“…Since aggregate composes about 75% of concrete volume, aggregate affects the properties of concrete [16]. The shape of aggregate affects concrete workability in fresh stage and compressive strength in hardened stage and finally durability of concrete [2]. Elongation flatness factors, shape factor, sphericity, and roundness are factors affect mostly concrete properties.…”

“…The trials to improve concrete performance and quality are essential steps for the whole development of building and construction process through technology and materials to avoid overruns in time and cost [2]. The development process can be achieved through the development on cement the binder agent, natural and/or artificial fi bers, or through the use of coarse and fi ne aggregates from new sources.…”

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.

This research investigated the effect of using micro-nano bubbles and superplasticizers on the rheology of self-compacting concrete (SCC). Eight mix designs were made with different values of 4-5.5 kg/m 3 of superplasticizer. For comparison, half of the mix designs were made with micro-nano bubbles, and the rest were made with tap water. Flowability, passing ability, and rheological tests were performed on all mixed designs. The results show that an increased rate of superplasticizer from 4 to 5 kg/m 3 improved flowability and passing ability in all specimens. The yield stress and plastic viscosity of SCC reduction were higher in samples made with micro-nano bubbles. The shear-thickening behavior was observed in SCC samples produced with tap water and the superplasticizer, and the c/μ (positive) ratio increased. While in SCC with micronano bubbles, the shear-thinning behavior was observed, and the c/μ (negative) ratio increased with increasing the superplasticizer dose.
