Large-volume shrinkage-compensating concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses large-volume shrinkage-compensating concrete and a preparation method thereof. The large-volume shrinkage-compensating concrete is prepared from the following components in parts by weight: 150 to 200 parts of cement, 40 to 80 parts of fly ash, 90 to 120 parts of mineral powder, 20 to 35 parts of an expanding agent, 700 to 900 parts of machine-made sand, 1000 to 1200 parts of broken stone, 5 to 9 parts of a water reducing agent, 3 to 5 parts of a hydration heat inhibitor and 140 to 180 parts of water, the hydration heat inhibitor comprises potato starch, sodium silicate, lauryl sodium sulfate, beta-cyclodextrin and ascorbic acid. The large-volume shrinkage-compensating concrete can effectively compensate shrinkage and reduce concrete cracks.
本发明涉及混凝土技术领域，具体公开了一种大体积补偿收缩混凝土及其制备方法。一种大体积补偿收缩混凝土，包括以下重量份的组分：150~200份水泥、40~80份粉煤灰、90~120份矿粉、20~35份膨胀剂、700~900份机制砂、1000~1200份碎石、5~9份减水剂、3~5份水化热抑制剂、140~180份水；所述水化热抑制剂包括马铃薯淀粉、硅酸钠、十二烷基硫酸钠、β‑环糊精和抗坏血酸。本申请的一种大体积补偿收缩混凝土能够有效补偿收缩并减少混凝土裂缝。
