    The influence of blast- furnace slag hydration products on micro cracking of concrete

  • Original language description

    New hydration products of ground granulated blast-furnace slag are formed during the hydration process of Portland slag cement concrete. Spatial distribution of microcracks in concrete is related also to newly formed slag hydrates. The chemical composition of hydration products is very variable and unstable. The Si/Ca ratios rise in hydration products near the unhydrated slag core significantly. There is also a certain increase of Mg and Al content in the central parts of hydration rims. The amount of microcracks was reduced in concretes with a lower content of vitreous fraction where the slag basicity was high. Neoformation of hydration products is accompanied by volume changes which can lead to concrete microcracking.

    Vliv hydratovaných produktů vysokopecních strusek na praskání betonů

  • Czech description

    Hydratační produkty vysokopecní strusky se tvoří během hydratačního procesu portlandského struskového cementu. Hydratace strusky je provázena morfologickými změnami a snižováním kapilární porosity C-S-H produktů. Přítomnost a rozmístění mikrotrhlin v betonu souvisí s chemickým složením hydratačních produktů strusky. Permeabilita je jedním z hlavních faktorů, který ovlivňuje výslednou trvanlivost betonu.
