Abstract
nGeopolymer concrete (GPC) is regarded as the successor to traditional concrete as it eliminates the requirement for conventional Portland cement during its manufacturing process, hence decreasing CO2 emissions. This study employed Cenosphere, which are lightweight fine materials, to partially substitute the volume of sand in GPC. Cenosphere was utilized in proportions of 20%, 40%, 60%, and 100%. This experiment examined the fresh and hardened characteristics, durability against freezing and thawing, and ability to withstand impact strength of cenosphere admixed the concrete. The findings demonstrated that the utilization of Cenosphere as a substitute for sand in GPC resulted in marginal enhancement in compressive strength across all time periods and replacement ratios. When comparing the control GPC mix to the use of 60% Cenosphere, there was an increase in compressive strength of up to 4.7% at 28 days. The GPC containing 60% cenosphere exhibited the highest split tensile strength. The slump of GPC is reduced as the proportion of Cenosphere increases. This study found that the application of freezing-thawing cycles (up to 30 cycles) did not have a noticeable impact on the compressive strength of GC. The addition of Cenosphere to GPC resulted in a reduction of up to 25% in impact resistance compared to the control GPC. The study demonstrates that Cenosphere can be incorporated into GPC as a partial replacement for fine aggregate, in order to create a new type of GPC suitable for structural purposes.
