  • Granulated Blast Furnace Slag an overview

    The blast furnace cement (CEM III) in Table 4.1 is so-called low early-strength cement, indicated by L. Low early-strength CEM III cement conforming to the requirements in Table 4.2 can also be designated sulphate-resistant common cement. Common cement with blast furnace slag often has LH in its designation, which implies low heat of hydration.

  • Ground granulated blast-furnace slag Wikipedia

    Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.Ground-granulated blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing

  • Blast-furnace slag as a mineral admixture for concrete

    The use of separately ground blast-furnace slag, added at the mixer as a replacement for a portion of the p o r tland cement, has gained increasing acceptance in recent ye a r s .
