Abstract
The need for high-performance concrete with improved workability, higher strength, and greater longevity has risen in recent years to satisfy the current requirements for structural construction. Consequently, the development of self-compacting concrete in Bangladesh has recently become one of the most significant developments in the construction industry. To place and be able to flow under its weight, this innovative concrete does not require additional vibration. The main objective of this study was to investigate the SCC developed in this study using locally available materials incorporating different W/C ratios and different FM of fine aggregate in terms of both fresh and mechanical properties. For the necessary tests, nine mixtures were prepared with different W/C ratios and different FM of fine aggregate, and the same Super-plasticizer dosages. Slump flow, V-funnel, L -box, and T50 were involved in the fresh property tests. However, the experimental results showed that with the reduction of the W/C ratio, compressive strength was improved and the FM of fine aggregate shift is not too much of a compressive strength effect. In comparison, almost all fresh property prices meet the ACI requirements and the W/C ratio 0.4 and 0.45 and 0.5 meet the design specifications of the ACI mix. The compressive strength test is tested in concrete age is 7, 14, and 28 days total of 27 cubes are crushed in the universal testing machine. Therefore, it is invariably possible to use locally available materials to build SCC for sustainable development in Bangladesh
