ABSTRACT
Ordinary Portland cement is increasing in market price yearly, not making it as affordable as it used to be. Using agro waste such as plantain peel ash as partial replacement for cement (due to the presence of resins which serves as a binder) can help bring down the cost of concrete, especially for local use concrete in buildings and light weight concretes.
The plantain peel was obtained from the Ekosodin community, Benin city, Edo state. Commercially available ordinary Portland cement, fine aggregates, and coarse aggregates, were purchased for the experiment. The fine aggregate was sieved in accordance with ASTM C136. A mix design of 1:1:2 was used to achieve a standard compressive strength of M25. A total of 36 cubes (cube size of 100mmx100mmx100mm) was casted; 9 cubes each for 0%, 5%, 10% and 20% of partial replacement of cement with the plantain peel ash. The cubes were tested for compressive strength for 7days, 14days and 28days.
After the experiment, it is found after that at 20% replacement with RPPA that a similar compressive strength can be achieved.
