Study on Impermeability of Oyster Shell Powder Lightweight Aggregate Concrete
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.
