A B S T R A C T Steel slag is produced as by-product during the oxidation of steel pellets in an electric arc furnace. This by-product can be broken down to smaller sizes to be used as aggregates in asphalt and concrete. In the current research, locally produced steel slag in Egypt was used as a replacement of the ... إقراء المزيد

ABSTRACT The current research aims to investigate the residual compressive strength of normal, high and ultra-high strength concrete containing local electric arc furnace steel slag (eafss) as a replacement of the used natural aggregate after exposure to elevated temperatures. Specimens of thirty concrete mixes with different intended compressive strengths were prepared and after 28 days the compressive strength was obtained ... إقراء المزيد
