Abstract

The increase in agricultural waste such as African locust bean pod have resulted in endangering the life of plants and animals. Researchers have found out ways that this environmental pollution can be of positive relevance by recycling the waste to be re-used or reduce to ensure a cleaner and healthier environment. African locust bean pod was ashed and the pozzolanic properties were investigated. The pod was dried, blended and ashed in a furnace at 500°C for two (2) hours; different analysis was carried out on the ash obtained to prove the pozzolanic properties, such as sieve analysis to determine the particle size distribution; reaction of calcium hydroxide with the ash in relation to time which proved that pozzolanic reactivity increases with time, comparison of hydration of Portland cement with ashed locust bean pod mixture and compressive strength test.
