Testing the Use of Rounded Valley Aggregate in Concrete Mix in Comparison with Crushed Limestone Aggregate
Year: 2022
Type: article
Abstract: Round valley aggregate RVA is a natural source of aggregate that is found in Tafi la in Jordan.For current research, RVA from Al-Hasa valley was considered for testing with crushed limestone aggregate (CLA) from Karak and Tafi la sources.39 samples were collected through the valley at the joint with the lake of Al-Tanour Dam in Tafi la.Samples of RVA and CLA were tested and concrete mix at 15, 20, and 25 MPa.ANOVA analysis was conducted to test means' diff erences in aggregate and concrete properties.Results showed that RVVA has no signifi cant diff erence in means' properties.While RVA has signifi cant diff erences when with CLA from Karak and Tafi la.Results of ANOVA showed that there is a signifi cant diff erence in the properties of fresh and hardened concrete for 15 and 25 MPa concrete grades.While signifi cant diff erence is neglected for 20 MPa concrete grade.Consequently, RVA can be used for concrete mix as CLA.
