  The purpose of this study was to optimize the relative proportions of the input ingredients of clay, sand and water utilized in a formulation by a leading hollow core clay brick manufacturer in Trinidad as a possible solution for the incidence of production of defective products. The influence of incremental changes in the proportions of ingredients on important physical characteristics of clay bricks such as compressive strength, extruded surface finish, flexural strength, shrinkage, density and extrusion pressure and the rheological properties of dynamic modulus (G*) and phase angle (δ) were investigated before the firing stage. The optimum formulation was found to be the addition of an additional 5% clay content to the manufacturer’s original mixture utilizing with a water/clay ratio of 16% composition. Further research is recommended on optimization of the firing process by testing fired properties with these optimum ingredients.
