Effect of saltwater on cementitious capillary crystalline waterproofing

Abstract

The present studies examine the performance of cementitious capillary crystalline waterproofing coating(CCCW) with Saltwater. As Sri Lanka is a developing country, many underground constructions are being built in coastal areas. This paper aims to review the waterproofing ability of coating on concrete with water, saltwater and seawater. As the main component of seawater is NaCl and the average salt concentration of seawater is 35000 ppm, different concentrations from 8750 ppm to 70000 ppm of saltwater samples are examined. Additionally, a seawater sample is examined as well. Existing results show that there is an effect from saltwater.
