Sulfate Resistance and Alkali-Silica Reaction of Recycled Aggregate Concrete

In this research article laboratory investigations of sulfate resistance and alkali-silica reaction recycled aggregate concrete are presented. A total eighteen prisms 25mm x 286mm were prepared using a 1:3 (cement: fine aggregates) mix 0.4 water to binder ratio. The specimens in three batches aggregates, conventional sand. An equal number samples was used evaluate reaction. change length measured standard way from 1- 28 days. results at 14- 28-days show that the percentile all is less than specified limit concerned standards. recorded 14 days (in accordance with ASTM C1260 recommendations) aggregates 342% (for reaction) 57% resistance) better Therefore, performance concluded compared sand for both reactivity resistance.
