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

THERMAL RESISTANCE OF ALKALI ACTIVATED SLAG CONCRETE
Proceedings 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

Carbonation process of alkali-activated slag mortars
Journal of Materials Science, 2005 This study analyzes the behaviour of waterglass- or NaOH-activated slag mortars after carbonation. The effect of a superplasticizer based on vinyl copolymer and shrinkage reducing polypropylenglycol derivative admixtures on that process was also examined. The same tests were run on cement mortars for reference purposes. The mortars were carbonated in a

Carbon fibre-reinforced, alkali-activated slag mortars
Materiales de Construcción, 2007 The paper describes the effect of carbon fibre on alkaliactivated slag mortar (AAS) mechanical strength, volume stability and reinforcing steel corrosion, compared to its effect on the same properties in Portland cement (PC) properties. Mechanical strength and volume stability tests were performed as set out in the respective Spanish UNE standards. The

Topics in Cement and Concrete Research [PDF]
, 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 ...
