摘要
着重研究采用硅灰裹石掺混合材法对混凝土抗氯离于渗透能力的影响。研究结果表明 :硅灰裹石掺混合材混凝土的抗氯离子渗透能力比普通混凝土提高 30倍 ,比同水灰比、同掺量双掺混合材混凝土提高 1倍以上。此外 ,对硅灰裹石掺混合材法提高混凝土的抗氯离子渗透能力的机理进行探讨。
? Effect of aggregate coated by silica fume and adding admixture on the chloride Resuts showed that the chloride permeability of concrete with aggregate coated by silica fume and adding admixture is 30 time less than that of concrete by adding admixture,Moreover,mechanism of aggregate coated by silica fume and adding admixture exhancing impermeability of concrete was analyzed. 〔
