Strength and Drying Shrinkage of Alkali-Activated Slag Paste and Mortar

open access: yesAdvances in Civil Engineering, 2012
The aim of this study is to investigate the strengths and drying shrinkage of alkali-activated slag paste and mortar. Compressive strength, tensile strength, and drying shrinkage of alkali-activated slag paste and mortar were measured with various liquid/

Alkaline cement mortars. Chemical resistance to sulfate and seawater attack [PDF]

open access: yes, 2002
The durability and chemical resistance of alkali activated slag and fly ash/slag mortars in contact with sulfates and seawater media have been studied. Two methods were used in the evaluation of such durability: Kock-Steinegger and ASTM CI012.

Toward Fossil‐Free Steelmaking: Overview of Physiochemical Properties of Hydrochar and Its Application in Blast Furnace and Electric Arc Furnace Processes

open access: yescScience, Volume 1, Issue 1, December 2025.
ABSTRACT The steel industry is among one of the largest CO2 emitters in the world. To meet climate targets, replacing fossil‐based carbon with renewable biocarbon in metallurgical processes, particularly in blast furnaces (BFs) and electric arc furnaces (EAFs), has emerged as a viable short‐ to mid‐term solution.

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

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 ...
