Geopolymer is known to have many structural and nonstructural benefits, but the attractive characteristic of this novel material is that it depends essentially on a byproduct from different industries, and the use of Portland cement is absent. This c

Tire rubber waste is globally accumulated every year. Therefore, a solution to this problem should be found since, if landfilled, it is not biodegradable and causes environmental issues. One of the most effective ways is recycling those wastes or usi

The manufacture of ordinary Portland cement (OPC) produces a lot of CO2 in the atmosphere. Researchers have recently focused on exploring the behaviour of geopolymer concrete (GPC) as an alternative to Portland cement concrete (PCC) in micro and macr

Many environmental and health problems are raised from cement manufacturing processes and other factories because those factories emit large amounts of carbon dioxide (CO2) into the atmosphere. Using supplementary cementitious material reduces the am
