High-performance cement-based early-strength grouting material and preparation method thereof
The invention discloses a high-performance cement-based early-strength grouting material and a preparation method thereof.The high-performance cement-based early-strength grouting material comprises quartz sand and micro-silica fume and further comprises P.C 42.5 composite Portland cement, 42.5 fast-hardening sulphoaluminate cement and a PCA-I type mother liquor polycarboxylic acid high-efficiency water reducer, the preparation method comprises the following steps that 1, the quartz sand is firstly taken and put into a high-speed pulverizer to be pulverized, and then the high-performance cement-based early-strength grouting material is obtained; the preparation method comprises the following steps: respectively grinding quartz sand to 26-40 meshes, 40-70 meshes and 70-110 meshes, taking P.C 42.5 composite Portland cement, then taking 42.5 rapid hardening sulphoaluminate cement and taking micro-silica fume, and grinding to 1500 meshes; and step 2, adding the components according to the weight ratio into a mortar stirring pot at one time, stirring, filling the grouting material into a triple test mold with the size of 40 * 40 * 160mm after stirring, and naturally curing for 3 days, 7 days and 28 days at the ambient temperature respectively. According to the high-performance cement-based early-strength grouting material and the preparation method thereof, the strength of the prepared cement-based early-strength grouting material is quickly improved, and the fluidity of the cement-based early-strength grouting material is good.
本发明公开了一种高性能水泥基早强灌浆料及其制备方法，包括：石英砂、微硅灰，还包括：P·C 42.5复合硅酸盐水泥，42.5快硬性硫铝酸盐水泥和PCA‑I型母液聚羧酸高效减水剂，其制备方法包括以下步骤：步骤1：先取石英砂放入高速粉磨机中粉磨，使石英砂分别磨至26‑40目、40‑70目和70‑110目，取P·C 42.5复合硅酸盐水泥，再取42.5快硬性硫铝酸盐水泥，取微硅灰磨至1500目；步骤2：将各组重量比的分一次加入砂浆搅拌锅中搅拌，搅拌完成后将灌浆料装入40×40×160mm三联试模中，在环境温度中自然养护分别养护3天、7天和28天。该高性能水泥基早强灌浆料及其制备方法，对制备而成的水泥基早强灌浆料的强度提升快，且水泥基早强灌浆料的流动性好。
