GGBS in concrete improves resistance to sulfate attack due to the reduction of Ca (OH) 2 and lower the C 3 A content. GGBS in concrete reduces the diffusion of chloride ions and hence improves the resistance against corrosion. The total shrinkage of concrete containing ground granulated blast furnace slag (GGBS) was lower than Portland cement.
Published 24 August 2015. Materials Science. Concrete is a mixture of cement, fine aggregate, coarse aggregate and water. Concrete plays a vital role in the development of infrastructure Viz., buildings, industrial structures, bridges and highways etc. leading to utilization of large quantity of concrete. On the other side, cost of concrete is ...
Tata Steel, one of the acclaimed GGBS manufacturers in India, has earned another feather in its cap with its GGBS being awarded the 'Green Pro Certification' for its varied applications, and usage as a long-lasting and viable eco-friendly building material in India. The product, apart from offering environmental benefits, is also cost ...
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 calcium silicate hydrates (CSH) which is …

Ground granulated blast furnace slag (GGBS) was employed as the main component of an alternative binder. Ground agricultural gypsum and construction-grade hydrated lime were used as activators in the proportions of 0.88:0.10:0.02 (GGBS:gypsum:lime) by mass as previously discussed (Oliveira et al., 1999).Sisal (Agave sisalana) field by-product was selected from a …
Data from the only study on natural carbonation ( Frignione and Sersale, 1994) show that the carbonation depth of concrete made with 70% GGBS after 3-year exposure reduces from 1·5 mm to 5·0 mm for every increase of 100 m 2 /kg GGBS fineness, with an increase of 1–3% in its sulfur trioxide (SO 3) content.
Green and Gracious Builder Scheme. The Green and Gracious Builder Scheme (GGBS) was introduced in 2009 to raise the environmental consciousness and professionalism of builders. It is also a benchmark of a builder's corporate social responsibility to the environment and public during the construction of projects. It aims to:
Saturday, 12. June 2004. Dies ist die Website von GGBS, dem Regionalkomitee Gemeinden Gemeinsam Biel/Seeland. Während mehr als zwölf Jahren unterhielt unser Verein eine Partnerschaft mit der mazedonischen Region Kruševo. Wegen akutem Mangel an aktiven Mitgliedern wurde auf Ende 2008 die Auflösung des Vereins beschlossen.
Because GGBS has low embodied CO 2, it allows designing concrete mixes for sustainable construction. The manufacture of GGBS requires less than 20% of the energy and produces less than 10% of the CO 2 emissions compared to Portland Cement production. GGBS is a sustainable alternative for Portland Cement in the production of: ready-mix concrete.
The characteristic of GGBS was examined using particle size analyzer, X-ray diffraction (XRD) and chemical analysis tests. Table 1 shows the physical and chemical properties, whereas Figs. 1 and 2 show the particle size distribution and XRD test result of the GGBS respectively. The average particle size of GGBS was 9.2 μm compared to 14.6 μm for …
GGBS (Ground Granulated Blast-furnace Slag) is a cementitious material whose main use is in concrete and is a by-product from the blast-furnaces used to make iron. Blast-furnaces operate at temperatures of about 1,500°C and are fed with a carefully controlled mixture of iron ore, coke and limestone. The iron ore is reduced to iron and the ...
