Abstract: In this work, various structural lightweight concrete (LWC) mixtures were developed by using natural lightweight aggregates, such as pumice, perlite and rice husk ash. The durability performance of these lightweight mixtures was evaluated and compared to that of concrete with normal-weight aggregates, in terms of fresh and hardened concrete’s properties. Slump, air content and compressive strength were also evaluated, along with durability characteristics, such as sorptivity due to capillary absorption, porosity and chloride penetration coefficient. The comparative analysis of the test results leaded to the conclusion that all produced lightweight concrete mixtures provide satisfactory structural strength and equivalent or even enhanced durability characteristics.
