Effect of Quartz sand Grains Diameter on the Mechanical Properties of Mortars

Abstract

The aim of this study is to evaluate experimentally the influence of quartz (dune sand) incorporation in the cement matrix by mass substitution at different percentages and diameters, on the mechanical properties of the mortars. Properties of the mortars were determined by flexural traction and compressive strength; the results obtained highlight the effect of the sand dune grain diameter on the mechanical properties of the mortars tested. The use of quartz (dune sand) with a diameter of less than 0.16mm improved the mechanical strength of mortars.
