External sulfate attack on alkali-activated fly ash-blast furnace slag composite
(Elsevier Sci Ltd, Oxford, 2017)
Reliable durability testing of alkali-activated binders, which might serve as a basis for the prediction of long-term field performance, is one of the main challenges towards broader commercial applications of AAB. This ...
External sulfate attack on alkali-activated slag
(Elsevier Sci Ltd, Oxford, 2013)
This paper analyses the effects of external sulfate attack (5% Na2SO4 solution) on mechanical and microstructural properties of alkali-activated slag (AAS). Portland-slag cement (CEM II/A-S 42.5N) was used as a benchmark ...
Effects of the concentrated NH4NO3 solution on mechanical properties and structure of the fly ash based geopolymers
(Elsevier Sci Ltd, Oxford, 2013)
The geopolymers based on fly ash were exposed to the concentrated (6 M) NH4NO3 solution for 540 days. The highest compressive strength decrease occurred in the initial 28 days testing period. Study of the effects of the ...
