“…However, these two SFS aggregate sources reduced the split tensile strength relative to the control concrete. These findings agree with the literature in that SFS aggregates can increase [18,20,22,34,42,56,57,[67][68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84][85][86] or decrease [16,59,[87][88][89] the compressive strength and similarly increase [18,20,22,42,57,70,[72][73][74]76,79,82,85,90,91] or decrease [75,80,89] …”

“…Figure 5 shows the effect of partially replacement of coarse aggregate by slag on compressive strength at both 7 days and 28 days. Previous research has indicated that using steel slag as a replacement of cooarse aggregate will improve the compressive strength of concrete (Al-Negheismish et al, 1996). …”

This study presents an evaluation of the physical and mechanical properties and characteristics of steel slag aggregate concrete in comparison with the typical crushed limestone stone aggregate concrete. Hardened concrete consist of more than 70% aggregate due to the high demand in building construction and the increase of the amount of disposed waste material, suppliers and researchers are exploring the use of alternative materials which could preserve natural sources and save the environment. In this study, steel slag was used as an aggregate replacement in conventional concrete mixes. Steel slag which is mainly consists of calcium carbonate is produced as a by-product during the oxidation process in steel industry. Steel slag was selected due to its characteristics, which are almost similar to conventional aggregates and the fact that it is easily obtainable as a by-product of the steel industry. As a result, utilization of steel slag will save natural resources and clean environment. Furthermore, results have shown that slag aggregate has better abrasion factor and impact value than conventional aggregate. Thorough investigation of the results have indicated that the amount of increase in compressive strength at age of 7 days are much more than that of age 28 days for all types of aggregate replacement. This indicates that the added slag could work as accelerator at early age while at 28 days age, the effect is reduced. The fine slag replacement scores the highest effect.

Ceramic tiles were processed in this present work using clay mineral and steel slag. Steel slag in the range of 0 -100 wt% was added to kaolinite clay. The blended samples were hydraulic pressed into rectangular moulds, oven dried and sintered to 1200˚C. Linear shrinkage, apparent porosity, water absorption, bulk density, and modulus of rupture of sintered specimens were examined. Phases present in the sintered products were identified using X-ray Diffractometer (XRD), while the microstructural examination was conducted using Scanning Electron Microscopy (SEM). The elements present in the sintered products were identified using Energy Dispersive X-ray (EDX). Phases like quartz, wollastonite, anorthite and enstatite were identified in the sintered products. The SEM revealed crystals embedded in the glassy matrix. EDX studies detected Aluminum (Al), Silicon (Si), Magnesium (Mg) and Calcium (Ca) as the major metal ions. Results obtained showed that samples containing 20 -60 wt% steel slag have very good usable ceramic tile properties.
