Accelerated Sulphate Attack Study on Cement – Metakaolin – Flyash Concretes

Durability is that property of concrete which plays the prime role in governing lifespan and serviceability a structure with regard to its intended usage. Environmental conditions surroundings are main criteria decide longevity performance concrete. For understanding durability structures, analysis impact chemical attacks may be crucial. As sulphate predominant on their study can interpret it when they subjected deterioration followed by damage. In this study, effectiveness ternary blends OPC metokaolin (MK) flyash (FA) resistance exposed accelerated effect (i.e. wetting drying cycles) 10% solution sodium has been investigated. To assess level sulfate attack, changes strengths specimens weight change were measured after certain numbers cycles. Cubes, prisms cylinders tested for compressive, flexural splitting tensile respectively whereas (in percent) all specimens. Combination MK FA proved improving against attack.
