High-strength and low-elasticity hydraulic anti-impact and anti-abrasion concrete and preparation method thereof
The invention discloses high-strength and low-elasticity hydraulic anti-impact and anti-abrasion concrete. The concrete comprises 270-310 kg/m<3> of cement, 170-200 kg/m<3> of superfine mineral powder, 1100-1300 kg/m<3> of broken stone, 460-500 kg/m<3> of river sand, 50-70 kg/m<3> of modified rubber powder, 100-120 kg/m<3> of a high-molecular polymer emulsion, 9-12 kg/m<3> of a water reducing agent and 70-100 kg/m<3> of water. The superfine mineral powder, the modified rubber powder and the high-molecular polymer emulsion are introduced into hydraulic concrete, so the hydraulic concrete has excellent small-angle cutting resistance and large-angle impact resistance while the mechanical property is guaranteed, effective unification of high strength, low elasticity, wear resistance and impactresistance is achieved, and the use performance and durability of the hydraulic concrete are effectively guaranteed; and the related preparation method is simple, low in cost and suitable for popularization and application.
本发明公开了一种高强低弹水工抗冲磨混凝土，各组分及其用量为：水泥270～310kg/m、超细矿粉170～200kg/m、碎石1100～1300kg/m、河砂460～500kg/m、改性橡胶粉50～70kg/m、高分子聚合物乳液100～120kg/m、减水剂9～12kg/m、水70～100kg/m。本发明通过在水工混凝土中引入超细矿粉、改性橡胶粉和高分子聚合物乳液，在保证力学性能的同时，可兼具优异的抗小角度切削和大角度冲击的性能，实现高强、低弹、耐磨和抗冲击性能的有效统一，有效保障水工混凝土的使用性能和耐久性能；且涉及的制备方法简单、成本较低，适合推广应用。
