EFFECTIVE SULFATE CONTENT IN CONCRETE

2015-7-7  The problem of internal sulfate attack in concrete is widespread in Iraq and neighboring countries. This is because of the high gypsum content usually present in sand and gravel used in concrete. Specifications usually put upper limits of SO3 content in cement, aggregate and concrete. The upper limit of SO3 content is calculated assuming that sulfates
