Abstract

This study has been investigated the effect of admixtures on the strength of concrete under water with high aggressive ions, for example under Urmia-lake water in West Azerbaijan, Iran. We made different types of concretes with the ratio of w/c and replaced different percentages of micro-silica, air-entraining, super plasticizer, corrosion-inhibiting and caulk with two types of cement I and II as well as investigating in both ordinary water and Urmia-lake water. The strength of pressure, tension, abrasion and freezing and melting was investigated on these samples. The results indicate that admixtures improved strength of concrete under water with high aggressive ions. Finally, the most proper mixture was presented using both types of cement (I and II) and optimal value for micro-silica, caulk and super plasticizer.
