reinforcing effect is good, and storage and long-distance transportation are convenient.
本发明公开了一种复合型固体纳米基早强剂及其制备方法，其由以下质量百分比的三种物质混合均匀形成：固体早强型聚羧酸减水剂80‑90份，介孔纳米二氧化硅5‑15份，介孔纳米氧化铝5‑10份，将固体早强型聚羧酸减水剂、介孔纳米二氧化硅和介孔纳米氧化铝分别放到球磨机中进行充分的打磨混合，从而制得复合型固体纳米基早强剂，本发明制备的固体早强剂能显著提高混凝土的早期强度，同时增强后期强度，该复合型固体纳米基早强剂及其制备方法，性能提升，增强效果好，便于储存和长途运输。
