While the interaction between the cement-based binders and different types of fillers is described sufficiently, the behaviour of composites, containing gypsum and any type of filler was studied less frequently and studies focused on the interaction between the composite binder and filler are rare. We studied ternary binder composed from gypsum, lime and silica fume in combination with several types of fillers (sand, expanded perlite, expanded clay and waste polyurethane). The strength of the composites was measur...

The massive depletion of natural resources, together with the inefficient use of end-of-life materials, results in the generation of vast amounts of waste. The waste material recycling poses a challenge for the present generation and alteration of current material streams needs to be reconsidered to mitigate the consequent environmental burdens. The construction industry produces several millions of tons of brick debris which remain landfilled or, at the best, are used as a substitute for natural aggregates. Howev...

Heavy metals ions can be removed from industrial wastewaters by numerous methods, such are precipitation, electrolysis, electrodyalisis etc. Sorption, i.e. adherence of a dissolved specie on solid sorbent, may be a cost-effective alternative to these conventional methods, in case a low-cost material is used as sorbent. Heavy metals are well sorbed by zeolites, clay minerals, char coal, carbon nanomaterials or numerous biopolymers. In this research, waste ceramic was used as sorbent for heavy metals (Cu, Pb, Zn).
