20-06-2019· Geopolymer concrete (GPC) has been researched during the past few decades as an alternative to sustainable construction materials, which can minimize CO 2 emission for its use of industry by-products. Past researches on GPC show that it can be suitable for the structural applications, with a workable slump, and comparable grade of strength to ordinary Portland cement concrete.

It is a more environmentally friendly alternative to conventional Portland cement. It relies on minimally processed natural materials or industrial byproducts to significantly reduce the carbon footprint of cement production, while also being highly resistant to many common concrete durability issues.. Geopolymer cements exist which may cure more rapidly than Portland-based cements.

Geopolymer concrete was produced by activating fly ash with a highly alkaline solution of sodium silicate containing 16.45% Na2O, 34.35% SiO2 and 49.20% …

What is a geopolymer? In the 1950s, Viktor Glukovsky, of Kiev, USSR, developed concrete materials originally known under the names "soil silicate concretes" and "soil cements", but since the introduction of the geopolymer concept by Joseph Davidovits, the terminology and definitions of 'geopolymer' have become more diverse and often conflicting.

Safe and sustainable geopolymer concrete. A basic ingredient of concrete, ordinary Portland cement (OPC) is the most commonly used type of cement for construction of buildings and infrastructure. However, OPC production is responsible for 5-8 % of all man-made carbon dioxide (CO2) emissions across the globe.

01-04-2020· Geopolymer concrete has a distinguished property of being reduced the use of vibration and cement. • The main function of developing geopolymer concrete is to reduce the emissions of CO 2 in the atmosphere.. The rate of strength development of geopolymer concrete is mainly relied on the source of material and alkaline activators.

E-Crete TM. E-Crete™ is Zeobond’s proprietary geopolymer technology product. Consisting of fly ash, the by-product of burning coal at a power station, and slag, the by-product of steel manufacturing, E-Crete™ reduces the embedded CO2 of concrete by at least 60% compared to Ordinary Portland Cement (OPC) based concrete.

Geopolymer concrete is thus believed to be suitable for structural applications. With regard to safety assessment and design of concrete structures, it has been recognised that the fracture properties of concrete need to be considered in structural design (Hilsdorf and Brameshuber, 1991).
