Mixed basalt fiber concrete and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to mixed basalt fiber concrete and a preparation method thereof. The mixed basalt fiber concrete is prepared by mixing cement, a mineral admixture, sand, broken stone, chopped basalt fibers, bundled basalt fibers, a water reducing agent and water according to a certain proportion. The concrete comprises the following components in parts by mass: 220 to 280 parts of cement, 130 to 230 parts of the mineral admixture, 635 to 705 parts of sand, 1055 to 1125 parts of broken stone, 1 to 3 parts of chopped basalt fibers, 2 to 8 parts of bundled basalt fibers, 4.3 to 6.4 parts of the water reducing agent and 140 to 160 parts of water. The preparation method comprises the following steps: sequentially adding all the raw materials into a concrete mixer, stirring for several minutes, taking out of the mixer, and loading into a certain test mold. According to the mixed basalt fiber concrete, the crack resistance and the frost resistance of a concrete structure are effectively improved, the preparation method is simple, the applicability is good, and the mixed basalt fiber concrete has a good application prospect.
本发明属于建筑材料技术领域，具体涉及一种混合玄武岩纤维混凝土及其制备方法。该混合玄武岩纤维混凝土由水泥、矿物掺和料、砂、碎石、短切玄武岩纤维、集束玄武岩纤维、减水剂和水按一定比例混合而成，其中各组分所占质量比为水泥（220~280份）：矿物掺和料（130~230份）：砂（635~705份）：碎石（1055~1125份）：短切玄武岩纤维（1~3份）：集束玄武岩纤维（2~8份）：减水剂（4.3~6.4份）：水（140~160份）。其制备方法为把所有原材料依次加入到混凝土搅拌机中搅拌数分钟，出机装入一定的试模即可。该混合玄武岩纤维混凝土有效提高了混凝土结构物的抗裂能力和抗冻性能，且制备方法简单，适用性好，有很好的应用前景。
