Alkali-resistant glass fiber ultra-high performance concrete and preparation method thereof
The invention relates to the technical field of ultra-high performance concrete preparation, discloses alkali-resistant glass fiber ultra-high performance concrete and a preparation method thereof, and belongs to the technical field of building materials. The alkali-resistant glass fiber ultra-high performance concrete is prepared from the following raw materials in parts by weight: 80 to 100 parts of Portland cement, 100 to 120 parts of aggregate, 90 to 100 parts of admixture, 200 to 220 parts of purified water, 10 to 15 parts of water reducing agent and 30 to 50 parts of glass fiber. According to the invention, by optimizing the raw material proportioning and introducing the alkali-resistant glass fiber, the defects that steel fiber ultra-high performance concrete and basalt fiber ultra-high performance concrete are poor in durability and fatigue resistance, and fibers are easy to corrode, easy to entangle and non-uniform in dispersion in the prior art are overcome. The compression resistance, the splitting resistance, the fracture resistance, the durability and the toughness of the concrete material are improved, and the shrinkage cracking of the concrete is reduced.
本发明涉及超高性能混凝土制备技术领域，公开了一种耐碱玻璃纤维超高性能混凝土及其制备方法，属于建筑材料技术领域。所述耐碱玻璃纤维超高性能混凝土的原料按重量份数计，包括：硅酸盐水泥80‑100份、集料100‑120份、掺合料90‑100份、纯净水200‑220份、减水剂10‑15份、玻璃纤维30‑50份。本发明通过优化原料配料，引入耐碱玻璃纤维，以改善现有技术中，钢纤维超高性能混凝土和玄武岩纤维超高性能混凝土耐久性差、抗疲劳性能弱、纤维易腐蚀、易缠结、分散不均匀的缺点。提高混凝土材料抗压性能、抗劈裂性能、抗折性能以及耐久性和韧性，减少混凝土收缩开裂。
