High-fluidity high-strength mineral mixture mortar and preparation method thereof
The invention relates to the technical field of cement mortar, and particularly discloses high-fluidity high-strength mineral mixture mortar, which is prepared from the following raw materials in parts by weight: 27 to 36 parts of Portland cement, 2 to 8 parts of slag, 1 to 4 parts of metakaolin, 9 to 11 parts of water, 60 parts of graded sand, 0.08 to 0.09 part of glass fiber and 0.7 to 0.8 part of auxiliaries. According to the invention, the composite Portland cement, the slag, the metakaolin and the mortar hardening product are converted from hydrated calcium silicate (C-S-H) to hydrated calcium aluminosilicate (C-A-S-H), and the graded sand is matched, so that the fluidity of the mineral mixture mortar material can reach more than 300mm, and the strength is remarkably improved. Compared with a traditional high-fluidity and high-strength cement-based material adopting multiple chemical additives to reduce the water cement ratio, the method provided by the invention has the advantages that by regulating and controlling the hardening reaction product, the cost is lower, the process is simple, the cracking risk does not exist after hardening, the industrial waste slag is efficiently utilized, the environment is effectively protected, and the application prospect is wide. The application of industrial production of cement products is facilitated.
本发明涉及水泥砂浆技术领域，具体公开一种高流动度高强度矿物混合料砂浆，包括以下重量份的原料：硅酸盐水泥27～36份，矿渣2～8份，偏高岭土1～4份，水9‑11份，级配砂60份，玻璃纤维0.08～0.09份，助剂0.7～0.8份。本发明通过复合硅酸盐水泥、矿渣、偏高岭土，砂浆硬化产物由水化硅酸钙(C‑S‑H)向水化硅铝酸钙(C‑A‑S‑H)转化，再搭配级配砂，在保证矿物混合料砂浆材料流动度能够达到300mm以上，同时显著提升强度。相较于传统的高流动度高强度水泥基材料采用多种化学助剂降低水灰比的方法，本发明方法通过调控硬化反应产物，成本更低，工艺简单，且硬化后不存在开裂风险，高效利用了工业废弃物矿渣，有效的保护了环境，有利于水泥制品工业化生产的应用。
