The invention relates to the technical field of building materials, in particular to high-substitution-rate desert sand concrete as well as a preparation method and application thereof. The high-substitution-rate desert sand concrete is prepared from raw materials including cement, fly ash, fine aggregate and coarse aggregate, the fine aggregate is common sand and desert sand, and the desert sand accounts for 60-80% of the total mass of the fine aggregate; the fly ash accounts for 10-30% of the total mass of the cement and the fly ash, the water-binder ratio is 0.42-0.55, and the sand ratio is 33-37%. According to the desert sand concrete with the high substitution rate, desert sand resources can be fully utilized under the condition that the performance of the concrete is guaranteed, and the chloride ion penetration resistance of the concrete can be remarkably improved.
本发明涉及建筑材料技术领域，尤其涉及一种高替代率沙漠砂混凝土及其制备方法和应用。该高替代率沙漠砂混凝土由包含水泥、粉煤灰、细骨料和粗骨料的原料制备而成，所述细骨料为普通砂和沙漠砂，所述沙漠砂占细骨料总质量的60～80％；所述粉煤灰占水泥和粉煤灰总质量的10～30％，水胶比为0.42～0.55，砂率为33～37％。本发明提供的高替代率沙漠砂混凝土可在保证混凝土性能的情况下，充分利用沙漠砂资源，并能显著提高混凝土的抗氯离子渗透性能。
