Abstract:

 The objective of this study is to characterize a lightweight aggregate expanded in laboratory.
Identified by physical, chemical, mineralogical and heat treatment, raw clay verified a set of conditions for
the manufacture of lightweight aggregates. Smectite, illite and kaolonite were present. Expanded clay
aggregates were then produced in the laboratory following a specific manufacturing process. The effect of
temperature on the expansion properties of aggregates was studied. The properties obtained are comparable
to those available in the commercial sector. The pellets were used in a concrete mix. The compressive
strengths were determined at 3, 28 and 90 days with a cement water ratio 0.5 and a cement content of 350
kg/m3. The results of the mechanical behavior study seem to be very similar to those required by the relevant
standards for lightweight concrete. The study aimed to add value to the Tunisian clay which is not generally
considered a natural resource for industrial development to meet the important needs of the construction
industry and public works.
