STUDYING SOME OF THE ENGINEERING PROPERTIES OF CONCRETE CONTAINING SLAG

Abstract

The need to produce high performance concrete led the researches to try toexploit the potentialities of natural or artificial materials so as to improve theperformance of concrete . Iron furnace slag has been used as an alternative ofproportion on cement after being processed , since its main oxides are similar to those ofcement .In this investigation , the effect of slag was studied including compressivestrength and absorption of concrete in 7 , 28 days were investigated .Results demonstrated that the inclusion of 6% slag as a partial replacement byweight of cement showed superior performance over those of the other concretes ,where the percentage increase in compressive strength after 28 days relative to referenceconcrete was 19.5 % and the percentage reduction in absorption was 32 % .
