Fracture properties of alkali activated mortars

Proceedings of the 10th International Conference on Fracture Mechanics of Concrete and Concrete Structures, 2019
In this paper, three different coal fly ash-based alkali activated mortars are studied. The three different mortars are obtained using the same binding system but different types (i.e. silica sand or expanded perlite) and sizes of aggregates. Small-scale beams are constructed together with additional specimens for material characterization.

Decalcification resistance of alkali-activated slag

Journal of Hazardous Materials, 2012
This paper analyses the effects of decalcification in concentrated 6M NH(4)NO(3) solution on mechanical and microstructural properties of alkali-activated slag (AAS). Portland-slag cement (CEM II/A-S 42.5 N) was used as a benchmark material. Decalcification process led to a decrease in strength, both in AAS and in CEM II, and this effect was more ...

Properties of alkali-activated clinoptilolite

Cement and Concrete Research, 2000
Abstract Materials made by hydrating the natural zeolite clinoptilolite with calcium hydroxide (Ca(OH)2) have been characterised and compared to other alkali-activated waste-derived and naturally occurring pozzolana. Compressive strength is dependent on the Ca(OH)2 content, clinoptilolite particle size, and curing conditions. Optimising each of these

Alkali activation of basalt

2014
To further reduce the emission of greenhouse gasses, raw materials that can be directly alkali activated are looked for. In this study the reaction of basalt with concentrated NaOH or KOH solutions to form geopolymer like materials is investigated. A comparison with alkali activated kaolinite is made.
