Quick-hardening early-strength cement-based grouting material for stabilizing bottom plate of bridge support and preparation method of quick-hardening early-strength cement-based grouting material
The invention discloses a quick-hardening early-strength cement-based grouting material for stabilizing a bottom plate of a bridge support, which comprises the following components in parts by weight: 100-200 parts of ordinary Portland cement, 10-20 parts of sulphoaluminate cement, 6-12 parts of a CSA expanding agent, 20-30 parts of silica fume, 0.3-0.5 part of a polycarboxylate water reducing agent, 30-40 parts of granulated blast furnace slag, 10-20 parts of uncalcined coal gangue and 20-30 parts of fly ash microspheres. 5 to 7 parts of anhydrous sodium metasilicate, 0.2 to 0.5 part of a defoaming agent, 0.2 to 0.5 part of a thickening agent and 60 to 100 parts of water. The invention also discloses a preparation method of the cement-based grouting material. The cement-based grouting material provided by the invention is good in fluidity, high in early strength, capable of being rapidly cured, excellent in mechanical property, simple in preparation method and low in preparation cost.
本发明公开了用于桥梁支座底板稳固的快硬早强水泥基灌浆材料，以重量份计，包括以下组分：普通硅酸盐水泥100‑200份，硫铝酸盐水泥10‑20份，CSA膨胀剂6‑12份，硅灰20‑30份，聚羧酸盐减水剂0.3‑0.5份，粒化高炉矿渣30‑40份，未煅烧煤矸石10‑20份，粉煤灰微珠20‑30份，无水偏硅酸钠5‑7份，消泡剂0.2‑0.5份，增稠剂0.2‑0.5份，水60‑100份。本发明还公开了上述水泥基灌浆材料的制备方法。本发明提供的水泥基灌浆材料流动性好，早期强度高，能够快速固化，力学性能优异，且制备方法简单，制备成本低。
