High-powder-content machine-made sand slope cast-in-place retaining wall concrete and preparation method thereof
The invention relates to the technical field of cement-based building materials, in particular to high-powder-content machine-made sand slope cast-in-place retaining wall concrete and a preparation method thereof.The high-powder-content machine-made sand is used for completely replacing natural sand to serve as fine aggregate, and in order to overcome the influence of machine-made sand and stone powder on the concrete, anti-mud type SAP particles are added; the anti-freezing agent can adsorb stone powder particles in the concrete mixing stage, does not influence the self water release internal curing effect, and ensures the mechanical property, construction property and anti-freezing effect of the side slope cast-in-place retaining wall concrete.
本发明涉及水泥基建筑材料技术领域，尤其是涉及一种高含粉量机制砂边坡现浇挡墙混凝土及其制备方法，使用高含粉机制砂完全替代天然砂作为细骨料，为克服机制砂石粉对混凝土影响，添加抗泥型SAP颗粒，其可在混凝土拌和阶段吸附石粉颗粒，且不影响自身的释水内养护效果，保证边坡现浇挡墙混凝土力学性能、施工性能和抗冻效果。
