Bush grouting material for fabricated concrete engineering, and preparation method thereof
The invention belongs to the technical field of building materials. The problems that the existing bush grouting material is poor in strength and prone to agglomeration are solved. The invention provides a bush grouting material for fabricated concrete engineering, and a preparation method thereof. The bush grouting material is prepared from the following components in parts by weight: 90 to 100 parts of cement, 40 to 55 parts of modified mineral powder, 1 to 2 parts of fine sand, 3 parts of a water reducing agent, 3 parts of a retarder, 2 parts of a defoaming agent, 1 part of an expanding agent, 3 to 5.5 parts of graphene oxide, 1 to 3 parts of an auxiliary agent and 15 to 25 parts of water. The preparation method comprises: uniformly mixing cement, modified mineral powder and fine sand to obtain a first material; uniformly mixing thewater reducing agent, theretarder and theexpanding agent to obtain a second material; uniformly mixing graphene oxide and theauxiliary agent to obtain athird material; and adding the second material and the third material into the first material, slowly adding thedefoaming agent and water, wherein the temperature of the defoaming agent is -5 DEG C, and the temperature of the water is 0-3 DEG C. The bush grouting material prepared through the method has the advantages of being good in strength and not prone to agglomeration.
本发明属于建筑材料技术领域，为了解决目前的套筒灌浆料强度差和易团聚的问题，本发明提供了一种装配式混凝土工程用套筒灌浆料及制备方法，其中制备方法包括：套筒灌浆料以重量份计，包括以下组分：水泥90‑100份，改性矿物粉料40‑55份，细砂1‑2份，减水剂3份，缓凝剂3份，消泡剂2份，膨胀剂1份，氧化石墨烯：3‑5.5份，助剂1‑3份，水15‑25份；将水泥、改性矿物粉料和细砂混匀得到第一物料；将减水剂、缓凝剂和膨胀剂混匀得到第二物料；将氧化石墨烯和助剂混匀得到第三物料；将第二物料和第三物料加入第一物料中，缓慢加入消泡剂和水，消泡剂的温度为‑5℃，水的温度为0‑3℃。本发明方法制备的套筒灌浆料具有强度好和不易团聚的优点。
