Sleeve grouting material for steel bar connection
The invention relates to a sleeve grouting material for steel bar connection. The sleeve grouting material is prepared from the following raw materials in parts by mass: cement, silica fume, quartz sand, a polycarboxylic acid water reducing agent, naphthalene water reducing agent expansion and water. The expanding agent is prepared from the following raw materials in parts by mass: metal compoundparticles, acrylic fibers and metal elementary substances. According to the sleeve grouting material for steel bar connection, the fracture resistance, the pressure resistance and the static slurry fluidity of the sleeve grouting material for steel bar connection can be effectively improved, and the number of air holes in the grouting material is reduced.
本发明涉及一种钢筋连接用套筒灌浆料，包括质量份数如下的原料：水泥、硅灰、石英砂、聚羧酸减水剂、萘系减水剂膨胀和水；其中，所述膨胀剂包括质量份数如下的原料：金属化合物颗粒、丙烯酸纤维和金属单质。所述发明可以有效地提高钢筋连接用套筒灌浆料的抗折抗压能力、静浆流动度，并减少灌浆料中气孔的数量。
