Pumice Lightweight Aggregate has a long track record of quality and performance. Since its development in the early nineteen hundreds, Pumice structural lightweight concrete has been used extensively in high-rise buildings, commercial buildings, hospitals, schools, government housing and major shopping centers.

Keywords : Pumice; Lightweight Aggregate, Bulk Density, Grading 1.0 Introduction In concrete production aggregate is the cheaper material as compared to cement and maximum economy is obtained by using as much aggregate as possible. Aggregates .

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 ...

Pumice was used as lightweight aggregate by the Romans more than 2000 years ago to construct such buildings as the Pantheon. Pumice results from volcanic activities and is formed by expansion of gases in rapidly cooling lava. Pumice is available in few countries
