A Study and Analysis of Stress Strain Behaviour of Self Compacting Concrete With or with Out Confinement by Partial Replacement of Cement With Fly Ash
For numerical simulation of the structural behavior of reinforced concrete structural elements, analytical models for the complete stress – strain relationship of confined and unconfined concrete in compression are needed. The experimental work was done to observe the effects on fresh and solidified properties of SCC during the treatment of pond ash. Replacement of fly ash by weight of fine aggregates in various percentages such as 20%, 40%, 60%, by weight of cement is replaced as a mineral admixture to attain self-compacting concrete properties to predict flow behaviour. It is recognized that the stress-strain behavior of concrete under uniaxial compressive loading is influenced by the concrete constituents. A special type of concrete, i.e. self-compacting concrete (SCC) incorporating high-volume fly ash, has different constituents to that of conventional concrete. To investigate the effectiveness of transverse steel on M 40 grade concrete under monotonically increasing axial compression. The behavior of SCC cylinders confined by circular hoops and square prisms by rectilinear hoops with different volumetric ratios and spacing were compared under axial compression. The impact on the behavior of SCC specimens of test variables such as volumetric ratio, spacing and cross section shape are described and discussed. The results revealed that the more containment steel volumes, the greater the rise in peak stress and deformability. The super plasticizer is used to improve the workability of SCC by 1 per cent weight of cement. This replacement had been shown to have some economic advantages as well as time-efficient techniques for future concreting.
