Low-hydration-heat high-strength grouting material
The invention discloses a grouting material with low hydration heat and high strength. The grouting material is prepared from the following components in parts by weight: 320 to 450 parts of high belite cement, 40 to 80 parts of superfine slag powder, 35 to 50 parts of fly ash aluminosilicate fine microbeads, 10 to 30 parts of metakaolin, 10 to 20 parts of silica fume, 420 to 650 parts of basalt machine-made sand, 0.1 to 0.3 part of an expanding agent, 2.0 to 5.0 parts of a water reducing agent, 0.1 to 0.2 part of a suspending agent, 0.1 to 0.5 part of a de-foaming agent and 80 to 95 parts of water. The high-strength grouting material prepared in the invention has the advantages of good fluidity, slight expansion, good durability, centralized early hydration, low heat release and no shrinkage cracking.
本申请公开了一种低水化热高强灌浆材料，包括如下重量份的组分：320～450份的高贝利特水泥、40～80份的矿渣微粉、35～50份的粉煤灰硅铝酸盐精细微珠、10～30份的偏高岭土、10～20份的微硅粉、420～650份的玄武岩机制砂、0.1～0.3份的膨胀剂、2.0～5.0份的减水剂、0.1～0.2份的悬浮剂、0.1～0.5份的消泡剂和80～95份的水。本申请制备的高强灌浆材料流动性好、微膨胀、耐久性好，早期水化集中放热低、灌浆材料无收缩开裂。
