摘　　要：利用地方原材料,在自密实混凝土初步配合比基础上,采用正交试验优化配制出C25芯柱自密实混凝土,分析了粉煤灰掺量、砂率、高效减水剂和增稠剂掺量等主要因素对自密实混凝土性能的影响,并与同强度等级C25混凝土进行了经济分析。Based on the initial self-compacting concrete mix,C25 core-column of self-compacting concrete was optimized with local raw materials through orthogonal test.The main impacting factors such as content of fly ash, sand ratio, and the amount of thickener and superplasticizer were analyzed on the performance of self-compacting concrete with the economic comparison on the same grade of C25.
