Ceramsite concrete for pumping and preparation method thereof
The invention discloses ceramsite concrete for pumping. The ceramsite concrete is prepared from cement, natural sand, mineral powder, fly ash ceramsite, clear water, fly ash, an additive, slag powder, a pumping agent, waterborne polyurethane emulsion, free radical copolymerization modified water-soluble resin, an organic siloxane defoaming agent and a composite foam stabilizer. According to the invention, the pumping pressure loss is effectively reduced, large-area floating of ceramsite due to vibration is controlled, and holes caused by air which cannot be pumped out due to low fluidity are solved.
本发明公开了一种用于泵送的陶粒混凝土，包括水泥、天然砂、矿粉、粉煤灰陶粒、清水、份粉煤灰、外加剂、矿渣粉、泵送剂、水性聚氨酯乳液、自由基共聚改性型水溶树脂、有机硅氧烷消泡剂和复合型稳泡剂。通过本发明有效的降低了泵压损失，控制陶粒因振捣大面积上浮，解决低流动性带来的无法拍出的空气造成的孔洞。
