Sulfate Contents In Fine Aggregate Fo Concrete

sulfate contents in fine aggregate to concrete. The sulfate content in fine aggregate contains sulfate higher than the acceptable limits in most of the fine aggregate in Middle East countries Al-Kadhimi and Hamid 1983 Al-Ameeri and Issa 2013 results show that the fresh properties such as decreased workability of self-compacting concrete is ...

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 from all concrete ingredients have the ...

Solving high sulfate content of sand used in concrete by ...

2021-1-1  Internal sulfate attack occurs due to the reaction between excess sulfates in concrete ingredients (cement, fine aggregate, crushed aggregate, and water), hydrate (calcium aluminate C 3 A), and moisture. This reaction forms “early ettringite” after hours or days, which is harmless. “delay ettringite” when forming after months or years ...

2021-7-13  In this study, fine stone powder (FSP) generated in the process for producing crushed coarse and fine aggregate was used as a partial replacement for the fine aggregate. The durability of mortars was investigated under sulfate attack in terms of compressive strength loss, change in mass, and expansion. Cement mortars were made with the replacement rate of 0–30% of FSP for fine aggregate
