In the present work the geopolymerisation of blast furnace slag (GGBS) under varying conditions is being investigated. The experimental comprises the following parts: i) dissolution of slag in alkaline media and the investigation of the effect of the alkali ion (K or Na) on the dissolution of Al+3 and Si4+, ii) synthesis of slag based geopolymers and the investigation of the effect of the Si/Al ratio and the kind of alkaline ion on the development of the compressive strength and iii) characterization of geopolymers by means of XRD, FTIR and SEM/EDS measurements. As it is concluded, blast furnace slag geopolymers exhibit high compressive strength, with the maximum being 112.7±2 MPa. The Si/Al ratio of the starting material is found to affect strongly the development of the geopolymer compressive strength. The microstructure of slag–based geopolymers and the incorporation of Ca in the geopolymer matrix are also discussed.

The microstructure of a clay ceramic added with blast furnace sludge, a residue generated at integrate steel making plants, has been analyzed. This analysis was performed by means of optical microscopy and scanning electron microscopy coupled with energy dispersive spectroscopy. The green clay body was added with 5 and 10 wt% of blast furnace sludge. A pure clay body was also considered as reference. These clay bodies were fired at 750°C and 950°C. The results indicated that the ceramic microstructure is non-uniform with both residue particles and pores dispersed throughout the clay matrix. Microcracks are also observed as a consequence of weak adhesion of the residue to the clay. At the higher firing temperature of 950°C the microstructure displayed a smoother surface due to the formation of low melting phases.
