Early high-strength self-leveling bridge pier column reinforcing mortar material
A disclosed early-strength self-leveling bridge pier column reinforcing mortar material is prepared from the following components in parts by weight: 69 to 71 parts of quick-hardening sulphoaluminatecement, 6 to 8 parts of ordinary Portland cement, 18 parts of fly ash, 5 to 8 parts of silica fume, 2 parts of gypsum, 120 parts of quartz sand, 0.30 to 0.55 part of water reducing agent, 0.01 part ofdefoaming agent, 1 part of expanding agent, 0.005 part of SPA, 0.035 to 0.04 part of adelayed coagulant, and 2 parts of glue powder. A finished product/water equals 25/3.5-25/3.8. The material of invention has the characteristics of high early strength, stable increase of later strength, good fluidity, high bonding strength and the like, and has excellent construction performance.
本发明公开了一种早高强自流平桥梁墩柱加固砂浆材料，按重量份计包括如下组分：快硬硫铝酸盐水泥69～71份，普通硅酸盐水泥6～8份，粉煤灰18份，硅灰5～8份，石膏2份，石英砂120份，减水剂0.30～0.55份，消泡剂0.01份，膨胀剂1份，SPA 0.005份，缓凝剂0.035～0.04份，胶粉2份，成品/水=25/3.5～25/3.8。本发明具有早期强度高、后期强度稳定增长、流动性好、粘结强度高等特点，具有优良的施工性能。
