Comprehensive Study on Fresh and Hardened Behaviour of Sintered Fly Ash Aggregate based Lightweight Self-Consolidating Concrete

The goal of this study is to see if sintered fly ash aggregate (SFA) can be used as a partial replacement for natural coarse aggregate (NCA) in the creation of long-lasting structural lightweight concrete (LWC). In this case, natural aggregates are partially replaced by sintered fly ash aggregates, with 0 percent, 10%, 15%, 20%, 25%, and 30% of the volume being replaced by sintered fly ash aggregates. To find out how well it performs, In the current study, 40MPa concrete was produced and different Fresh characteristics were tested (Viz., L-Box and T500) Compressive strength and split tensile strength are examples of mechanical characteristics, as are durability attributes (like water absorption test and permeability). According to the findings, replacing sintered fly ash aggregates has a detrimental impact on fresh characteristics. However, the combination with 20% sintered fly ash particles has excellent strength and durability.
