Concrete micro-expansion reinforcing agent, preparation method thereof, concrete and application thereof
The invention provides a concrete micro-expansion reinforcing agent, a preparation method thereof, concrete and application thereof, and the reinforcing agent comprises the following raw materials inpercentage by mass based on the mass of the concrete micro-expansion reinforcing agent: 59.5%-89.7% of quick-hardening sulphoaluminate cement, 10%-40% of anhydrite and 0.3%-0.5% of nano calcium silicate hydrate whisker. The concrete micro-expansion reinforcing agent is prepared by taking high-temperature calcined minerals and natural minerals as main components and compounding a silicate cement mineral activation functional component and a hydration promoting component, and is a concrete performance reinforcing material capable of optimizing cement hydration. The cement hydration degree is improved, the cement hydration product proportion is adjusted, the cement hydration product crystallization configuration is improved, admixture redispersion and hydration are promoted, the effects of shrinkage reduction, compaction, reinforcement, crack resistance, waterproofness and the like are achieved, the compactness, early strength and later strength of concrete can be effectively improved, and the durability of the concrete is obviously improved.
本发明提出了一种混凝土微膨胀增强剂及其制备方法、混凝土及其应用，基于所述混凝土微膨胀增强剂的质量计，所述增强剂中包括如下质量百分含量的原料：快硬硫铝酸盐水泥59.5％‑89.7％，硬石膏10％‑40％和纳米水化硅酸钙晶须0.3％‑0.5％。本发明的混凝土微膨胀增强剂，以高温煅烧矿物和天然矿物为主要成分，复合硅酸盐水泥矿物活化功能组分、水化促进组分而成，是一种可以优化水泥水化的混凝土性能增强材料。通过提高水泥水化程度、调节水泥水化产物比例、改善水泥水化产物结晶构型、促进掺合料再分散和水化，起到减缩、密实、增强、抗裂、防水等作用，能有效提高混凝土的密实度、早期和后期强度，明显改善混凝土的耐久性。
