摘要
采用优质矿物掺合料与高效减水剂双掺技术,成功配制出强度等级在C40～C60的高性能再生混凝土。采用电液伺服压力试验机对高性能再生混凝土进行单轴受压试验,测得其应力应变全曲线并进行了理论分析和比较,给出了高性能再生混凝土单轴受压应力应变全曲线的数学表达式,其理论曲线与试验结果吻合较好。
The high performance recycled concrete can be developed by double-mixture of mineral admixture and superplasticizer. Uniaxial compression experiments for the high performance recycled concrete were conducted by using electro-hydraulic testing machine. On the basis of the stress-strain curves the constitutive equation was established, theoretical curves from calculation are in good agreement with experimental curves.
