Modified basalt fiber concrete and preparation method thereof
The invention discloses modified basalt fiber concrete and a preparation method thereof, and the modified basalt fiber concrete comprises the following components in percentage by mass: 97-98% of cement matrix, 2-3% of modified basalt fiber, 1-3% of a water reducing agent, 1-3% of a water reducing agent and 1-3% of a water reducing agent. The modified basalt fiber is obtained by carrying out modification treatment on basalt fiber by adopting an N-[3-(trimethoxymethane silyl) propyl] ethylenediamine silane coupling agent. According to the invention, the basalt fiber is modified by using the N-[3-(trimethoxymethane silyl) propyl] ethylenediamine silane coupling agent, so that chemical bond bonding between the surface of the basalt fiber and a cement matrix can be changed, friction between the fiber and concrete is increased, and the toughness and tensile property of the basalt fiber are enhanced; the problem of rapid crack propagation and formation characteristics of basalt fibers is solved, the peak tensile strain and tensile strength of the corresponding modified basalt fiber concrete are greatly improved, and the tensile capacity and plastic characteristics of the concrete are effectively improved.
本发明公开了一种改性玄武岩纤维混凝土及其制备方法，所述改性玄武岩纤维混凝土按质量分数计，包括水泥基体97～98％、改性玄武岩纤维2～3％，所述改性玄武岩纤维采用N‑[3‑(三甲氧基甲烷硅烷基)丙基]乙二胺硅烷偶联剂对玄武岩纤维进行改性处理获得。本发明利用N‑[3‑(三甲氧基甲烷硅烷基)丙基]乙二胺硅烷偶联剂对玄武岩纤维进行改性，其能够改变玄武岩纤维表面与水泥基体的化学键黏结，增加纤维与混凝土之间的摩擦，增强玄武岩纤维的韧性和拉伸性能，解决玄武岩纤维的裂纹快速扩展形成特性，并使得相应的改性玄武岩纤维混凝土的峰值拉伸应变、抗拉强度得到极大提升，有效提升混凝土的抗拉能力与塑性特征。
