Cement is the major agent in the process of construction act as a glue in material and construction industry. This paper presents the effect of copper powder when replaced 1%, 3% and 5% of the cement amount in the concrete cube. Experimental setups were carried out to study the transitions that appears after the testing process and the concrete cube features noticed in the observation step, when copper powder react with cement, how it will transform the concrete physical characteristics? This research provide that natural additives when combined or replaced with cement bring changes in the strength and mechanical properties of the concrete from the experimental results. The morphology images of the cement paste containing 1% of copper powder concerned while using Field Emission Scanning Electron Microscopy(FESEM) and its chemical composition was also noticed by using X-ray Diffraction(XRD) to clarified the changes occurred on the concrete with and without additive. Crack patterns on the concrete cube were explain during failure and the time of first crack also been taken during the experimental process. Apart of, compressive strength of the concrete were observe.

A Novel Method on the Effect of Natural Additive on Cube Crack Morphology
