The physical and chemical properties of marine clay at Olotu in Ilaje local government of Ondo State, Nigeria were investigated. Some of the physical properties investigated include plasticity index, linear shrinkage and firing characteristics (firing colour, shrinkage percentage, and water absorption capacity). The physical properties were determined using X-ray diffractometry method. The chemical composition was determined using Atomic Absorption Spectroscopy (AAS) method. All tests were carried out according to procedures specified by relevant British and American Standards. It was established that the physical and chemical properties were adequate to qualify it as pozzolanic material for cement production when compared with other pozzolanic materials and measured against relevant standards. The cement produced was tested for compressive strength and setting times and the results confirmed the appropriateness of the use of the clay as a pozzolana.
