The higher the percentage of granulated slag was, the higher the density, the elastic modulus in compression and the compressive strength of the concrete were. Dry shrinkage of the concrete increased by adding a greater amount of EAF granulated slag. Keywords Industrial by-products, electric arc furnace granulated slag, eco-sustainability, concrete
Blast furnace slag and other materials are either heated and re-melted in a cupola or electric arc furnace at 1,500 - 1,600℃, or else after being removed from the blast furnace the molten slag is kept at approximately the same high temperature and is allowed to flow out from the bottom of the furnace.
Jan 01, 2019· EAFS, blends of sodium hydroxide (NaOH) and sodium silicate (Na 2 SiO 3) solution and fine aggregate, were used for the alkali activated electric arc furnace slag (AAEAFS) mortar production.Firstly, NaOH pellets are solved in water and then were kept in laboratory conditions for 24 h to expect ending of the exothermic reactions between NaOH and H 2 O. Secondly, the prepared …
ground granulated blast furnace slag and ACI 233 (1995) provides an extensive review of slag. SILICA FUME Silica fume, also referred to as microsilica or condensed silica fume, is a byproduct material that is used as a poz-zolan (Fig. 3-7).
