Construction and demolition waste-based self-healing geopolymer composites for the built environment: An environmental profile assessment and optimization

Namra Mir et al.

Summary: Recycling construction and demolition waste (CDW) to produce green construction materials is essential for decarbonizing the built environment. The study focuses on the life cycle assessment (LCA) of CDW-based self-healing geopolymers, aiming to optimize the environmental implications of the production process and product. The developed geopolymer binder can replace ordinary Portland cement (OPC) in conventional concrete to mitigate its significant global warming impacts.

Self-Healing Glass/Metakaolin-Based Geopolymer Composite Exposed to Molten Sodium Chloride and Potassium Chloride

Patrick F. Keane et al.

Summary: Geopolymers are X-ray amorphous, nanoporous, nanoparticulate materials that can be mixed, poured, and cured under ambient conditions. They are made using a Group 1 alkali activator and an aluminosilicate precursor. Geopolymers are more thermally stable than ordinary Portland cement and have potential applications in thermal energy storage systems.

Effect of curing type on microstructure and compressive strength of geopolymer mortars

Adil Gultekin et al.

Summary: This study investigates the compressive strength and microstructure of different geopolymer mortars. It is found that microwave-cured pumice, perlite, and burnt clay-based mortars have higher strength compared to oven-cured ones, while the strength of fly ash-based mortar decreases upon microwave curing. The energy consumption per unit compressive strength is significantly lower in microwave-cured mortars.

A critical review of engineered geopolymer composite: A low-carbon ultra-high-performance concrete

Nouran Elmesalami et al.

Summary: Bendable concrete is a special type of high-performance concrete with significant environmental impacts due to its high OPC content. Geopolymer is considered a promising alternative to fully replace OPC in ECCs. Research on Engineered Geopolymer Composites (EGCs) is ongoing and further exploration is needed to realize their full potential.

A critical review of engineered geopolymer composite: A low-carbon ultra-high-performance concrete

Nouran Elmesalami et al.

Summary: Bendable concrete (ECC) has a high carbon footprint due to its high content of ordinary Portland cement (OPC), leading researchers to explore geopolymer composites (EGCs) as a low-carbon alternative with promising potential for ultra-high-performance concrete. While EGCs show great promise as low-carbon and ultra-high-performance concretes, further research is needed to fully realize their potential.

Crack self-healing in bio-green concrete

Lei V. Zhang et al.

Summary: The study investigates the potential of using S. pasteurii bacteria for crack self-healing in eco-efficient concrete. Results show that concrete incorporating bacteria can completely heal cracks within 90 days, while control specimens did not show any self-healing. SEM-EDS combined with Raman spectroscopy suggested that calcite was the dominant self-healing product in the concrete.

Sulphuric acid resistance of ground ferronickel slag blended fly ash geopolymer mortar

Jhutan Chandra Kuri et al.

Summary: The geopolymer mortar made by mixing ground ferronickel slag (GFNS) with fly ash exhibits better sulphuric acid resistance than neat fly ash geopolymer mortar, with lower strength loss observed after 12 months of acid exposure. This improvement is attributed to the formation of N-M-A-S-H gel, which creates a more compact microstructure and reduces sulphuric acid ingress. Additionally, the lower deterioration in fly ash-GFNS geopolymer compared to neat fly ash geopolymer is due to the formation of a lower amount of expansive gypsum, as indicated by QXRD analysis.

Effects of fiber hybridization on mechanical properties and autogenous healing of alkali-activated slag-based composites

Jeong-Il Choi et al.

Summary: The study found that AAS composites using hybrid PEPVA fibers had higher tensile strain capacity and superior healing performance compared to composites using only PE fibers at the same total fiber volume fraction. Even at a small volume fraction, the presence of PVA fibers influenced the nature of the healing products.

Amorphous self-healed, chopped basalt fiber-reinforced, geopolymer composites

Patrick F. Keane et al.

Summary: Geopolymer composites containing basalt fibers and low-melting glass were systematically heat-treated at high temperatures, showing improved flexure strength due to the amorphous self-healing effect of the glass frit. The composite transformed into an amorphous self-healed geopolymer (ASH-G) at temperatures up to 900 degrees C and into an amorphous self-healed ceramic (ASH-C) at around 1000 degrees C.
