Workability and mechanical properties of alkali-activated fly ash-slag concrete cured at ambient temperature [PDF]

open access: yes, 2018
Alkali-activated fly ash-slag (AAFS) concrete is a new blended alkali-activated concrete that has been increasingly studied over the past decades because of its environmental benefits and superior engineering properties. However, there is still a lack of

Mechanical Performance Optimization and Microstructural Mechanism Study of Alkali-Activated Steel Slag–Slag Cementitious Materials

open access: yesBuildings
The optimal proportion of alkali-activated steel slag–slag cementitious materials is investigated by considering the combined effects of steel slag content, alkali content, water glass modulus, and water–binder ratio using the Box–Behnken design in ...

Components of the Fracture Response of Alkali-Activated Slag Composites with Steel Microfibers

open access: yesApplied Sciences, 2019
Knowledge of the mechanical and primarily fracture parameters of composites with a brittle matrix is essential for the quantification of their resistance to crack initiation and growth, and also for the specification of material model parameters employed

Environmentally Friendly Pervious Concrete for Treating Deicer-Laden Stormwater: Phase I [PDF]

open access: yes, 2015
A graphene oxide-modified pervious concrete was developed by using low-reactivity, high-calcium fly ash as sole binder and chemical activators and other admixtures.

Strength and drying shrinkage of slag paste activated by sodium carbonate and reactive MgO [PDF]

open access: yes, 2015
This paper investigates the potential of combining Na2CO3 and reactive MgO as a sustainable activator for ground granulated blastfurnace slag. Two very different reactivity MgOs were added at 5–10 % and the Na2CO3 content varied from 4% to 8% by the ...

An effective approach to improve the performance of PC-based superplasticizer in alkali-activated slag [PDF]

open access: yes, 2016
The lack of workability has hindered the industriallisation of alkali-activated slag (AAS) - a novel, low carbon cementitious building material. In order to address this main barrier, adding superplasticiser (SP) is essential.

Extensive reuse of soda-lime waste glass in fly ash-based geopolymers [PDF]

open access: yes, 2018
The possibility of extensive incorporation of soda-lime waste glass in the synthesis of fly ash-based geopolymers was investigated. Using waste glass as silica supplier avoids the use of water glass solution as chemical activator.

Investigating the impact of foundry by-product sand as an activator on workability improvement and strength development in alkali-activated blast furnace slag mortar

open access: yesResults in Materials
The substitution of alkali-activated furnace slag significantly reduces the necessity of cement manufacture and mitigates the continuous growth of carbon emissions.
