The effect of eggshell powder on concrete brich performance as partial replacement of cement

Concrete is one of the materials that is widely used in construction all
around the world. This material is widely used because it has several benefits such as,
more durable, energy-efficient, low maintenance, affordability, fire-resistance, excellent
thermal mass and also versatility. This study describes investigation into use of poultry
waste in concrete development by incorporating with eggshell powder. Different eggshell
powder concrete brick were developed by replacing 5-20% of eggshell powder for the
cement in order to determine the optimum percentage and observe the strength of concrete
brick to produce good cementations material for eggshell powder. The results indicated
that eggshell powder can successfully be practice as partial replacement of cement in
concrete brick production. The data collected show the cover strength development and
durability properties. With respect to the results, at 5% replacement of eggshell the strength
was higher than control concrete brick and indicates that 5% of eggshell replacement was
an optimum content for maximum strength. Furthermore, the performance of eggshell
powder concrete brick was comparable up to 10% eggshell powder replacement in terms of
durability properties with control concrete brick.
