The results demonstrated the greater resistance with lower water cement ratio, much greater resistance with ground granulated blastfurnace slag (GGBS) and the highest resistance values for the samples with entrained air. The calculated transit velocities showed that they were an excellent indicator of the level of damage within the concrete.

Abstract: In order to ascertain the fire resistance performance of recycled aggregate concrete (RAC) components with different concrete compressive strengths, four fullscaled concrete columns were designed and tested under high temperature. Two of the four specimens were constructed by normal concrete with compressive strength ratings of C20

Effect of metallic aggregate and cement content on abrasion resistance behaviour of concrete O. Gencel*1,2, M. Sabri Gok3 and W. Brostow2 Many concrete structures are required to have sufficient abrasion resistance, such as dams, canals, roads and floors. The abrasion resistance of concrete may be defined as its ability to resist
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
