Temporal effects on the micro- and nano-structural cement-slag pastes subjected to microwave curing over 7 years

Case Studies in Construction Materials
This study examines the changes in the micro- and nano-structures of microwave-cured cement and slag pastes over 7 years. The properties of aged samples were compared with those of young pastes made from the same mixtures.

In Situ Thermomechanical Evolution of Geopolymer‐Bonded Castables Containing Alternative Aluminosilicate Precursors

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
ABSTRACT Geopolymer binders have emerged as promising alternatives to calcium aluminate cement (CAC) for refractory castables, although their thermomechanical behavior during heating remains poorly understood. This work investigates high‐alumina refractory castables bonded with geopolymers produced from metakaolin (MK), calcined kaolin (CC), and an ...

Modifying admixtures to cement compositions produced from local raw materials

MATEC Web of Conferences, 2018
Durability of hardened cement paste depends on chemical and mineralogical composition of Portland cement. The main factor for hardened cement paste is higher content of calcium aluminate and free calcium hydroxide, binding of which into water-insoluble ...

Degradation of Silicate Glass Used as Fine Aggregate in Concrete

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
ABSTRACT A large body of literature has previously reported on the deleterious expansion which occurs if recycled soda lime silica (SLS) bottle glass is used as fine aggregate in concrete cast with ordinary Portland cement (OPC). It is theorized that this expansion is due to a propensity for the formation of a volume‐expanding alkali–silica reaction ...

Elephant‐Skin‐Inspired Porous Cementitious Tiles with Programmable Crack Networks for Passive Cooling

Advanced Materials, Volume 38, Issue 44, 7 August 2026.
Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Assessment of durability of calcium aluminate cement concrete with the addition of slag

, 2022
Iako je cement najkorišteniji materijal u građevinskoj industriji njegova uporaba znatno utječe na okoliš u negativnom smislu zbog oslobađanja velikih količina ugljikovog dioksida prilikom njegove proizvodnje.

Injectable Bone Cements: A Generational Framework for Bioactivity, Porosity, and Mechanobiological Design at the Nanoscale

Advanced NanoBiomed Research, Volume 6, Issue 8, August 2026.
Key demographic, biological, and material considerations that drive the need for advanced injectable bone cement technologies. Injectable bone cements (IBCs) are widely used in orthopaedic and craniofacial applications due to their minimally invasive delivery and ability to provide early mechanical stabilisation.

Potential of Saudi Arabian bauxite to produce low-carbon cement

Cement
To produce calcium aluminate cement (CAC), bauxites are usually fused with lime/limestone at high temperature (1600 °C). At this temperature, the bauxite´s hydrates of alumina break down - dehydroxylation - and combine with calcium forming monocalcium ...
