Abstract

This research investigates the influence of untreated sugar cane ash (SCA) as a partial replacement for cement on the setting time and compressive strength of concrete mixes. The SCA was introduced at replacement levels of 0%, 5%, 10%, 15%, and 20% by weight of cement. Specimens were tested at 7, 14, and 28 days of curing. Results showed a slight delay in setting time and a marginal reduction in compressive strength with increasing SCA content. However, the concrete maintained adequate performance up to 10% replacement, satisfying ASTM pozzolanic criteria. The 5?10% replacement range was found to be optimal, offering a balance between performance, cost efficiency, and environmental sustainability. The findings indicate that untreated SCA can be used in non-structural and light structural concrete applications to reduce cement dependency.
