Green superfine high-performance composite admixture as well as preparation method and application thereof
The invention discloses a green superfine high-performance composite admixture as well as a preparation method and application thereof, the admixture comprises a first additive, a second additive, a third additive, silica fume, mineral powder, lime and gypsum, and the third additive is used for filling cement gaps and improving adhesive force. According to the green superfine high-performance composite admixture, the preparation method and the process that monomer molecules are connected through free radical reaction to form a high-molecular compound by applying polymerization reaction of natural fibers, hydrogen peroxide is added into concrete to react with iron ions in the concrete to generate iron peroxide, and oxygen is released; sodium hydroxide is added to accelerate decomposition of steel bar oxides and repair of the concrete surface, so that the effect of treating concrete corrosion is achieved, sodium hydroxide is added to react with silicate in the concrete to generate calcium silicate gel, so that the strength and durability of the concrete are improved, and in addition, sodium hydroxide can accelerate solidification of the concrete and shorten the pouring and curing time.
本发明公开了一种绿色超细高性能复合掺和料及制备方法和应用，所述掺合料中包含有第一添加物、第二添加物、第三添加物、硅灰、矿粉、石灰和石膏，其中第三添加物用于填充水泥缝隙以及提高粘合力。该绿色超细高性能复合掺和料及制备方法和应用天然纤维的聚合反应通过自由基反应将单体分子连接起来形成高分子化合物的过程，过氧化氢添加在混凝土中与混凝土中的铁离子反应生成过氧化铁，并释放出氧气，加速钢筋氧化物的分解和混凝土表面的修复，从而达到治理混凝土腐蚀的效果，同时氢氧化钠添加与混凝土中的硅酸盐反应，生成硅酸钙胶凝体，从而提高混凝土的强度和耐久性，此外，氢氧化钠还能加速混凝土的凝固,缩短浇注和养护时间。
