Elasticity reducing agent for sprayed concrete and preparation method of elasticity reducing agent
The invention discloses a elasticity reducing agent for sprayed concrete and a preparation method of the elasticity reducing agent. The elasticity reducing agent is prepared from the following raw materials in percentage by mass: 15%-30% of a quick-setting component, 2%-5% of a tackifying component, 10%-15% of a reinforcing component, 2%-5% of an anti-freezing component, 1%-4% of a stabilizer and the balance of water, the tackifying component is a composition of polyvinylpyrrolidone and modified carboxymethyl cellulose. The prepared elasticity reducing agent for the sprayed concrete has the advantages of being good in sprayability, high in hour strength, good in freezing resistance and stability and the like, can improve the working performance of the sprayed concrete, reduce the mixing amount of an accelerator and remarkably reduce the rebound rate of the sprayed concrete, and has good economic benefits.
本发明公开了一种喷射混凝土用减弹剂及其制备方法，由如下质量百分比的原料组成：速凝组份15%‑30%、增粘组份2%‑5%、增强组份10%‑15%、抗冻组份2%‑5%、稳定剂1%‑4%，其余为水；所述增粘组份为聚乙烯吡咯烷酮与改性羧甲基纤维素的组合物。本发明的制备的喷射混凝土用减弹剂，具有可喷性好、小时强度高、抗冻及稳定性好等优点，可改善喷射混凝土工作性能，减少速凝剂掺量并显著降低喷射混凝土回弹率，具有良好经济效益。
