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 ...

Ultrafine GGBS and calcium nitrate as concrete admixtures ...

X-ray diffraction studies on powdered concrete showed that the amount of silica in the concrete increases with the introduction of GGBS. Calcium hydroxide was converted to calcium silicates. Ultrafine GGBS reduced the workability and water absorption and increased the compressive strength of the concrete (18%) and the bond strength of the steel rebar (45%).

Since most chemical admixtures perform well in plain Portland cement mixtures and in Portland cement and fly ash concrete, it is not surprising that they provide similar performance when used in slag concrete. Since there is little or no carbon in GGBFS, concrete …

Concrete Admixture (Chemical and Mineral Admixtures)

CONCRETE ADMIXTURES • Admixtures are material other than cement, aggregates & water that are added to concrete either before or during mixing to alter its properties & performance in fresh (workability, setting time etc) and hardened state (strength, durability etc.) Concrete admixtures are generally divided into 2 types i.e., 1.

FA, GGBFS mineral admixtures as partial replacement of the OPC using in the SCC are becoming increasingly common in civil engineering structures. Utilizing FA, GGBFS for the production of the SCC can not only reduce total material costs of the SCC, but also result in considerable benefits to the environment (Ondova et al., 2011).

Mineral Admixture - an overview | ScienceDirect Topics

Some researchers reported that GGBFS concrete mixes exhibited 20–50% greater slumps than ordinary concrete with the same w/c content ratio (Duos and Eggers, 1999). Meusel and Rose (1979) reported that when the GGBFS content is increased, there is an accompanying increase in slump in nonsuper plasticized concrete.
