Preparation method of machine-made sand reactive powder concrete
The invention discloses a preparation method of machine-made sand reactive powder concrete, and belongs to the technical field of novel RPC materials. Short steel fibers accounting for 0.5-2% of the volume of the concrete and long steel fibers accounting for 0-1.5% of the volume of the concrete are doped into the concrete, and cement, fly ash, silica fume, mineral powder, machine-made sand, water and a water reducing agent with the mass ratio of 0.62: 0.20: 0.13: 0.05: 0.7: 0.18: 0.015 are used as basic materials, so that the mechanical property of the prepared machine-made sand reactive powder concrete is enhanced.
本发明公开了一种机制砂活性粉末混凝土的制备方法，属于新型RPC材料技术领域。本发明在混凝土中掺入混凝土体积0.5‑2％的短钢纤维和0‑1.5％的长钢纤维，并以质量比为0.62∶0.20∶0.13∶0.05∶0.7∶0.18∶0.015的水泥、粉煤灰、硅灰、矿粉、机制砂、水和减水剂成分作为基础材料，使得制备的机制砂活性粉末混凝土力学性能增强。
