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 ...

the quarry dust mixes has higher shrinkage strain compared to sand mixes. Use of fly ash in quarry dust mixes is found helpful in reducing the shrinkage of quarry dust concrete. Results indicate that quarry dust can be effectively used to replace sand and fly ash can improve the performance of concrete with quarry dust as fine aggregate.

Dust related infections have doubled according to data recorded from questionnaires (Figure 1 4). Air pollution due to quarry dust is very high during the dry season as PM 10 concentration was highest in January. Dust suppression measures must, therefore, be effectively implemented during the dry season.
