一种用于水工大体积抗裂混凝土及其制备方法
摘要：
本发明提供一种用于水工大体积抗裂混凝土及其制备方法，所述用于水工大体积抗裂混凝土的组分包括：水泥、粉煤灰、膨胀剂、水、砂、碎石、减水剂；其中，各组分质量配比为：水泥5-10％，粉煤灰2-4％，膨胀剂1-2％，水5-10％，砂28-32％，碎石50-55％，减水剂0.05-0.1％，各组分质量百分比总和满足100％。本发明的用于水工大体积抗裂混凝土的抗压、劈拉强度相对于由传统U型膨胀剂制成的补偿收缩混凝土有明显的提升、且抗裂性能明显增强。
摘要（英）：

The invention provides a hydraulic large-volume crack-resistant concrete and a preparation method thereof. The hydraulic large-volume crack-resistant concrete is prepared from, by mass, 5-10% of cement, 2-4% of fly ash, 1-2% of an expansion agent, 5-10% of water, 28-32% of sand, 50-55% of detritus and 0.05-0.15 of a water reducer. The compressive resistance and splitting tensile strength of the hydraulic large-volume crack-resistant concrete are remarkably improved compared with compensation shrinkage concrete made of a traditional U-shaped expansion agent, and the crack resistance is remarkably enhanced.
