Concrete functional admixture as well as preparation method and application thereof
The invention discloses a functional admixture for improving concrete performance and a preparation method and application thereof. The functional admixture is prepared from the following raw materials in parts by mass: 80 to 120 parts of silicate solution, 5 to 15 parts of gas-phase nano silicon dioxide, 0.5 to 1.5 parts of fatty acid salt surfactant, 0.05 to 0.16 part of hydrated calcium silicate guide liquid, 0.2 to 0.6 part of fluosilicate, 0.1 to 0.4 part of air entraining agent, 0.1 to 0.3 part of defoaming agent, 0.5 to 1.0 part of early strength agent and 0.1 to 0.9 part of retarder. The invention further provides concrete which contains the functional admixture, is high in compactness and has a crack self-repairing function.
本发明公开了一种改善混凝土性能的功能外加剂及其制备方法和应用。所述功能外加剂由以下质量份数原料制成：硅酸盐溶液80‑120份，气相纳米二氧化硅5‑15份，脂肪酸盐类表面活性剂0.5‑1.5份，水化硅酸钙引导液0.05‑0.16份，氟硅酸盐0.2‑0.6份，引气剂0.1‑0.4份，消泡剂0.1‑0.3份，早强剂0.5‑1.0份，缓凝剂0.1‑0.9份。本发明还提供一种包括该功能外加剂的密实性高、具有裂纹自修复功能的混凝土。
