Physic-Mechanical Properties of Desert Sand Based Mortars with Additions: a Review

EasyChair Preprint 6856

Abstract

In recent years, the depletion of natural aggregate deposits and the difficulties in finding new quarries have made it necessary to look for other sources of supply. The reclamation of sand from a desert dune is now seen as a solution for the future in order to respond to the deficit between production and consumption and the exploitation of natural resources in the southern regions of Algeria. The purpose of this synthesis is to present a summary of some research work reported in the literature on the usefulness of the use of desert dune sand in the mortar and concrete industry. Several researchers have developed cementitious materials based on dune sand and additions such as rubber, Rice husk ash, olive kernel shell, grilled copper slag, glass, vegetable fiber, carbon fiber, polypropylene fiber and polyester fibers, in order to improve certain physic-mechanical characteristics of mortars and / or concrete. It has been revealed that the introduction of additions / fibers into a cementitious composition originating from desert dune sand improves mechanical strength such as Rc and Rt; and also decreases capillary shrinkage and absorption, which has recently improved the durability of cementitious structures.
