High-strength fiber concrete and preparation method of high-strength fiber concrete additive
The invention provides high-strength fiber concrete, which comprises the following components in parts by weight: 380-420 kg/m<3> of cement, 30-50 kg/m<3> of mineral powder, 8-10 kg/m<3> of expandingagent, 20-30 kg/m<3> of fiber, 20-30 kg/m<3> of silica fume, 620-680 kg/m<3> of machine-made sand, 1100-1200 kg/m<3> of broken stone, 120-180 kg/m<3> of water and 5-10 kg/m<3> of an additive. According to the invention, steel fibers and polypropylene fibers are doped in concrete, the ratio of each concrete additive is adjusted, and the additives are adjusted, so that the prepared concrete has goodcompressive strength, and the compressive strength of the concrete is obviously increased within a shorter time after pavement construction so as to substantially reduce the construction period of the concrete and improve the fracture resistance and the splitting resistance of a construction pavement.
本发明提供了一种高强纤维混凝土，其各组分按重量计包括水泥380‑420kg/m3、矿粉30‑50kg/m3、膨胀剂8‑10kg/m3、纤维20‑30kg/m3、硅灰20‑30kg/m3、机制砂620‑680kg/m3、碎石1100‑1200kg/m3、水120‑180kg/m3、外加剂5‑10kg/m3。本发明在混凝土中掺杂钢纤维和聚丙烯纤维，并通过调整各混凝土添加物比例，配合外加剂上的调整，使得制得的混凝土具备较好的抗压强度，并且在进行路面施工后在较短的时间内其抗压强度具有一个明显的增幅，大大降低混凝土的施工周期，增加了施工路面的抗折、抗劈裂能力。
