ABSTRACT
The geopolymer type binders could be an alternative binders to cementitious binders. These are materials doped with various alkali precursors. The role of these precursors is to initialize and propagate polymerization of the matrix, to trigger solidification. Various precursors behave differently in the matrix. They affect ongoing processes, especially solidification of dispersion, rate of polymerization, final strength of solidified material [1], etc. Therefore, in this work the effects of the aluminum modified precursor on some parameters of castings made from lime-silica slag dispersion and thisrecursor were experimentally studied. Main parameters studied were volume hanges during solidification and final strengthof castings after 7 days of curing. In this work original results are presented, discussed and processed into table and graphical form.
