摘要
基于价值工程,采用"0-1"强制分析法计算出强度优先和裂缝控制优先两种条件下聚丙烯纤维再生混凝土的性能系数,并分析其经济性。结果表明,强度优先评价时聚丙烯纤维再生混凝土经济性优于裂缝控制优先评价;随着纤维掺量的增加聚丙烯纤维再生混凝土经济性逐渐提高,裂缝控制优先评价经济性提高幅度高于强度优先评价。
Based on the value engineering theory, the performance coefficient of polypropylene fiber recycled concrete is calculated under two conditions of strength priority and crack control priority by using the ＂0-1＂ force analysis method, and the economy of polypropylene fiber recycled concrete is analyzed. The results show that the economy of polypropylene fiber recycled concrete is better than that of crack control priority evaluation in strength priority evaluation.With the increase of fiber content, the economy of polypropylene fiber recycled concrete is gradually improved, and economy increased range under crack control priority evaluation is higher than that under strength priority evaluation.
