About this site

Jun 10, 2018  Portland cement is one of the most manufactured materials in the world. Over 3 billion tonnes of cement were manufactured in 2012 (Imbabi et al., 2012), and global demand is expected to increase due to the rapid infrastructural development of emerging economies (Schneider et al., 2011, Benhelal et al., 2013).Indeed, global cement production is forecast to reach 3.7–4.4 billion tonnes by

Jul 18, 2019  Fly Ash is mixed with lime and water to make it strong and durable, similar to conventional cement. Use of fly ash in Ashcrete makes it an environment friendly alternative, since it can replace cement which in turn leads to reduced CO2 emissions. Moreover, 25% of cement can be replaced using high-volume fly ash concrete.

Abstract Concrete for construction has traditionally been based on an Ordinary Portland Cement (OPC) binder. Geopolymers, an alternative binder based on fly ash (a fine waste collected from the emissions liberated by coal burning power stations) that is activated by an alkaline activator, have potential to lower the significant carbon footprint of OPC concrete.
