High-strength concrete for prefabricated stairs and preparation method thereof
The invention relates to the technical field of concrete prefabricated products, in particular to high-strength concrete for prefabricated stairs and a preparation method thereof. The high-strength concrete for the prefabricated stairs is prepared from the following raw materials in parts by weight: 90-120 parts of coarse aggregate, 50-70 parts of fine aggregate, 30-40 parts of cement, 0.5-1 part of a water reducing agent, 1-2 parts of silane coupling agent modified glass fiber, 0.5-1 part of ultra-high molecular weight polyethylene fiber and 10-20 parts of water. The prepared high-strength concrete for the prefabricated stairs has the advantages of high compressive strength and high abrasion resistance.
本申请涉及混凝土预制品技术领域，具体涉及一种高强度预制楼梯用混凝土及其制备方法。按重量份计，所述高强度预制楼梯用混凝土的制备原料包括粗骨料90‑120份、细骨料50‑70份、水泥30‑40份、减水剂0.5‑1份、硅烷偶联剂改性玻璃纤维1‑2份、超高分子量聚乙烯纤维0.5‑1份和水10‑20份。本申请制备的高强度预制楼梯用混凝土具有高抗压强度和高耐磨度的优点。
