Abstract

Abstract In the present work, a composite material is developed using stone dust and ceramic waste. The stone dust and ceramic waste are the replacements of natural sand and stone respectively. The developed composite is tested for various mechanical testing to know the strength under compression, flexural and shear. Seven different types of samples were casted by varying the stone dust from 0% to 100% in the interval of 20%. The ceramic waste aggregate was kept constant at 20% in all the samples except in conventional concrete sample. The workability of the mix was improved by adding PCE based superplasticizer. The results showed that the replacement of stone aggregates with ceramic waste alone tends to reduce the mechanical strength of the concrete. As compared to conventional concrete, compressive and flexural strength of the S0C20 sample (i.e. 0% stone dust and 20% ceramic) is slightly reduced. The maximum strength, was obtained in S40C20 sample (i.e. 40% stone dust and 20% ceramic) for compression, shear as well as in flexure. Therefore, the natural sand and stone aggregates can be partially replaced with stone dust and waste ceramic aggregates respectively for the manufacturing of a composite material (i.e. concrete) in an optimized percentage.
