Large-volume long-life concrete and preparation method thereof
The invention relates to the technical field of building materials, in particular to long-life mass concrete and a preparation method thereof. Comprising 250-350kg/m < 3 > of multi-scale Portland cement; coal ash is 50-200kg/m < 3 >; 0-150kg/m < 3 > of mineral powder; the fine aggregate is 700-900 kg/m < 3 >; 1000-1200 kg/m < 3 > of coarse aggregate; 20-40 kg/m < 3 > of an expanding agent; 0-5 kg/m < 3 > of a capillary crystalline waterproof agent; 5-10 kg/m < 3 > of a water reducing agent; 0-10 kg/m < 3 > of fiber; 150 to 180 kg/m < 3 > of water; the multi-scale Portland cement comprises three kinds of cement with the average particle size of 10-15 microns, 20-25 microns and 30-35 microns respectively. According to the invention, the strength and self-repairing capability of the concrete can be improved, the service life of the concrete is greatly prolonged, and the predicted service life of the concrete can reach 500 years.
本发明涉及建筑材料技术领域，具体为一种长寿命大体积混凝土及其制备方法。包括：多尺度硅酸盐水泥250～350kg/m3；粉煤灰50～200kg/m3；矿粉0～150kg/m3；细骨料700～900kg/m3；粗骨料1000～1200kg/m3；膨胀剂20～40kg/m3；渗透结晶防水剂0～5kg/m3；减水剂5～10kg/m3；纤维0～10kg/m3；水150～180kg/m3；多尺度硅酸盐水泥包括平均粒径分别为10～15um、20～25um和30～35um的三种水泥。本发明可以增加混凝土的强度和自修复能力，大大提升混凝土的服役寿命，预测混凝土服役寿命可达到500年。
