利用双掺技术(掺加粉煤灰与外加剂),文章通过不同掺量配合比对比试验,对高取代情况下粉煤灰混凝土的抗折及耐磨等力学性能进行研究,保证混凝土早期强度达到设计要求,有效地降低混凝土的水化热,减少水泥路面的早期温度裂缝,并具有改善混凝土的施工和易性,后期强度高,低收缩性和低徐变等结构性能。 Using double-doped technology (with fly ash and admixture), the article through the different proportion of mixture ratio test, the high replacement of fly ash concrete flexural and wear-resistant mechanical properties of the study to ensure the concrete early strength Meet the design requirements, effectively reduce the hydration heat of concrete to reduce the early temperature cracks in concrete pavement, and with the construction of work to improve the ease of concrete, high strength, low shrinkage and low creep and other structural properties.
