Basalt fiber reinforced cement-based composite material and preparation method thereof
The invention provides a basalt fiber reinforced cement-based composite material and a preparation method thereof, the basalt fiber reinforced cement-based composite material comprises the following components by weight: 10-24 parts of cement, 20-25 parts of quartz fine sand, 35-55 parts of a mineral admixture, 2-3 parts of magnesium oxide, 0.2-0.5 part of a water reducer, and 5-20 parts of water; the basalt fiber reinforced cement-based composite material further comprises basalt fibers, and the mixing amount of the basalt fibers accounts for 1-3% of the total weight of the cement-based composite material. The basalt fibers are twisted and stranded fibers subjected to impregnating compound coating modification treatment. The cement-based composite material provided by the invention relieves the problem of ECC high-temperature ductility failure, realizes effective resistance to impact load or explosion load, and improves the durability of the cement-based material.
本发明提供一种玄武岩纤维增强水泥基复合材料及其制备方法，以重量份数计，所述玄武岩纤维增强水泥基复合材料包括以下组分：水泥10‑24份，石英细砂20‑25份，矿物掺合料35‑55份，氧化镁2‑3份，减水剂0.2‑0.5份，水5‑20份；所述玄武岩纤维增强水泥基复合材料还包括玄武岩纤维，且所述玄武岩纤维的掺量为水泥基复合材料总重量的1‑3％；所述玄武岩纤维为经过浸润剂涂层改性处理后的加捻合股纤维。本发明提供的水泥基复合材料缓解了ECC高温延性失效问题，实现了其对冲击荷载或爆炸荷载的有效抵抗，提高了水泥基材料的耐久性。
