Corrosion resistance of alkali-activated slag cement
Advances in Cement Research, 2003This paper examines the corrosion of alkali-activated blast furnace slag cement in pH 3 nitric acid, pH 3 acetic acid, 30% CaCl2 solution and 15% CO2 atmosphere at relative humidity of 52%. ASTM Type I Portland cement is used as a reference. Experimental results indicate that alkali-activated slag pastes are corroded more slowly than Portland cement ...

Perlite Concrete Based on Alkali Activated Cements
Advanced Materials Research, 2014The use of the alkali activated cements for the manufacture of perlite concrete pressed and vibro-pressed products for heat insulation intended for various purposes was studied. The interfacial transition zone perlite grain cement stone was examined in order to reveal features of its formation.

Hydrated Portland cement as an admixture to alkali-activated slag cement
Advances in Cement Research, 2015Waste concrete powder is a promising mineral admixture to Portland cements and alternative binders such as alkali-activated slag cements (AASC). The individual constituent of the waste concrete powder is mechanically activated in the ground hardened cement paste (GHCP).

Alkali activated natural pozzolans for geopolymer cement
2021This thesis deals with the use of six natural pozzolans from Germany and Italy for geopolymer production. As the first part, a detailed study was conducted on the effect of silica modulus of sodium silicate solution and mineralogical composition of natural pozzolans on the extend of geopolymer reaction, reaction kinetics, mechanical properties, and ...

Alkali-activated clay-based cement and mortar
Considerable research has been undertaken on metakaolin and alkali-activated waste binders for geopolymer concrete production. However, very little work has focussed on developing clay-based geopolymer concretes. Clay based geopolymer indicates that new clay based binder possess significant potential to be an alternative material to ordinary Portland ...openaire +1 more source
