Abstract: Abstract Purpose: The paper explored the potential of Burnt clay grinding pot waste powder (BCGPWP) as a partial replacement for Ordinary Portland Cement for concrete production. Design/Methodology/Approach: Given such aim, chemical analysis was conducted on the (BCGPWP)in the Ghana Water Company laboratory. One hundred and five (105) concrete cubes were prepared and tested for compressive and split tensile strength. The mix ratio for the specimen were 0%, 5%, 10%, 15%, 20%, 25% and 30% respectively. A concrete mix ratio of 1:2:4 was used. The (BCGPWP) percentages formed part of the one-part cement. The concrete specimen was cured for twenty-eight (28) days under the shed, covered with woolen material and sprinkle with water on them every day. The compressive and split tensile tests were done on the 7, 14, 21 and 28 days. Findings: It was established that the sample contains about eight essential oxides found in Ordinary Portland Cement (OPC). The constituents were Calcium oxide (CaO), Silica oxide (Sio2), Iron oxide(fe2O3), Aluminium oxide (Al2O3), Magnesium oxide (MgO), and Sodium oxide (Na2O), Potassium Oxide (K2O) and Sulphur Oxide (SO3). On the 28th day of testing, the control specimen had 17.05 N/mm2, 5% replacement had 16.53%, 10% replacement also recorded 16.55 N/mm2 with 15% declining to 7.46 N/mm2. Twenty percent went up to 17.57 N/mm2 with 25% registering a compressive strength of 15.18 N/mm2 while the 30% recorded 15.35 N/mm2. Implications/Research Limitations: The study could not ascertain the type of clay used for the production of the traditional burnt clay grinding pot. Again, the study could not unearth the temperature at which the pot/pot waste were subjected to before it came out of the fire. Practical Implications: The usage of Burnt clay grinding pot waste powder as a partial replacement for Ordinary Portland Cement for concrete production will help to reduce the cost of construction. Social Implications: It will help in improving the environment by recycling waste into construction materials for use. Originality/Value: The use of burnt clay grinding pot waste powder as a partial replacement for Ordinary Portland Cement for concrete production is a novelty in construction material development.
