摘要
从混凝土工作性、抗压强度、抗折强度和耐磨性等方面,分别研究了石灰石粉对道路混凝土性能的影响,并初步探讨了其影响机理。研究结果表明:掺入质量分数为10%的石灰石粉时,道路混凝土具有良好工作性和后期强度;石灰石粉的掺入可提高混凝土的早期耐磨性;双掺石灰石粉和粉煤灰可有效提高混凝土的早期和后期耐磨性能。
The effect of limestone powder on road concrete is studied through the aspects of workability, compressive strength, flexural strength and abrasion resistance and so on. Meanwhile, the mechanism of action is analyzed and discussed. The results show that the road concrete added 10% by mass of limestone powder has good workability and higher later strength. The abrasion resistance of road concrete at early stage can be improved by limestone powder. In addition, the abrasion resistance of road concrete at early and later stage can be improved by mixing limestone powder and fly ash in concrete.
