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 techniques. The mathematical modeling is done by minimizing the cost and time consumed in the case of

It has also been reported that the reduction in the compressive strength of quarry dust concrete was compensated by the inclusion of fly as into the concrete mix. Reddy and Reddy, 2007 reported an increasing compressive strength by use of rock flour as fine aggregate instead of river sand.
