Sažetak
Utilizing a high volume of fly ash as a replacement to cement in concrete is not widely practiced because of less strength gain in the earlier days. The fly ash at a replacement rate of 50 % was used in the C25/30 grade concrete to develop the sustainable HVFA concrete. The addition of 50 % of fly ash in the concrete reduces the heat increase and embodied energy with enhanced mechanical properties and structural behavior. The load carrying capacity of the beam was increased by 57 % at 7 days, along with 53 % reduction in ultimate deflection with the addition of only 2.5 % of accelerator.
