摘要
采用偏高岭土、粉煤灰和矿渣等量取代水泥,并将偏高岭土与粉煤灰、矿渣分别复掺配制混凝土,对混凝土的工作性、抗压强度和耐久性进行了研究。结果表明,偏高岭土用作混凝土掺合料且掺量合理时,其对混凝土坍落度和抗压强度的影响优于粉煤灰和矿渣,配制的混凝土抗腐蚀性和抗冻融性均有所提高。
Using the metakaolin,fly ash and slag equivalently replacing cement,and using the metakaolin respectively mixing with the fly ash and slag,the specific concrete are prepared.And the workability,compressive strength and durability of concrete are studied.Test results show that,when the metakaolin is used as concrete admixture and the dosage is reasonable,the effects of metakaolin on slump and compressive strength of concrete are better than the effects of fly ash and slag,and the corrosion resistance and freezing-thaw resistance of concrete are improved.
