The degradation of material induced by sulfate attack is major durability problem facing
cementitious materials. In this paper, to illustrate the nanoscale chemical degradation …

This paper presented the role of supplementary cementitious materials (SCMs), including fly
ash (FA), granulated blast-furnace slag (GBFS), and silica fume (SF) in long-term resistance …

In this work, the effects of slag/fly ash ratios, Na 2 O concentration, and silicate modulus (Ms)
of activators on the reaction mechanism of sulfate attack on alkali-activated slag/fly ash …

Calcium leaching from cement hydrates to pore solution increases the porosity and reduces
the bonding strength of cement hydrates, accelerating the degradation of concrete. Calcium …

Although the high efficiency of coupled lithium and saturated metakaolin in alkali-silica
reaction mitigation has been documented, its influence on cement hydration remains …

This paper investigates the quantification of ettringite (Ca 6 Al 2 (SO 4) 3 (OH) 12. 26H 2 O,
AFt), gypsum (CaSO 4. 2H 2 O, Gy) and Friedel's salt (Ca 4 Al 2 (OH) 12 Cl 2. 4H 2 O, Fs) …

The work in hand presents the results of an experimental research on the effect of different
precursors (binders) used in alkali-activated materials (AMM) and its composition (ie SiO …

The safety of partially exposed concrete structures is threatened by the complicated
corrosive sources in sulfate-rich saline areas. Experimental tests were conducted in the …

This study aims to investigate the durability and microstructure of cement-sodium silicate
grouts with high water to binder ratios (w/b) of 1.1–2.5 upon exposure to sea water. Grout …

The well-known weakness of cement concrete against external/internal sulphate attack and
an estimated 7-10% global greenhouse gas emission by the construction industry (mainly …
