Resin-coated inorganic nonmetal fiber composite bundle reinforced and toughened cement-based material and preparation method thereof
The invention discloses a resin-coated inorganic nonmetal fiber composite bundle reinforced and toughened cement-based material and a preparation method thereof, and relates to a cement-based material and a preparation method thereof. The invention aims to solve the problems that inorganic non-metal fibers are easy to break due to too small diameters, active silicon oxide in the inorganic non-metal fibers and alkali in cement are subjected to alkali-silicic acid reaction to cause pulverization and failure, and the like. Therefore, the problems that the inorganic non-metal fiber cannot fully exert the anti-impact effect and the reinforcing and toughening effect in the cement-based material and loses efficacy along with the increase of the service time are solved. The resin-coated inorganic nonmetal fiber composite bundle reinforced and toughened cement-based material is prepared from cement, water, fine aggregate, an additive and a resin-coated inorganic nonmetal fiber composite bundle. The cement-based material further comprises a mineral admixture and coarse aggregate. The impact toughness of the resin-coated inorganic non-metal fiber composite bundle reinforced and toughened cement-based material prepared by the invention is improved by more than 10 times compared with that of a cement-based material doped with non-coated resin.
一种树脂裹覆无机非金属纤维复合束增强增韧水泥基材料及其制备方法，它涉及一种水泥基材料及其制备方法。本发明的目的是要解决无机非金属纤维直径过细易发生挫断，以及其中的活性氧化硅与水泥中的碱发生碱硅酸反应而粉化失效等原因，导致无机非金属纤维在水泥基材料中无法充分发挥其抗冲击作用和增强增韧作用以及随服役时间增加而失效的问题。一种树脂裹覆无机非金属纤维复合束增强增韧水泥基材料由水泥、水、细集料、外加剂和树脂裹覆无机非金属纤维复合束制备而成。该水泥基材料还包括矿物掺合料和粗集料。本发明制备的树脂裹覆无机非金属纤维复合束增强增韧水泥基材料的抗冲击韧性较掺加不裹覆树脂的其抗冲击韧性提高10倍以上。
