Plain concrete for roadbed slope protection and preparation method thereof
The invention relates to the technical field of road construction, and particularly discloses plain concrete for roadbed slope protection and a preparation method of the plain concrete. The plain concrete is formed by pouring a concrete mixture, the concrete mixture is prepared from the following components in parts by weight: 137 to 145 parts of Portland cement, 112 to 116 parts of fly ash, 735 to 755 parts of sand, 1403 to 1423 parts of gravel, 50 to 70 parts of sintered brick particles, 105 to 109 parts of water, 2 to 2.4 parts of a water reducing agent and 1.2 to 4.8 parts of modified fibers, and the modified fibers are acrylic fibers with carboxyl groups on the surfaces. According to the scheme, the total quantity of the residual bleeding channels in the plain concrete can be reduced, so that the influence of the bleeding channels on the freeze-thaw resistance of the plain concrete is reduced, the freeze-thaw damage of the plain concrete is reduced, and the protection effect of the plain concrete on a side slope is improved.
本申请涉及道路施工技术领域，具体公开了一种路基边坡防护用素混凝土及其制备方法。所述素混凝土由混凝土拌和物浇筑而成，所述混凝土拌和物包括如下重量份的组分：硅酸盐水泥137‑145份，粉煤灰112‑116份，砂735‑755份，碎石1403‑1423份，烧结砖颗粒50‑70份，水105‑109份，减水剂2‑2.4份，改性纤维1.2‑4.8份，所述改性纤维为表面带有羧基的腈纶纤维。本申请的方案能够减少素混凝土内部残留的泌水通道总量，从而降低了泌水通道对素混凝土的抗冻融性能造成的影响，有助于减少素混凝土的冻融破坏，并改善素混凝土对边坡的防护效果。
