Fair-faced concrete and preparation method thereof
The invention discloses fair-faced concrete and a preparation method thereof, relates to the technical field of fair-faced concrete, and adopts the technical scheme that the fair-faced concrete is prepared from the following raw materials in parts by weight: Portland cement, fly ash, mineral powder, medium sand, stones, modified shell powder, collagenous fibers, water and a water reducing agent. The modified shell powder is prepared from a silane coupling agent, shells and collagen fibers in a weight ratio of 1: 50: (100-150). The fair-faced concrete has the advantages of excellent crack resistance, sound absorption and noise reduction.
本发明公开了一种清水混凝土及其制备方法，涉及清水混凝土的技术领域，其技术方案要点是一种清水混凝土，由包含以下重量份的原料制成：硅酸盐水泥，粉煤灰，矿粉，中砂，石子，改性贝壳粉，胶原纤维，水，减水剂；所述改性贝壳粉由重量比为1：50:（100‑150）的硅烷偶联剂、贝壳和胶原纤维制成。本发明的清水混凝土具有优良的抗裂性能和吸音降噪的优点。
