ENGINEERING AND MECHANICAL PROPERTIES OF SELF-COMPACTING CONCRETE USING FLY ASH AND METAKAOLIN

Abstract

The purpose of this research was to investigate the performance of self-consolidating concrete (SCC) that included fly ash and glass fibers, particularly with regard to its workability, mechanical properties, and other characteristics. In lieu of cement, the concrete mixture included thirty percent fly ash and metakaolin in varying proportions of five percent, ten percent, and fifteen percent. A weight ratio of 0.25 percent of the binder in the concrete is comprised of glass fibre that is incorporated into the aggregate. The use of concrete samples that have recently been created is acceptable. T50 and J-ring procedures were used in order to conduct the evaluation of the slump flow. Over the course of 28 and 56 days, concrete that had been hardened underwent tests to determine its compressive, tensile, and flexural strengths, which are all indicators of its overall strength. The concrete grade was M30, and the ratio of water to binder was maintained at 0.35 throughout the process. The self-compacting concrete (SCC) exhibits superior performance in terms of its mechanical properties when compared to the control mixture. In addition, the SCC composite has all of the benefits that are associated with fresh concrete, such as the capacity to fill voids in an effective manner and to flow without any interruptions. A great amount of resilience is shown by the SCC when it is subjected to the environment that is immediately around it. The conclusion that can be drawn from this is that the SCC's efficient waste management contributes to an increase in sustainability.
