Basalt fiber reinforced concrete and preparation method thereof
The invention relates to basalt fiber reinforced concrete and a preparation method thereof. The basalt fiber reinforced concrete is prepared from the following raw materials: cement, silica fume, fly ash, fine aggregate, coarse aggregate, a water reducing agent, water and basalt fibers. Wherein the diameter of the basalt fiber is 15 microns, the length of the basalt fiber is 19 mm, the density of the basalt fiber is 2.71 g/cm < 3 >, and the tensile strength of the basalt fiber is 4500 MPa. In the invention, when the basalt fiber is applied to the concrete, the close combination of the basalt fiber and the cement matrix can effectively absorb the tensile stress of the concrete and improve the crack resistance of the concrete, so that the generation of cracks can be inhibited and reduced, and the durability and breaking strength of the concrete are improved; therefore, the serious safety problem exposed when the breaking strength of the concrete structure is insufficient is avoided.
本公开涉及一种玄武岩纤维增强混凝土及其制备方法，所述玄武岩纤维增强混凝土的制备原料包括水泥、硅灰、粉煤灰、细骨料、粗骨料、减水剂、水和玄武岩纤维；其中，所述玄武岩纤维的直径为15μm、长度为19mm、密度为2.71g/cm3、抗拉强度为4500MPa。在本公开中，将玄武岩纤维应用于混凝土中时，玄武岩纤维与水泥基体的密切组合可以有效吸收混凝土的拉应力，提高混凝土阻裂能力，进而能够抑制和减少裂缝的产生，提高混凝土耐久性以及抗折强度，从而避免混凝土结构在抗折强度不足时暴露出的严重的安全性问题。
