High-strength high-modulus nonmetal crude fiber for concrete and preparation method thereof
The invention provides a high-strength high-modulus nonmetal crude fiber for concrete and a preparation method of the high-strength high-modulus nonmetal crude fiber. The high-strength high-modulus nonmetal crude fiber comprises modified polypropylene serving as a base material, wherein a plurality of high-strength high-modulus nonmetal continuous fibers are axially distributed in the base material, and the base material is tightly combined with the nonmetal continuous fibers; when the high-strength high-modulus nonmetal crude fiber is used in concrete, the concrete can be endowed with bettermechanical properties, and meanwhile, the self-weight of the concrete is reduced. Furthermore, the modified polypropylene has excellent alkali resistance, so that the modified polypropylene can keep excellent mechanical properties in strongly alkaline concrete for a long time.
本发明提供了一种用于混凝土的高强高模非金属粗纤维及其制备方法；所述高强高模非金属粗纤维包括作为基材的改性聚丙烯，在所述基材的内部轴向分布有数根高强高模的非金属连续纤维，所述基材与所述非金属连续纤维紧密结合；在混凝土中使用时能够赋予混凝土更优良的力学性能，同时使得混凝土的自重减轻。进一步地，由于改性聚丙烯具有优良的抗碱性能，所以能够在强碱性的混凝土中长期保持优良的力学性能。
