High-performance concrete is composed of the following components in parts by weight: 20 to 25 parts of cement, 45 to 60 parts of an aggregate, 0.1 to 0.15 part of a water reducing agent, 0.16 to 0.2part of a retarder, 0.45 to 0.8 part of a modified additive and water, wherein the water cement ratio is 0.5 to 0.6. The modified additive is a compound of calcium chloride, sodium bentonite, polyacrylamide and alkali-resistant glass fibers in a weight ratio of (1.2-1.5):(0.4-0.5):(1-1.2):(0.4-0.6), and the length of the alkali-resistant glass fibers is 0.8-1 cm. The high-performance concrete hasthe advantages of high early strength, adjustable setting time, good frost resistance and the like.
一种高性能混凝土，由以下重量份的组分组成：水泥20‑25份、骨料45‑60份、减水剂0.1‑0.15份、缓凝剂0.16‑0.2份、改性外加剂0.45‑0.8份和水，其中水灰比为0.5‑0.6。所述改性外加剂为氯化钙、钠基膨润土、聚丙烯酰胺、耐碱玻璃纤维按重量比1.2‑1.5:0.4‑0.5:1‑1.2:0.4‑0.6的复合物，其中耐碱玻璃纤维的长度为0.8‑1cm。该高性能混凝土具有早期强度高、凝结时间可调、抗冻性能好等优点。
