Abstract
The high cost of cement is a major drawback in concrete usage. This research aimed at determining the strength charac t eristics of concrete incorporating calcined earthworm cast as partial replac e ment of cement . The objectives were to obtain the optimum percentage of calcined earthworm cast that can be used to replace cement in a given concrete mix , and to ex amine the physical I chemical properties of the calcined earthworm cast. Percentage replacement of cement with the earthworm cast was done at 0, 10 , 20, 30% respectively and tests were carried out on fresh and hardened concrete. The results showed that while the initial and final setting time of the concrete containing earthworm cast increased with the increase in earthworm cast content, the compressive strength decreased with increase in ca lcin ed ea rthworm cast replacement . It was concluded that a partial replacement of not more than 30% of cement with calcined earthworm cas t will suffice .
