粉煤灰与钢纤维复合高性能道面混凝土试验研究

采用粉煤灰和钢纤维复合的技术路线,研究了粉煤灰等量取代、超量取代、水泥量不变的条件下对钢纤维混凝土性能的影响.结果表明,粉煤灰和钢纤维的掺入可提高道面混凝土的力学性能,改善混凝土的内部结构,并可降低道面混凝土的投资.

Experimental Research on High Performance Pavement Concrete with Fly Ash and Steel Fiber

Using the technique of mixing steel fiber with fly ash,the influences of fly ash on the performances of steel fiber concrete are studied when the fly ash as fine aggregate,replaces cement in the same or excessive quantity or when cement dosage does not change.The results show that the adding fly ash and steel fiber can improve the mechanical properties of pavement concrete,improve the internal structure of concrete and reduce the investment of pavement concrete.
