Composite admixture for improving durability of common concrete by improving grading
The invention belongs to the technical field of building materials, and discloses a composite admixture for improving the durability of common concrete by improving grading. The composite admixture for improving the durability of common concrete by improving grading is composed of the components in parts by mass: 25 to 30 parts of volcanic rock powder, 10 to 15 parts of steel slag, 10 to 15 parts of fly ash, 10 to 15 parts of desulfurized gypsum powder, 8 to 10 parts of carbon fiber, 8 to 12 parts of modified phenolic resin and 5 to 8 parts of activated aluminosilicate mineral. Through cooperation of the fly ash, the volcanic rock powder and the steel slag, proper fluidity can be provided for the concrete, the porosity is reduced, the compactness of a system can be improved, the use amount of water can be reduced, and the durability of the concrete is further improved. The carbon fibers, the modified phenolic resin, the fly ash, the volcanic rock powder and the steel slag are added and blended, so that the pore structure of the concrete is improved, the compactness of the concrete is improved, and the durability of the concrete is improved.
本发明属于建筑材料技术领域，公开了一种通过改进级配提高普通混凝土耐久性的复合掺合料，通过改进级配提高普通混凝土耐久性的复合掺合料按照质量份数由25‑30份火山岩石粉、10‑15份钢渣、10‑15份粉煤灰、脱硫石膏粉10‑15份、碳纤维8‑10份、改性酚醛树脂8‑12份以及5‑8份活化硅铝酸盐矿物组成。本发明通过粉煤灰、火山岩石粉、钢渣的配合，不仅能够提供给混凝土合适的流动性，还减小空隙率可以增加体系的密实，能够减少水的用量，进一步提高混凝土的耐久性。本发明添加碳纤维、改性酚醛树脂与粉煤灰、火山岩石粉、钢渣集配改善了混凝土的孔结构，提高混凝土的密实性，改善混凝土的耐久性。
