Silica mortar for concrete and preparation method thereof
The invention discloses silica mortar for concrete. The silica mortar comprises the following raw materials in parts by weight: 30-50 parts of silica fume, 50-70 parts of water, 0.6-5 parts of a dispersing agent, 0.6-2.5 parts of a stabilizer, 0.05-0.2 part of a thickening agent and 0.1-0.5 part of a defoaming agent, wherein the pH value of the silica mortar is adjusted to be 2-4 by a pH regulator. The silica fume is used as a main raw material, the composition of the dense silica fume is regulated and controlled, the composite dispersing agent, the stabilizer, the thickening agent and the defoaming agent are combined, and the pH value of the slurry is regulated by using the organic acid; the uniform and stable silica mortar is prepared through comprehensive action of various means, the utilization efficiency of silica fume particles can be greatly improved, the particle size of the silica fume particles is effectively reduced, the reaction activity of silica fume is improved, and the working performance, mechanical performance, durability and the like of silica fume concrete are improved; a new thought can be provided for efficient application of the silica fume.
本发明公开了一种混凝土用硅灰浆，各原料及其所占重量份数包括：硅灰30～50份，水50～70份，分散剂0.6～5份，稳定剂0.6～2.5份，增稠剂0.05～0.2，消泡剂0.1～0.5份，pH调节剂调节硅灰浆pH值为2～4。本发明以硅灰为主要原料，对加密硅灰组成进行调控，并结合复合分散剂及稳定剂、增稠剂、消泡剂，并利用有机酸调节浆液的pH值；多种手段综合作用，制备出均匀稳定的硅灰浆，可大幅提升硅灰颗粒的利用效率，有效降低硅灰颗粒粒径，提升硅灰反应活性，改善硅灰混凝土工作性能、力学性能和耐久性能等；可为硅灰的高效应用提供一条新思路。
