High-performance concrete applying machine-made sand
The invention relates to the technical field of building materials, and particularly discloses high-performance concrete applying machine-made sand. The high-performance concrete comprises 239-417 parts of cement, 74-108 parts of fly ash, 638-830 parts of machine-made sand, 1057-1184 parts of broken stone, 3.47-6.38 parts of a high-performance water reducing agent and 137-166 parts of water, wherein the water-binder ratio of the high-performance concrete is 0.28-0.48; the sand rate of the high-performance concrete is 32%-44%; and the MB value of the machine-made sand is smaller than or equal to 1.4, and the crushing value index is 15%-25%. The machine-made sand can be used in high-performance concrete, and the prepared high-performance concrete has high compressive strength and overall performance.
本申请涉及建筑材料技术领域，具体公开了一种应用机制砂的高性能混凝土。高性能混凝土包括水泥239‑417份、粉煤灰74‑108份、机制砂638‑830份、碎石1057‑1184份、高性能减水剂3.47‑6.38份和水137‑166份；高性能混凝土的水胶比为0.28‑0.48；高性能混凝土的砂率为32%‑44%；机制砂的MB值≦1.4，压碎值指数为15%‑25%。本申请的机制砂可用于高性能混凝土中，且制得的高性能混凝土具有良好的抗压强度，整体性能较好。
