High-durability recycled aggregate geopolymer concrete and preparation method thereof
The invention belongs to the technical field of concrete preparation, and provides high-durability recycled aggregate geopolymer concrete and a preparation method thereof. The product comprises the following components: 676-747 kg/m < 3 > of a cementing material, 930-940 kg/m < 3 > of coarse aggregate, 620-630 kg/m < 3 > of fine aggregate, 120-150 kg/m < 3 > of water, nano silicon dioxide and steel fibers, the mass ratio of the natural coarse aggregate to the recycled coarse aggregate in the coarse aggregate is (0-100): (0-100); the ratio of the total mass of the nano silicon dioxide and the cementing material to the mass of the nano silicon dioxide is 100: (0-3), and the volume ratio of the steel fibers to the cementing material is (0-3): 100. On the basis that the utilization rate of the recycled coarse aggregate is increased, the nano silicon dioxide and the steel fibers with specific dosages are selected to be matched with the recycled coarse aggregate, and the obtained concrete has excellent anti-freezing, anti-carbonization and anti-permeation performance.
本发明属于混凝土制备技术领域，提供了一种高耐久性再生骨料地聚合物混凝土及其制备方法。该产品包含下列组分：胶凝材料676～747kg/m3、粗骨料930～940kg/m3、细骨料620～630kg/m3、水120～150kg/m3、纳米二氧化硅和钢纤维；粗骨料中天然粗骨料和再生粗骨料的质量比为0～100：0～100；纳米二氧化硅和胶凝材料的总质量与纳米二氧化硅的质量比为100：0～3，钢纤维与胶凝材料的体积比为0～3：100。本发明在提升再生粗骨料利用率的基础上，选用特定用量的纳米二氧化硅和钢纤维与之配合，所得混凝土具备优异的抗冻、抗碳化以及抗渗透性能。
