As the manufacture of one tonne of cement generates about 1 tonne of carbon dioxide, the environment could be conserved by using less cement through partial replacement of PFA and GGBS. On the other hand, the use of GGBS and PFA as partial replacement of cement enhances the long-term durability of concrete in terms of resistance to chloride

Mar 01, 2019Alternative binders, such as fly ash (FA) and ground granulated blast-furnace slag (GGBS), can partially replace cement, and production of these binders emits less CO 2 than production of cement. On average, the possible reduction in emissions is around 27 per cent from current levels. However, the supply of these alternatives is limited.

REPLACEMENT CONCRETE: MATERIALS AND APPLICATIONS
Replacement concrete repairs are made by bonding new concrete to the repair areas without the use of a bonding agent or Portland cement grout. Because the defective concrete is being replaced with high quality concrete very similar to the surrounding concrete, the repair is compatible in thermal expansion and in other physical and chemical

Supplementary Cementing Materials
Supplementary cementing materials (SCMs) contribute to the properties of hardened concrete through hydraulic or pozzolanic activity. Typical examples are fly ashes, slag cement (ground, granulated blast-furnace slag), and silica fume. These can be used individually with portland or blended cement or in different combinations.

So how can we make cement, and therefore concrete, more sustainably? We can add other materials that produce less CO 2 to the mix – even if some Portland cement still has to be used to drive the important setting reaction. One example is a steel production by-product called ground granulated blast-furnace slag (GGBS), which can be incorporated in varying quantities

QA: Why cement emissions matter for climate change
What is cement? Cement is used in construction to bind other materials together. It is mixed with sand, gravel and water to produce concrete, the most widely used construction material in the world.Over 10bn tonnes of concrete are used each year.. The industry standard is a type called Portland cement.This was invented in the early 1800s and named after a building stone
