摘要
利用单因素法,通过对不同水胶比和粉煤灰掺量下的大掺量粉煤灰与聚羧酸外加剂双掺时混凝土的抗压强度、抗渗性、抗碳化及抗冲磨等耐久性能的试验结果分析,探讨了大掺量粉煤灰混凝土的特性与机理,为工程设计提供参考。
By single factor method,tests were conducted under different water-binder ratios and fly ash percentages to study the effects of high volume fly ash and Polycarboxylic admixture on concrete durability such as compressive strength,impermeability,carbonization resistance and scour resistance etc.The authors analyze the testing results and discuss the property and mechanism of concrete with high volume fly ash admixture.
