Preparation and Properties of Sustainable Concrete Using Activated Sludge of Industrial By-Products

Abstract

Industrial sludge byproducts contain CaO, SiO2 , Al2O3 , etc. When industrial sludge is used in ready-mixed concrete, the performance of the concrete can be enhanced due to the hydration reaction. In the present study, activated sludge was used to prepare ready-mixed concrete, and its durability performance was evaluated. Once the activated sludge was used, the durability of the concrete improved. Therefore, it is suggested that activated sludge can be used in concrete mix as an admixture.
