In this work, we are interested in the making of a lightweight concrete based on pozzolanic aggregates, the use of pozzolan as aggregates is in order to promote a natural product is abundant in nature which is natural pozzolan. In general, this work aims to familiarize the use of lightweight concrete in Algeria the benefits they present. Knowing that light aggregates are not available hence the use of natural pozzolanaightweight concrete, pozzolan, mechanical characteristic, light aggregates, resistance.
