Abstract: Harmful substances such as chlorides or sulfates are dissolved in water and they can easily penetrate into concrete with water. Water proofing admixtures added into concrete during the production is one of the methods for reducing the water permeability of concrete. In this experimental study, commonly used water proofing admixtures available in the market were selected and concrete mixtures having the same water/cement ratios but containing different water proofing admixtures, were produced. Control mixtures without any admixture were also prepared. For comparison purposes, mixtures without any water proofing admixtures but lower water/cement ratios were also produced. In order to determine the permeability characteristics; capillary water absorption, water penetration depth under pressure, water absorption and electrical resistivity tests were performed on the concretes. Compressive strengths of the mixtures were also determined. Results obtained show the differences between the effectiveness of the admixtures. A cost analysis was also performed, results of which indicate that use of water proofing admixtures is not always the optimum solution for obtaining low permeability concrete.
