Fair-faced concrete and preparation method thereof
The invention relates to fair-faced concrete and a preparation method thereof. According to the method, the concrete is prepared from 115-125 parts of sand, 240-260 parts of stone, 110 parts of cement, 33-36 parts of water, 6-7.5 parts of a water reducing agent, 4-6 parts of reinforcing fibers, 2-3 parts of polyether modified organic silicon, 2-4 parts of a water-retaining agent and 4-6 parts of paper pulp. The concrete disclosed by the invention is better in strength, the anti-cracking property is enhanced, and unqualified products are avoided; besides, viscosity of the concrete is increased, collapse is prevented, and the high plasticity maintaining effect is better.
本发明涉及清水混凝土及其制备方法，包括砂子115‑125份、石子240‑260份、水泥110份、水33‑36份、减水剂6份‑7.5份、加强纤维4份‑6份、聚醚改性有机硅2份‑3份、保水剂2份‑4份、纸浆4份‑6份，本发明所述混凝土的强度更好以及增强防开裂性，避免产品不合格，且增加了混凝土的粘稠度，防止塌落，且高保塑效果更好。
