Cement replacement for concrete mixture containing 4% pyrolysis carbon black

Abstract

Abstract: This research aims to replace the cement for concrete mixture containing 4% PCB and to study the concrete properties as compression, slump, friction and absorption tests. The importance of this research is to know the possibility of reducing the amount of cement in concrete mixtures containing 4% PCB with a focus on maintaining the mechanical properties of the concrete mixture. Key words: Concrete, PCB,and CR :cement reduction
