摘要
在普通混凝土中掺加粉煤灰、硅灰和粉煤灰-硅灰等矿物掺合料,测定混凝土的强度,并结合微观结构分析其对强度的影响。结果表明,短龄期内,粉煤灰和硅灰合掺的混凝土抗压强度最大,掺硅灰的次之,掺粉煤灰的最差。随着龄期的增长,掺粉煤灰混凝土的强度增长最快。
Add minerals admixture such as FA,SF,FA-SF etc into plain concrete to text the strength,and combine with the micro-structure to analyze their influence on strength and abrasion resistance.The results showed that the compressive and flexural strength of FA-SF concrecte is the best,SF concrete comes scend,and the worst is FA in short curing ages.As age increases,the strength of FA-conceret is on the most rise.
