In the last three decades, the gigantic demand for sustainable and environmentally friendly
concrete with reduced environmental footprints has resulted in the development of low …

This review provides a comprehensive study of the fundamentals of the alkaline and acid
activation of volcanic ashes (VA), for mainstreaming their use as a conventional feedstock …

Reaction mechanism of phosphoric activated metakaolin is studied by techniques of
calorimetry, ICP-OES, FTIR and NMR taking curing temperature and [H 3 PO 4] as variables …

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 …

Phosphogypsum (PG) constitutes the principal by-product of the phosphate industry which
largely restricts its wide development. The incorporation of PG as a reinforcement agent into …

This research investigates the fire resistance of novel geopolymer (GP) foams, based on
alkali-activated metakaolin and silica fume (SF). Fresh GP foams are applied as coatings on …

Coal ash-based geopolymers with mine tailings addition activated with phosphate acid were
synthesized for the first time at room temperature. In addition, three types of aluminosilicate …

The porous nature of coral aggregate challenges the manufacturing of high performance
coral concrete, which obstacles its development and application. By using microbubble …

The aim of this study was to investigate the process conditions, hydration reaction products
and mechanism of high-magnesium nickel slag (HMNS)-fly ash (FA) as a precursor of …

Aluminosilicate phosphate (ASP) geopolymers are a new kind of green cementitious
materials synthesized from aluminosilicate precursors and acidic activators (phosphoric acid …
