Aeolian sand concrete and preparation method thereof
The invention relates to aeolian sand concrete and a preparation method, and relates to the technical field of concrete.The aeolian sand concrete is prepared from, by weight, 283 parts of cement, 71 parts of coal ash, 71-214 parts of aeolian sand, 499-642 parts of natural sand, 1163 parts of gravel, 3.54 parts of water reducing agent and 170 parts of underground water, and the aeolian sand accounts for 10%-30% of the total of the aeolian sand and the natural sand. The grain composition of the fine aggregate is improved by reasonably matching the proportion of the aeolian sand and the natural sand, so that the flowability and compressive strength of the concrete are good, the problem that high-performance concrete is difficult to prepare in regions deficient in the natural sand is solved, and meanwhile, the production cost of the concrete is reduced; and the method also plays a positive role in sustainable development of mineral resources and desert control.
本申请涉及一种风积沙混凝土及制备方法，涉及混凝土技术领域，该混凝土中风积沙占风积沙和天然砂总和的10％‑30％，按重量份数计，包含水泥283份、粉煤灰71份、风积沙71‑214份、天然砂499‑642份、碎石1163份、减水剂3.54份、地下水170份。本发明通过合理的搭配风积沙、天然砂的比例来改善细骨料的颗粒级配，使得混凝土的流动性和抗压强度良好，解决了天然砂匮乏地区难以制备高性能混凝土的问题，同时降低了混凝土生产成本，并对矿产资源的可持续发展和沙漠治理方面也能够起到积极作用。
