Effect of adding Glenium 51 and styrene-butadiene rubber on mechanical and physical properties of Ordinary Portland cement

Abstract

This research includes a study of the effect of adding Glenium 51 polymer and styrene butadiene
rubber on the mechanical and physical properties , which included compressive , flexural and
tensile strength of cement mortar and comparing the results with reference cement mortar .
Glenium 51 and SBR were added in different weight ratio as apercentage of the cement weight,
and the results showed increase in compressive strength, flexural and tensile strength.
All experiments were conducted with different temperture of 7C°, 20C°, 55C° respectivly
to demonstures the effect of different temperture on cement strength and the polymers behaviour
and the results showed that the compressive ,flexural and tensile strength of the cement mortar
reached its maximum value at temperture of 20 C° for the molds and there is increase in the
compressive , flexural and tensile strength after adding the additives in all temperture .The values
of the compressivr and tensile strength used the standard specimens at the age of (2& 28 ) days
