Sustainability Ground granulated blast furnace slag „GGBS‟ is one of the „greenest‟ of construction materials. Its only raw material is a very specific slag that is a by product from the blast furnaces manufacturing iron. Manufacturing of „GGBS‟ utilises all of the slag and produces no significant waste.
Sustainable development has been defined as development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
Ecocem GGBS is produced by drying and grinding the GBS at our milling plant in Dublin. CHEMICAL COMPOSITION The rate of vitrification means that the glass content of Ecocem GGBS is greater than 95%. (measured by X-ray diffraction) ensuring highly *AI 2
The quality of GGBS is in compliance with GB/T 18046 for grade S95 and BSEN 15167-1. It is widely used for construction works in Guangdong, and has also been used for the

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: Set standards for gracious practices.

This paper concludes that whilst global supplies of GGBS must continue to be fully utilised to reduce overall clinker demand, any local increase in the amount of clinker substituted with imported GGBS is unlikely to decrease global emissions. GGBS should continue to be used where required technically. Beyond this, it may still be specified
This paper reviews the global availability of ground granulated blast furnace slag (GGBS), concluding that whilst global supplies must continue to be fully utilised, any local increase
The grinding process takes account of mean particle size, grading (particle size distribution), fineness and the particle shape in order to ensure that when used in concrete performance is maximised. Typically, GGBS is ground to a specific surface area of 450-550 m 2 /kg, similar to that of cement.
GGBS is an acronym for Ground Granulated Blastfurnace Slag, a by-product from the manufacture of Iron. Ecocem GGBS is used in combination with Portland cement to produce superior longer lasting concrete. A replacement rate of up to 70% is permitted by I.S EN 206-1. Ecocem GGBS is an industrial by-product that is diverted from landfill and up

It has a density of 2,830 kg/m 3, which is about 10% lighter than OPC. Compared to OPC, its seven-day activity index is about 60%, whereas its 28-day activity index is at least 75%. Its chemical compositions are as depicted in Table 1, from which it can be seen that the CaO content is 43.4%, the SiO 2 content is 34.5%.
