- The increasing demand for high-performance construction materials has led to the development of high-strength concrete with improved mechanical and structural properties. This study focuses on the development of M90 high-strength concrete using supplementary cementitious materials (SCMs) such as fly ash, ground granulated blast furnace slag (GGBS), micro silica, quartz sand, and quartz powder. Steel fibres of two different sizes (30 mm × 0.6 mm and 60 mm × 0.75 mm) were incorporated to enhance ductility and crack resistance. A conventional M30 concrete mix was used as a control mix to evaluate the structural performance of the developed M90 concrete. Experimental investigations included compressive strength testing and cyclic loading tests on reinforced concrete beams and frames. The results indicated that the first crack load increased from 17 kN in M30 beams to 50 kN in M90 beams, with improved crack distribution and reduced crack width due to the presence of steel fibres. The M90 concrete exhibited enhanced flexural performance and energy dissipation under cyclic loading, indicating its potential suitability for seismic-resistant structural applications.
