Stabilization of compressed earth block clayey materials from Adrar (Algeria) by lime and crushed sand

Abstract: The objective of this article is to determine the physical and mechanical properties of stabilized compressed earth bricks (SCEB), made from a mixture of clay with crushed sand, and stabilized by lime. In this study, we first examine the identifying properties of raw materials. Then an experimental study was conducted with cylindrical test pieces of a mixture of clay and crushed sand prepared by the addition of lime and statically compaction, to study the physical and mechanical characteristics of the mixture. The experimental study shows that for use as a building material, the clay mixture with 30% crushed sand and stabilized with 4% and 6% lime is the optimum mixture for as a stabilized compressed earth bricks
