The production of ordinary Portland cement releases many greenhouse gases, which have
led to adverse environmental changes such as global warming and climate change. These …

About 120 million tons of red mud is produced worldwide each year. Due to its high basicity
and potential leaching, its storage is a critical environmental problem. This material is …

In response to the requirement for the comprehensive utilization of industrial waste, high-
strength geopolymers were prepared from red mud (RM) and Class 1, 2, and C fly ash (FA) …

A series of geopolymers were prepared by using phosphoric acid as activator to stimulate
high-magnesium nickel slag (HMNS) and fly ash (FA). The effects of amount of phosphoric …

The high liquid content of cast geopolymer not only limits its strength development and
durability but also leads to high energy consumption and carbon dioxide (CO 2) emissions …

Geopolymer offers many advantages over OPC such as excellent mechanical strength,
better durability, thermal resistance, and excellent stability in acidic and alkaline …

The utilization of industrial waste as an aluminosilicate precursor (AP) for alkali-activated
material (AAM) production can provide an outlet for the growing waste stream and relief to …

Today, binders with low CO 2 emissions are preferred in building design. Geopolymers have
lower CO 2 emissions than conventional concrete and Portland cement. This study …

The fly ash geopolymer with improved mechanical properties was prepared by a new
mixture alkali activator. In this paper, sodium tert-butanol, an organic strong alkali was used …

Red mud (RM) and calcium carbide residue (CCR) are waste generated from alumina
refining and acetylene gas producing, respectively. This study utilized alkali-activated …
