This experimental study introduces an organic wasted material, which hopefully can be another solution besides other expensive chemical-based additives. The study intends to investigate the effect heating temperature on charcoal powder, which is originated from the coconut-shell waste material, related to its ability in enhancing cement strength. Six samples with different additive concentration should be prepared before initiating the strength test. the strength test principally follows the bi-axial loading test procedure, where each sample will be burdened by a certain amount of the load force until failure condition was reached. The recorded pressure where the failure occurs will be treated as maximum load, which is needed for determining compressive strength and shear-bond-strength values. Those parameters should be in refer to respectable standard in the oil and gas industry. Results from the strength test clearly indicate that higher heating temperature yields to a cement with a high strength. The optimal heating temperature has reached for a sample with 700°C charcoal powder. It is a potential opportunity in increasing the economic value of the waste material.
