现代化建筑的大跨度、高层化、重载化以及使用环境的局限都要求使用高强混凝土。只有高强混凝土才能有效地减轻结构自重，降低材料用量，减少施工能耗，降低工程造价，大幅度提高使用寿命。在高强混凝土中，采用较小的水灰比、小粒径优质骨料、高标号水泥、矿物掺合料和高...
The use of high-strength concrete is required for large-span, high-rise, heavy-duty, and limited use environments of modern buildings. Only high-strength concrete can effectively reduce the weight of the structure, reduce the amount of materials, reduce construction energy consumption, reduce project cost, and greatly increase service life. In high-strength concrete, smaller water-cement ratio, small-diameter high-quality aggregates, high-grade cement, mineral admixtures and high...
