Preparation method of high-ductility cement-based composite material
The invention discloses a preparation method of a high-ductility cement-based composite material, the high-ductility cement-based composite material comprises fly ash, cement, sand, water, a water reducing agent and PVA fiber, the fly ash is 380kg/m < 2 >, the cement is 480kg/m < 2 >, the sand is 1150kg/m, the water is 150kg/m, the water reducing agent is 1.5% and the PVA fiber is 0.5-1.5%, after a cementing material is uniformly stirred, the water reducing agent is placed in the water to be uniformly stirred, then the water reducing agent and a cementing mixture are fully stirred to be in a plastic flow state, and the high-ductility cement-based composite material is prepared. The high-ductility cement-based composite material provided by the invention has good shock resistance and shock resistance, the fibers in the high-ductility cement-based composite material can hinder expansion of internal fine traces, and settlement deformation is greatly reduced due to the high-elasticity characteristic of the high-ductility cement-based composite material.
本发明公开了一种高延性水泥基复合材料制备方法，包括粉煤灰、水泥、砂、水、减水剂、PVA纤维，其中粉煤灰为380kg/m2，水泥为480kg/m2，砂为1150kg/m，水为150kg/m，减水剂为1.5%，PVA纤维为0.5‑1.5%，通过将胶凝材料搅拌均匀后，再将减水剂置于水中搅拌均匀，而后与胶凝混合物充分搅拌至流塑状态，而后加入PVA纤维再次搅拌均匀，最后置于模型中，振动密实，静置24h，养护28d得到高延性水泥基复合材料，本发明提出的高延性水泥基复合材料具有良好的抗冲击和抗震特性，其内的纤维能够阻碍内部细痕扩展，并且其高弹特性大大降低了沉降变形。
