Formula and preparation method of C60 strength grade steel fiber recycled concrete
The invention discloses a C60 strength grade steel fiber recycled concrete formula and a preparation method, and relates to the technical field of civil engineering concrete.The steel fiber recycled concrete formula comprises the following raw materials in parts by mass per cubic meter: 70.2-85.8 parts of steel fibers; 330 to 340 parts of cement; 1120 to 1130 parts of recycled coarse aggregate; 630 to 640 parts of fine aggregate; 140 to 150 parts of a mineral admixture; 0.2 to 0.5 part of a high-performance water reducing agent; 150 to 160 parts of water; the concrete produced according to the formula is subjected to a slump test, and the actually measured slump reaches 180 mm or above; through 28d actual measurement compressive strength tests, the compressive strength of the recycled concrete can reach 69MPa or above, the breaking strength can reach 7.2 MPa or above, and both the compressive strength and the breaking strength reach the C60 strength grade standard; the mixing proportion of the C60 steel fiber recycled concrete is optimized, so that the C60 steel fiber recycled concrete is more suitable for being poured on structural beams, plates and columns, and the problem of construction waste disposal is fundamentally solved.
本申请公开了一种C60强度等级钢纤维再生混凝土配方及制备方法，涉及土木工程混凝土技术领域，本申请的钢纤维再生混凝土配方每立方米包括如下质量份数的原料：钢纤维：70.2～85.8份；水泥∶330～340份；再生粗骨料∶1120～1130份；细骨料∶630～640份；矿物掺合料：140～150份；高性能减水剂：0.2～0.5份；水：150～160份；该配方生产的混凝土经过坍落度试验，实测坍落度均达到180mm以上；经过28d实测抗压强度试验，再生混凝土抗压强度均可达69MPa以上，抗折强度可达7.2MPa以上，均达到C60强度等级标准；本申请优化了C60钢纤维再生混凝土配合比，使其更适于浇筑在结构梁、板、柱上，在根本上解决了建筑垃圾处置的问题。
