dcterms:description
Properties of mixture of 'easte steel foundry dust(WSFD)' from Czech steel works with Portland cement were examinated. It was found that WSFDs are formed by microporous clusters of spherical particles of iron oxides, ranging in size from tens to hundreds nanometers. The content of ZnO in WSFD affects markedly the hydration of cement+WSFD mixtures regarding both solidification time and strength development. Cement+WSFD mixtures show long time strength stability and low heavy metals leaching even at WSFD content of 70 to 80 wt. The above results document the perspective of WSFD solidification and disposal and the use of this waste material as a new additive to mortars and concretes.
