TLDR
In this paper, the effect of physical sulfate attack on pozzolanic additions, the resistance of plain and blended cement mortars was investigated using 10% Na 2 SO 4 and MgSO 4 solutions under four exposure regimes which included the standard conventional exposure and field-like exposures that created the physical sulphate attack.About:

Durability of mortar using waste glass powder as cement replacement
TL;DR: In this article, waste glass was ground and used in mortar as a partial cement replacement (0, 10% and 20%) material to ascertain applicability in concrete, and an extensive experimental program was carried out including pozzolanic activity, setting time, soundness, specific gravity, chemical analyses, laser particle size distribution, X-ray diffraction and scanning electron microscopy (SEM) on WGP and resistance to alkali silica reaction (ASR), chloride ion penetration resistance, absorption by capillarity, accelerated carbonation and external sulphate resistance on mortar

Idawati Ismail,Idawati Ismail,Susan A. Bernal,John L. Provis,John L. Provis,Sinin Hamdan,Jannie S.J. van Deventer +6 more
TL;DR: In this paper, the performance of fly ash/slag geopolymer binders was investigated in different forms of sulfate exposure, specifically, immersion in 5 ¾wt% magnesium sulfate or 5 ¼wt% sodium sulfate solutions, for 3 months.

Durability of alkali-activated materials in aggressive environments: A review on recent studies
TL;DR: In this paper, the authors reviewed factors influencing water absorption and permeability of AAMs, effect of gel composition and exposure environments on carbonation, chloride penetration, and chloride migration test methods, and sulfate resistance in high-calcium and lowcalcium alkali-activated systems.

Study on the expansion of concrete under attack of sulfate and sulfate–chloride ions
TL;DR: In this paper, a theoretical expansion model is proposed for predicting the stresses, strains and volume expansion developed during the process of sulfate attack, based on the assumption that concrete may be treated as a porous visco-elastic material, and was developed by using a micromechanics approach method.
Journal ArticleDOI
Investigation of concrete exposed to dual sulfate attack
TL;DR: In this article, the surface scaling of concrete partially immersed in sulfate solutions and exposed to cyclic temperature and relative humidity was explored, showing that the lower immersed portion can suffer from chemical sulfate attack, while the upper portion is vulnerable to physical attack.

Salt damage in porous materials: how high supersaturations are generated
TL;DR: In this article, the thermodynamics of real solutions for sodium sulfate and sodium chloride have been investigated and it was shown that dissolution of its anhydrate produces supersaturations with respect to its decahydrate capable of generating tensile hoop stresses on the order of 10-20 MPa, largely in excess of the tensile strength of almost all stones.
