Yellow River superfine sand-based high-performance concrete and preparation method thereof
The invention belongs to the technical field of building materials, and relates to Yellow River superfine sand-based high-performance concrete and a preparation method thereof. The concrete is prepared from the following components in parts by weight: 161 to 294 parts of cement, 30 to 60 parts of circulating fluidized bed fly ash, 83 to 132 parts of mineral powder, 270 to 870 parts of Yellow River superfine sand, 270 to 870 parts of machine-made sand, 640 to 680 parts of stone, 2 to 4 parts of CNTs-SAL composite shrinkage-reducing anti-cracking agent, 10 to 30 parts of water reducing agent and 160 to 170 parts of water. The Yellow River superfine sand is used as a raw material to prepare the high-performance concrete, resource utilization of the Yellow River downstream hoarded superfine sand is achieved, the Yellow River superfine sand is round in grain shape, small in grain size and capable of forming good grading complementation with other aggregate and powder components, the overall void ratio of the concrete is reduced, and the strength of the concrete is improved. The working performance of the concrete mixture is improved, and meanwhile, the compactness and the impermeability of the concrete are improved.
本发明属于建筑材料技术领域，涉及一种黄河超细砂基高性能混凝土及其制备方法。按照重量份数计算，包括如下组分：水泥161~294份、循环流化床粉煤灰30~60份、矿粉83~132份、黄河超细砂270~870份、机制砂270~870份、石子640~680份、CNTs‑SAL复合型减缩抗裂剂2~4份，减水剂10~30份，水160~170份。本发明将黄河超细砂砂作为原料制成高性能混凝土，实现了黄河下游囤积超细砂的资源化利用，黄河超细砂粒形圆润，且粒径较小，能够与其他骨料及粉体组分形成良好的级配互补，降低混凝土整体的空隙率，提高了混凝土拌合物的工作性能，同时，提高混凝土的密实性和抗渗性能。
