Polypropylene fiber cement-based material and preparation method thereof
The invention discloses a polypropylene fiber cement-based material and a preparation method thereof, and the polypropylene fiber cement-based material comprises the following raw materials by weight: 560-670 parts of cement, 450-560 parts of fly ash, 450-550 parts of fine sand, 13-17 parts of polypropylene monofilament fiber, 6-8 parts of a superplasticizer, and 290-315 parts of water. The fine sand is river sand or silica sand of which the maximum particle size does not exceed 0.6 mm; the diameter of the polypropylene monofilament fiber is 30 microns, and the length of the polypropylene monofilament fiber is 12 mm; the polypropylene monofilament fiber has a Y-shaped section, and the surface is subjected to indentation treatment. The method can be used for preparing the large-deformation cement-based material with typical characteristics of multi-crack cracking and deformation hardening.
本发明公开了一种聚丙烯纤维水泥基材料及其制备方法，以重量份数计，由以下原料组成：水泥560‑670份，粉煤灰450‑560份，细砂450‑550份，聚丙烯单丝纤维13‑17份，高效减水剂6‑8份，水290‑315份；所述细砂为最大粒径不超过0.6mm的河砂或硅砂；所述聚丙烯单丝纤维的直径为30μm，长度为12mm；所述聚丙烯单丝纤维具有Y型截面，表面经压痕处理。本发明可制备出具备多缝开裂和变形硬化典型特征的大变形水泥基材料。
