Preparation method of high-ductility concrete
The invention discloses a preparation method of high-ductility concrete, and relates to the technical field of concrete, the key points of the technical scheme are as follows: raw materials comprise the following materials: cement, fly ash, sand, a water reducing agent, water and PVA fibers, and the mass ratio of the cement to the fly ash to the sand to the water reducing agent to the water to the PVA fibers in unit volume is 407: 407: 293: 1.3: 228: 19.5. According to the high-ductility concrete, the HDC beam is prepared according to the optimal mixing proportion of the raw materials, the HDC beam with high breaking strength is obtained, the HDC beam has good high toughness, high crack resistance and high ductility, the bearing capacity of a wall structure can be improved, the situation of shear brittle failure under the action of large external force is avoided, and the problem of large potential safety hazards is prevented.
本发明公开了一种高延性混凝土的制备方法，涉及混凝土技术领域，其技术方案要点是：原料包括以下材料，水泥、粉煤灰、砂子、减水剂、水和PVA纤维，其中水泥、粉煤灰、砂子、减水剂、水和PVA纤维的单位体积质量比为407：407：293：1.3：228：19.5。该高延性混凝土通过其原料的最适配合比制备HDC梁，得到具有较高抗折强度的HDC梁，使其具备较好的高韧性、高抗裂性能及高延性，能够增大墙体结构的承载力，避免在较大外力作用下发生剪切脆性破坏的情况，防止出现较大的安全隐患的问题。
