Preparation method of high-strength concrete cover plate
The invention belongs to the technical field of building materials, and particularly relates to a preparation method of a high-strength concrete cover plate, which comprises the following steps: S1, fully stirring cement, silicon powder, sand and polypropylene fiber to obtain a mixture; s2, adding water, a water reducing agent and a retarder into the mixture, and fully stirring to obtain concrete slurry; s3, after basalt ribs are horizontally placed in the cover plate mold, the concrete grout is poured into the cover plate mold until the height of the liquid level reaches 4/5 of the thickness of the mold; s4, twisting the basalt fiber bundles to obtain twisted basalt fiber bundles; s5, the twisted basalt fiber bundles are inserted into the concrete grout in the mold in the vertical direction; s6, the concrete grout continues to be poured into the mold till the mold is filled with the concrete grout, a layer of fiber net is laid on the surface of the grout, and after the grout is solidified, the cover plate is obtained through curing and demolding; according to the scheme, the mechanical properties of all aspects of the cover plate can be improved.
本发明属于建筑材料技术领域，具体涉及一种高强混凝土盖板的制备方法，包括以下步骤：S1.将水泥、硅粉、砂、聚丙烯纤维充分搅拌得到混合料；S2.向所述混合料中加入水、减水剂和缓凝剂，充分搅拌得到混凝土浆液；S3.在所述盖板模具中水平放入玄武岩筋后，倒入所述混凝土浆液，直至液面高度达到模具厚度的4/5处；S4.将玄武岩纤维束加捻得到加捻玄武岩纤维束；S5.将所述加捻玄武岩纤维束沿竖直方向插入模具中的所述混凝土浆液内；S6.继续向模具内倒入所述混凝土浆液，直至填满模具，在浆液表面铺设一层纤维网，待浆液凝固后，经养护、脱模得到所述盖板；本发明的方案，能够使盖板各方面的力学性能都获得提升。
