Desert sand polymer super-tough concrete and preparation method thereof
The invention discloses desert sand polymer super-tough concrete and a preparation method thereof, and belongs to the technical field of concrete materials, the concrete comprises the following components by mass: 1000 parts of fly ash, 0-400 parts of river sand, 0-400 parts of desert sand, 300-600 parts of water glass, 50-70 parts of NaOH particles, 100-150 parts of water, 20 parts of a water reducer, and 20-30 parts of PVA fiber. The concrete is green and environment-friendly, and the concrete material is high in corrosion resistance and sealing performance, long in service life, good in strength and good in tensile strength and bending toughness; the fine-particle desert sand with the smooth surface increases the workability of the concrete, and the strength of the concrete is improved to a certain extent. And the concrete has ultrahigh toughness and ductility, can be applied to paving and repairing of rural roads, and further can be applied to slope reinforcement, building repair, bridge deck slab correction and other anti-seismic and anti-impact structures.
本发明公开了一种沙漠沙地聚物超韧混凝土及其制备方法，属于混凝土材料技术领域，其混凝土组成成分，按质量计分别为：粉煤灰1000份、河砂0‑400份、沙漠沙0‑400份、水玻璃300‑600份、NaOH颗粒50‑70份、水100‑150份、减水剂20份、PVA纤维20‑30份。本发明绿色环保，混凝土材料耐腐蚀性、密封性强、使用寿命长、强度好、抗拉和弯曲韧性较好；细微颗粒且表面圆滑的沙漠沙增加了混凝土的和易性，一定程度的提高了混凝土的强度。且其具有超高韧性和延性，可以应用到乡村道路的铺设及修补上，进而应用到边坡加固、建筑物修补、桥面板修正及其他抗震、抗冲击结构中。
