Grouting material for composite structure and fabricated building joint and preparation method thereof
The invention relates to a grouting material for composite structure and prefabricated building node pouring. The grouting material is prepared from, by mass, 30%-40% of cement, 10%-20% of an early-strength mineral admixture, 25%-45% of quartz sand, 5%-15% of a superfine mineral admixture, 0.5%-5% of a composite additive and 5%-10% of fiber, and the superfine mineral admixture is two or three of microbeads, silica fume and nano-silicon dioxide. The composite additive comprises an expanding agent, a retarder, a defoaming agent, a reinforcing agent and a water reducing agent; the fiber is a mixture of steel fibers and organic fibers. The invention also discloses a preparation method of the grouting material, and the method comprises the following steps: mixing the components of the groutingmaterial into a dry mixture, packing and packaging, and the preparation method is simple. The grouting material has the advantages of micro-expansion, high filling property, ultrahigh strength, high ductility and high vibration resistance.
本发明涉及一种用于组合结构及装配式建筑节点浇筑的灌浆料，按质量百分比计，包含：水泥30％～40％，早强型矿物掺合料10％～20％，石英砂25％～45％，超细矿物掺合料5％～15％，复合外加剂0.5％～5％，纤维5％～10％，其中，超细矿物掺合料为微珠、微硅粉和纳米二氧化硅中的两种或三种；复合外加剂为膨胀剂、缓凝剂、消泡剂、增强剂和减水剂；纤维为钢纤维和有机纤维混合物。还公开了上述灌浆料的制备方法，包括：将灌浆料各组分混合成干混料并包装打包，制备方法简单。上述灌浆料具有微膨胀、高充填性、超高强度、高延性和高抗振性能。
