An Exploratory Study on Alkali-Activated Slag Blended with Microsize Metakaolin Particles Under the Effect of Seawater Attack and Tidal Zone

Alaa M. Rashad et al.

Summary: The study investigated the impact of different marine environments on the compressive strength and microstructure properties of building materials, with wet/dry curing conditions causing more severe damage to specimens. The neat AAS pastes showed better strength and microstructure than those blended with mK.

Improving the carbonation resistance of Na2CO3-activated slag mixes via the use of reactive MgO and nucleation seeding

N. T. Dung et al.

Summary: This study explored the enhanced carbonation resistance of Na2CO3-activated slag (SCAS) concrete through the addition of hydromagnesite seeds (S) and reactive MgO (M). The presence of these additives led to the conversion of MgO into hydrated magnesium carbonates (HMCs) and the formation of hydrotalcite, which contributed to denser microstructures and improved compressive strength. Overall, the inclusion of S and M enabled the retention of hydration products, formation of additional carbonation products, and a significant increase in compressive strength after carbonation.

The role of recycled waste glass incorporation on the carbonation behaviour of sodium carbonate activated slag mortar

G. Liu et al.

Summary: This study found that using a high dosage of sodium carbonate or water glass as an activator can enhance the resistance to carbonation of sodium carbonate activated GGBS mortars, and adding 30% RGP to the GGBS binder system can significantly improve resistance to carbonation while reducing carbonation shrinkage and improving strength performance.

Properties and corrosion behaviour of applicable binary and ternary geopolymer blends

Mahmoud Gharieb et al.

Summary: The study found that ternary blends of 50% slag, 40% metakaolin, and 10% fly ash exhibited the highest compressive strength, lowest porosity, and lowest corrosion rate, while blends of 60% slag, 30% metakaolin, and 10% fly ash ranked second. The laboratory techniques of differential thermal analysis and Fourier-transform infrared spectroscopy were used to analyze the thermal properties and molecular structure of the samples.
