Abstract

The problem of corrosion has reached major proportions in many parts of the world. This problem has also been encountered in Egypt, especially in the coastal areas. 
The present work was undertaken to compare between corrosion resistance of three types of locally produced cements (ordinary portland, blast furnace, and Sulphate resisting cement). Four Concrete mixes from each cement were chosen to cover most of the practical mixes which are currently used in many structures in Egypt. 
Compressive strength and splitting tensile strength were evaluated after 28, 60, 90 and 120 days for specimens attacked by gulpate as well as for similar control specimens cured by fresh water to be as comparison levels. The variation of strengths gives an idea about the influence of sulphate on concrete specimens. 
As a result of this research, some useful conclusions and practical recommendations have been reached for concrete protection against corrosion.
