An experimental study was executed to review the effectiveness of mineral additives over the strength and flexural performance of SCC mix trials subjected to monotonic loads. RCC beam specimens of desired grade were casted in the present study. To assess the fresh properties of concrete slump flow, U-Box, V-Funnel and L-Box test were done and for hardened characteristics compressive as well as tensile strength tests were performed for 7 days and 28 days. Monotonic loading was displacement-controlled for this test. Test results indicate that the stress-strain relationship was linear at the initial stage while non-linearity gradually developed with the increasing load as the stiffness reduces. The faster rate of loading retards the propagation of internal micro-cracks and develops the external cracks.
