摘　　要：为研究牡蛎壳颗粒代替部分细骨料混凝土抗渗性能的影响,选用牡蛎壳碎替代细骨料,分为0%、20%、40%、60%四个梯度,在规定龄期下标准养护,进行了混凝土渗透性试验,结果表明:以牡蛎壳颗粒代替细骨料配制的C30混凝土抗渗等级都比普通混凝土的抗渗等级小,并随着牡蛎壳掺加料的增加,混凝土抗渗等级不断下降。In order to study the influence of oyster shell particles replacing part of fine aggregate on the impermeability of concrete,oyster shell fragments were selected to replace fine aggregate,which were divided into 0%,20%,40%,60%and four gradients,and the concrete permeability test was carried out under the standard curing at the specified age.The results show that the impermeability grade of C30 concrete made of oyster shell particles instead of fine aggregate is lower than that of ordinary concrete,and the impermeability grade of concrete decreases with the increase of oyster shell additives.
