High-dosage stone powder concrete and preparation method thereof
The invention provides high-dosage stone powder concrete and a preparation method thereof, and relates to the technical field of building materials. The invention provides high-dosage stone powder concrete, which is prepared from the following ingredients in parts by mass: 375 to 425 parts of cement, 75 to 125 parts of zeolite powder, 2.5 to 7.5 parts of nanometer materials, 1068 to 1104 parts of coarse aggregates, 676 to 712 parts of fine aggregates, 9 to 10 parts of water reducing agents and 170 to 175 parts of water. The nano material is one or more of nano calcium carbonate, nano silicon dioxide and nano aluminum oxide. The high-dosage zeolite powder is used as the mineral admixture to replace part of cement to prepare the concrete, so that on one hand, the zeolite powder is wide in source, the problem of tension supply of the traditional mineral admixture can be relieved, on the other hand, the dosage of the cement in the concrete can be reduced, and the concrete is environment-friendly and low in cost.
本发明提供了一种大掺量石粉混凝土及其制备方法，涉及建筑材料技术领域。本发明提供的大掺量石粉混凝土，按质量份数计，组分为：水泥375～425份、沸石粉75～125份、纳米材料2.5～7.5份、粗骨料1068～1104份、细骨料676～712份、减水剂9～10份和水170～175份；所述纳米材料为纳米碳酸钙、纳米二氧化硅和纳米三氧化二铝中的一种或多种。本发明利用大掺量沸石粉作为矿物掺合料取代部分水泥制备混凝土，一方面沸石粉来源广，能够缓解传统矿物掺合料供应紧张的问题，另一方面能减少混凝土中水泥的用量，对环境友好且成本低。
