High-strength concrete and preparation method thereof
The invention relates to the technical field of concrete materials, in particular to high-strength concrete and a preparation method thereof. The high-strength concrete is prepared from the following raw materials in parts by mass: 450 to 500 parts of cement, 160 to 200 parts of modified glass beads, 700 to 800 parts of aggregate, 200 to 250 parts of fly ash, 10 to 15 parts of calcium hydroxide, 12 to 15 parts of reinforced fibers, 8 to 12 parts of expansion filler, 8 to 12 parts of high-efficiency water reducing agent and 200 to 220 parts of water, and the reinforced fibers are prepared from steel fibers, basalt fibers and modified polypropylene fibers. The high-strength concrete shows excellent properties in multiple aspects, including improvement of mechanical properties, enhancement of durability and crack resistance, improvement of workability, improvement of self-repairing capability, reduction of temperature cracks and the like, and the high-strength concrete has wide application potential in constructional engineering due to the technical effects.
本申请涉及混凝土材料技术领域，尤其涉及一种高强混凝土及其制备方法。一种高强混凝土，按质量份数计，包括以下制备原料：水泥450‑500份、改性玻璃微珠160‑200份、骨料700‑800份、粉煤灰200‑250份、氢氧化钙10‑15份、增强纤维12‑15份、膨胀填料8‑12份、高效减水剂8‑12份、水200‑220份，其中，所述增强纤维由钢纤维、玄武岩纤维和改性聚丙烯纤维组成。本申请的高强混凝土在多个方面展现出了优异的性能，包括力学性能的提升、耐久性和抗裂性的增强、工作性的改善、自修复能力的提高以及温度裂缝的减少等，这些技术效果使其在建筑工程中具有广泛的应用潜力。
