Environment-friendly high-performance concrete and preparation method thereof
The invention relates to the technical field of concrete, in particular to environment-friendly high-performance concrete and a preparation method thereof. The concrete is prepared from the followingraw materials in parts by weight: 100 parts of cement, 20 to 50 parts of waste concrete, 10 to 40 parts of fly ash, 10 to 35 parts of lightweight fine aggregate, 5-30 parts of ceramsite, 5-20 parts ofmodified straw powder, 1-5 parts of carbon fibers, 1 to 15 parts of glass beads, 5 to 10 parts of a water reducing agent and 100 to 400 parts of water, wherein the modified straw powder is polyacrylic acid fiber modified straw powder. According to a technical scheme in the invention, the green environment-friendly high-performance concrete has high compressive strength and breaking strength, goodanti-freezing performance and flame-retardant performance and wide application prospects.
本发明涉及混凝土技术领域，具体涉及一种绿色环保高性能混凝土及其制备方法。所述绿色环保高性能混凝土的制备原料包括以下组分，以重量份计：水泥100份；废旧混凝土20‑50份；粉煤灰10‑40份；轻质细骨料10‑35份；陶粒5‑30份；改性秸秆粉末5‑20份；碳纤维1‑5份；玻化微珠1‑15份；减水剂5‑10份和水100‑400份；所述改性秸秆粉末为聚丙烯酸纤维改性秸秆粉末。本申请的技术方案中的绿色环保高性能混凝土具有较高的抗压强度、抗折强度、较好的抗冻性能以及阻燃性能，应用前景广阔。
