High-performance concrete
The invention discloses high-performance concrete. The high-performance concrete is prepared from the following components: cement, rough aggregate, fine aggregate, water and an additive, each cubic meter of the high-performance concrete comprises the following components: 430-550kg of the cement; 1000 to 1100 kg of the rough aggregate; 650 to 800 kg of the fine aggregate; 150 to 170 kg of the water; and 5-15 kg of the additive. According to the high-performance concrete mineral-free admixture disclosed by the invention, the requirements of the high-performance concrete with different design strength grades are met through a reasonable formula and mixing ratio selection. The antiseepage performance is high in the use process; the volume stability is high; proper high compressive strength is achieved; the high-performance concrete has the advantages of favorable workability, favorable working performance and stable performance, satisfies the standard requirements for durability and strength indexes, solves the goal of preparing the high-performance concrete in admixture-free regions, and can satisfy the construction requirements.
本发明公开了一种高性能混凝土，由以下组分组成：水泥、粗骨料、细骨料、水和外加剂；每立方米高性能混凝土中各组分用量为：水泥430‑550千克；粗骨料1000‑1100千克；细骨料650‑800千克；水150‑170千克；外加剂5‑15千克。本发明高性能混凝土无矿物掺合料，通过合理的组方及其配合比选择，满足不同设计强度等级高性能混凝土要求。在使用时具有高抗渗性；高体积稳定性；适当的高抗压强度；良好的施工性，工作性能良好，性能稳定，耐久性及强度指标满足规范要求，解决了无掺合料地区配制高性能混凝土的目标，能够满足施工要求。
