English Abstract

Marble dust and brick waste materials taken from demolition of buildings create serious environmental problems so the main aim of this paper is to evaluate the potency of employing mixed (marble-dust and brick-powder) waste materials altogether as partly replace of cement and the fine-aggregate respectively in the composition of concrete which were mixed with a ratio of (1:2:4) and (W/C) ratio equal to (0.45).

In this study the cement has been replaced by marble dust waste in the proportion of (0%,5%, 10%, 15%, 20%, 25% ) and fine aggregate replaced by waste brick powder in the proportion of (0%,5%,10%, 15%,20%,25%) by weight of concrete mix simultaneously .

In this paper the (compressive , flexural and split tensile) strength of the concretes mixtures were specified .

The main results of this paper appeared that the (cement and sand) can be partially replaced by( marble- dust and brick- powder) in the concrete mixture and it has achieved the optimum percentage of replacement by (20)%.

So that utilization of construction waste is required in an attempt to equilibrium between the construction request and environmental sustainability.
