University of Guilan Concrete Research 2008-4242 3 2 2010 07 01 Durability of Concrete and Mortars Containing Lim Stone Powder in High Density Sulfate Enviroment Durability of Concrete and Mortars Containing Lim Stone Powder in High Density Sulfate Enviroment 27 37 819 FA Mehdi Mehdikhani Ali Akbar Ramezanianpour Ebrahim Ghiyasvand Mohammad Ehsan Kameli Journal Article 1970 01 01 Sulfate attack is one of the most important problems concerning the durability of concrete structures. In this paper, the sulfate resistance of concrete and mortar specimens made from ordinary Portland cement containing limestone powder was studied. Strength reductions and mass changes of concrete specimens immersed in 10% Na2SO4 and MgSO4 solutions and Expansion of mortar prisms immersed in 5% and 10% Na2SO4 and MgSO4 solutions were monitored. It was observed that compressive strength decreases with the limestone replacement percent and also, deterioration is severer, the higher the concentration content sulfate.
