The effect of sodium silicate and sulphuer "from mishraq "in strength of concrete

الملخص EN

The present work deals with was carried out sake of improving some physical properties of this material by means of adding sodium silicates, Sulpher "from Mishraq ", in small different percentages, has improved the quality of concrete via the increase of its compressive and the mortar tensile strength the study showed that the addition mixture of sodium silicates, Sulpher Causing an increase in the Compressive and the mortar tensile strength.

When comparison was carried out with reference concrete mix.

All the above work was carried out at different ambient temperatures of 8, 30 and 50˚Crespectively sake for the of showing the effect of different temperatures on the concrete compressive strength All the results indicated that the concrete Compressive strength and the mortar tensile strength reached maximum at 8˚C.

The values of the concrete Compressive strength and the mortar tensile strength refer to standard specimens (Cubes) at the age of 7 and 28 days.
