Sustainable Medium Strength Geopolymer with Fly Ash and GGBS as Source Materials

Abstract

The properties of cement in the world are second only to water. As the interest and demand for concrete as a raw material
increases, Portland cement also sparked further interest. Concrete production is expected to increase from 1.5 billion in 1995 to 2.2
billion in 2010 (3% increase in annual production). In 1 ton of cement production, 1 ton of CO2 is released into the atmosphere.
Among ozone depleting substances due to unnatural climate change, the contribution of carbon dioxide to global warming is about
65%. In addition, cement is the building material that requires the most energy. Immunity to OPCs has been shown in studies
because many structures are particularly damaged and begin to decline naturally after 20 and 30 years. Efforts should be made to
develop eco-friendly construction materials to reduce greenhouse gas emissions.
