摘　　要：通过在高强混凝土中加入不同掺量的钢渣和超细粉煤灰,研究了钢渣和超细粉煤灰对高强混凝土工作性能、抗压性能、绝热温升、自生收缩、抗碳化性能及氯离子渗透性能的影响。实验结果表明:掺入钢渣和超细粉煤灰会略降低高强混凝土流动性,对高强混凝土的抗碳化性能无明显影响,但能够降低其绝热温升和自生收缩,并能够提高其后期强度及抗氯离子渗透性能。By incorporating different dosage of ultrafine fly ash and steel slag in high-strength concrete, its properties such as compressive strength, adiabatic temperature rise, autogenous shrinkage, carbonation resistance and chloride ion penetration performance were investigated. The results show that the addition of steel slag and uhrafine fly ash has a little negative effect on the workability of concrete and limited effect on the carbonation resistance, but it can reduce the adiabatic temperature rise and autogenous shrinkage , and it can improve its later strength and resistance to chloride ion permeability.
