Abstract:This report highlights the production of self-consolidating concrete (SCC) using local materials from Las Vegas, Nevada. Four SCC mixtures were worked on with 2 different levels of fly ash (FA) replacement and the inclusion of superplasticizers, ADVA 195 and V-MAR 3. The fresh properties tested of these mixtures are the flowability, passing ability and the stability. The mechanical properties were also ascertained and these comprised the compressive strength, splitting tensile strength and the modulus of elasticity. The durability of the specimens produced from the mixtures was tested against chloride ion resistance, sulfate resistance and salt scaling. The effect of the concrete constituents on the results obtained from fresh and hardened properties is also discussed. Moreover, this report investigates the difference in the behavior of SCC and conventional concrete encased in fiber reinforced polymer (FRP) tubes. The effect of fiber orientation on both strength and ductility of FRP confined concrete is discussed. Axial compression tests were performed under monotonic and cyclic conditions to determine the stress strain relationship of a SCC filled fiber tube with ±45° fibers. The test results obtained from the compression tests are presented and examined.
