摘要
通过试验研究了早强减水剂和高效减水剂对掺粉煤灰不同强度等级混凝土抗压强度的影响,研究表明:混凝土中掺入早强减水剂量在0%～1%时,混凝土早期强度明显提高,后期强度也有增大,当粉煤灰掺量为20%、早强减水剂为0.8%时混凝土强度最大;混凝土中掺入高效减水剂量0%～1%,当粉煤灰掺量为25%、高效减水剂为1.0%时混凝土强度最大。
Based on the experiment early strength water-reducing admixture and superplasticizer with different strength grade of fly ash concrete compressive strength,the results show that： the influence of the adding early concrete strong by water dose（0%~1%） in early concrete strength,increase significantly,and post strength also increases.When the fly ash content is 20%,early strength water-reducing admixture for 0.8%,the strength of concrete is the maximum.Concrete adding superplasticizer（0%~1%） inside,when fly ash content is 25%,superplasticizer for 1.0%,the strength of concrete is the maximum.
