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.

Strength and hydration properties of reactive MgO-activated ground granulated blastfurnace slag paste [PDF]

open access: yes, 2014
Ground granulated blastfurnace slag (GGBS) is widely used as a partial replacement for Portland cement or as the major component in the alkali-activated cement to give a clinker-free binder.

Influence of Calcium Sulfate Type on Evolution of Reaction Products and Strength in NaOH- and CaO-Activated Ground Granulated Blast-Furnace Slag [PDF]

open access: yes, 2018
This study investigated the influences of CaSO4 type (i.e., anhydrite vs. gypsum) on strength development and reaction products in the activation of ground granulated blast-furnace slag (GGBFS) when different activators (i.e., CaO vs.

Design of inorganic polymer mortar from ferricalsialic and calsialic slags for indoor humidity control [PDF]

open access: yes, 2016
Amorphous silica and alumina of metakaolin are used to adjust the bulk composition of black (BSS) and white (WSS) steel slag to prepare alkali-activated (AAS) mortars consolidated at room temperature.

THERMAL RESISTANCE OF ALKALI ACTIVATED SLAG CONCRETE

open access: yesProceedings of International Structural Engineering and Construction, 2017
This study investigated the thermal resistance of Alkali Activated Slag (AAS) concrete. Alkali Activated Slag cement is an environmentally friendly alternative to Portland cement, which can be produced by using an alkaline solution to activate the binding effect of the blast furnace slag. Heat from fire changes the physical and mechanical properties of

Performance, thermodynamic modelling, and global warming potential of low sodium-activated artificial granulated slag substituted with quartz and limestone fillers

open access: yesCleaner Engineering and Technology
Commercialization of alkali-activated slag faces, among others, two major hurdles: limited availability of blast-furnace slag and the high cost of alkaline activators.

Topics in Cement and Concrete Research [PDF]

open access: yes, 2006
In recent decades, the construction sector has faced many changes. One of these changes is the shift in the role of national government from one-sided practices in which the government was solely responsible for strategic and long-term spatial planning ...
