Abstract

Concrete is very commonly used construction material. It is second largest material after water that is consumed on the planet. This popularity is due to the fact that it can be made by common materials and that are easily available. As consumption of concrete is very high, consumption of cement is also very high. Production of cement produces high amount of CO2. To save environment we have to find alternate solution for making concrete and partial replacement is one of the solution to reduce production of CO2.In this study, effects of waste material as partial replacement of cement on the Chloride permeability and compressive strength of concretes were experimentally investigated. The main parameter investigated in this study was M20 grade concrete with partial replacement of cement by waste material (CSW-Ceramic Sludge Waste). The percentage of replacement at the levels of 0%, 10%, 20%, 30% and 40% was examined. In this research a detailed experimental study on compressive strength and chloride permeability were carried out at an age of 7, 14 and 28 days. This investigation shows that ceramic sludge waste can be utilized as partial replacement of cement up to 20% without any loss of strength and durability of concrete.
