Round valley aggregate RVA is a natural source of aggregate that is found in Tafila in Jordan. For current research, RVA from Al-Hasa valley was considered for testing with crushed limestone aggregate (CLA) from Karak and Tafila sources. 39 samples were collected through the valley at the joint with the lake of Al-Tanour Dam in Tafila. Samples of RVA and CLA were tested and concrete mix at 15, 20, and 2Mpa. ANOVA analysis was conducted to test means' differences in aggregate and concrete properties. Results showed that RVVA has no significant difference in means' properties. While RVA has significant differences when with CLA from Karak and Tafila. Results of ANOVA showed that there is a significant difference in the properties of fresh and hardened concrete for 15 and 25Mpa concrete grades. While significant difference is neglected for 20Mpa concrete grade. Consequently, RVA can be used for concrete mix as CLA.
