摘 要:通过加速碳化方法,研究了水工混凝土单掺花岗岩石粉、单掺粉煤灰及双掺花岗岩石粉及粉煤灰时的抗碳化性能。结果表明,水工混凝土双掺矿物掺合料时的抗碳化性能优于单掺矿物掺合料时的抗碳化性能,且混凝土抗碳化性能随着矿物掺合料掺量及细度的变化,呈现规律性变化。
Abstract: The carbonation resistances of hydraulic concrete mixed with granitic powder or fly ash and hydraulic concrete double mixed with granitic powder and fly ash are studied through the method of accelerated carbonation. And the results show that the carbonation resistance of hydraulic concrete double mixed with granitic powder and fly ash is better than that of hydraulic concrete single mixed with admixture, and the carbonation resistance is changed regularly with the change of content and fineness of mineral admixtures.
