Snail and clam shells are waste materials from Snail and Clam after removing the edible part. They are often dumped as waste to the environment and causes environmental pollution. This research aimed at comparing admixtures from these waste shells as alternative to cement. Snail shell, Clam shell and Snail/Clam shell mixtures were used as partial replacement of cement in this work because of their pozzolan nature. The result from the experiment carried out showed that Snail/Clam shell mix mortar mould had better comprehensive strength compared to snail or clam shell mould respectively at partial replacements by weight (10-30%). The comprehensive strength of the mortar mould also decreases with increase shell ash content mixed with the cement. Maximum partial replacement by weight of cement with snail shell ash was obtained at 20% with comprehensive strength of 20 N/mm². Clam shell ash was at 25% with comprehensive strength 30 N/mm² while Snail/Clam shell ash mixture had comprehensive strength of 38 N/mm² at partial replacement of 25%. The initial and final setting times for the blended cement paste increases as the shell ash replacement increases with Snail shell ash blended cement having higher initial and final setting, followed by Snail/Clam mixture blended cement.
