Abstract

The innovations in concrete being engineered to the specific requirements have found a new dimension under sustainability. Alccofine is a sustainable construction material derived from GGBS. The primary objective of the study is to explore the potential of Alccofine particles in varying proportions in combination with 0.5% steel fibers to uplift the flexural strength of the engineered concrete. As concrete is known to be a brittle material once hardened, exhibits remarkable resistance to compressive stress, whereas, the ductility of concrete is comparatively low. The study is mainly focused on arriving at an optimum combination of Alccofine with constant steel fiber (0.5%) for the M70 grade of concrete based on the flexural behavior of RC beams. The experimental analysis on load vs deflection and the stress-strain graphs fetches the critical parameters such as ductility index and relative stiffness of the combinations. Based on these crucial flexure parameters, the 10% Alccofine with 0.5% steel highlights to be an effective combination of engineered concrete. Both under-reinforced and over-reinforced sections were implemented to these varying combinations. The results depict the extended deflection range for over-reinforced sections compared to under-reinforced sections. The overall observations through experimental analysis conclude that up to 10% Alccofine replacement to cement and the addition of 0.5% steel fiber enhances Young’s modulus of the engineered concrete, thereby contributing to the ductile behavior of concrete. The fineness and uniformity of Alccofine particles play a significant role in the densification of microstructure of concrete thereby arresting the crack propagation through it effectively. The results of the experimentation on fresh and hardened properties were also positive for these combinations.
