Recycled fine aggregate high-strength self-compacting concrete and preparation method thereof
The invention discloses recycled fine aggregate high-strength self-compacting concrete and a preparation method thereof. The concrete is prepared from, by weight, 40-50 parts of modified steel slag fiber, 10-20 parts of modified polyurethane, 10-20 parts of modified epoxy resin, 160-170 parts of cement, 250-300 parts of coarse aggregate, 180-200 parts of recycled fine aggregate and 70-80 parts ofwater, wherein the coarse aggregate comprises natural coarse aggregate and recycled coarse aggregate, the natural coarse aggregate is a mixture of broken stone and river sand, and the recycled coarseaggregate is a mixture of slag, broken stone, waste ceramic and building solid waste. The invention discloses a preparation method of the recycled fine aggregate high-strength self-compacting concrete, the prepared concrete is high in strength and excellent in mechanical property, steel slag fibers can be prevented from being corroded by the concrete, and the whole concrete has excellent corrosionresistance, can be applied to extreme environments such as acidic and alkaline environments and is high in practicability.
本发明公开了一种再生细骨料高强自密实混凝土及其制备方法，所述混凝土各组分原料包括：以重量计，改性钢渣纤维40‑50份、改性聚氨酯10‑20份、改性环氧树脂10‑20份、水泥160‑170份、粗骨料250‑300份、再生细骨料180‑200份、水70‑80份；所述粗骨料包括天然粗骨料和再生粗骨料，所述天然粗骨料为碎石、河砂混合物，所述再生粗骨料为炉渣、碎石、废弃陶瓷、建筑固体废弃物混合物；本申请公开了一种再生细骨料高强自密实混凝土的制备方法，制备得到的混凝土的强度高，力学性能优异，且该混凝土能够避免钢渣纤维被腐蚀，整体具有较优异的耐腐蚀性能，可应用于酸性、碱性等极端环境，实用性较高。
