STUDY THE EFFECT OF ADDITION GLENIUM 51AND SILICA FUME ON THE MECHANICAL AND PHYSICAL PROPERTIES OF ORDINARY PORTLAND CEMENT

Abstract

This research includes a study of the effect of adding Glenium 51 polymer and silica fume 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 silica fume were added in different weight ratios as a percentage of the cement weight, and the results showed increase in compressive strength, flexural and tensile strength. All experiments were conducted with different temperatures of 7C°, 20C°, 55C° respectively to demonstrates the effect of different temperatures 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 the temperature of 20 C° for the moulds and there is increase in the compressive, flexural and tensile strength after adding the additives in all temperature. The values of the compressive and tensile strength used the standard specimens at the age of (2& 28 ) days.
