Sprayable impact-resistant flexible protective concrete for side slope
The invention discloses sprayable slope impact-resistant flexible protective concrete, and relates to the field of building materials, the sprayable slope impact-resistant flexible protective concrete is prepared from the following raw material components by weight: 40-48 parts of water, 100-120 parts of cement, 23-27 parts of fly ash, 311-173 parts of limestone gravel, 186-223 parts of river sand, 14-16 parts of modified rubber particles, 0.5-1 part of a water reducer, and 0.1-0.3% by volume of polyvinyl alcohol fiber. Wherein the modified rubber particles are obtained after modification treatment is conducted through a self-made modifier and have excellent cohesiveness with a cement matrix and good dispersity in the cement matrix, and the modified rubber particles and the polyvinyl alcohol fibers act together, so that the performance of the cement-based composite material is improved, and the service life of the cement-based composite material is prolonged. The sprayed concrete has high impact resistance, large deformation performance and good slump retaining performance.
本发明公开了一种可喷射的边坡抗冲击柔性防护混凝土，涉及建筑材料领域，由以下重量份的原料组分制成：水40‑48份、水泥100‑120份、粉煤灰23‑27份、石灰岩碎石311‑173份、河砂186‑223份、改性橡胶颗粒14‑16份、减水剂0.5‑1份、0.1％‑0.3％体积掺量的聚乙烯醇纤维；其中改性橡胶颗粒是经由自制改性剂进行改性处理后得到的，具有优异的与水泥基体的粘结性，和较好的在水泥基体中的分散性，通过本发明提供的改性橡胶颗粒与聚乙烯醇纤维共同作用，使喷射混凝土具有高抗冲击性能、大变形性能和较好的保坍性能。
