The lightweight aggregate is an aggregate that weighs less than the usual rock aggregate and the quarry dust is a rock particle used in the concrete for the experimentation The significant intention of the proposed technique is to frame a mathematical modeling with the aid of the optimization techniqu The mathematical modeling is done by minimizing the cost and time consumed in the case of .
Normal weight aggregates were replaced by LECA with size fractions of 4–8 mm and 8–12 mm at three different weight fractions such as 60%, 80% and of the coarse total aggregate weight of concrete The mixtures were varied by replacement of natural coarse aggregate by LECA up to by weight
