Mechanical and Physical Performance of Mortars Incorporating Crushed Hazelnut Shells as Partial Fine Aggregate Replacement

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
This study investigates the mechanical and physical properties of mortars incorporating crushed hazelnut shell (HS) as a partial replacement for fine aggregates. Mortar mixtures were prepared with varying water‐to‐cement (w/c) ratios ranging from 0.35 to 0.50 and HS dosages of 2.5%, 5%, and 7.5% by weight, along with reference mixtures without HS.

Enhanced Utilization of Coal Ash in Construction: Physicochemical Properties and Compressive Strength of Blended Cement and Geopolymer Mortar

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
The properties of fly and bottom ashes produced by Morupule power stations in Botswana are analysed for their pozzolanicity. Furthermore, the influence of physical, chemical and microstructural properties of the ashes on the performance of compressive strength of fly ash–based blended cement and geopolymer mortar was evaluated.

Stone‐Cutting Dust as a Sustainable Supplementary Cementitious Material: A Comprehensive Review of Its Physicochemical and Mechanical Effects

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Ordinary Portland cement (OPC) remains the most common binder used in construction and accounts for nearly 7%‐8% of the world’s CO2 emissions due to calcination of limestone and high energy use during clinker production. Reducing OPC content using SCMs is one of the major strategies to achieve sustainable construction.

Understanding plaster production in Palaepaphos–Hadjiabdoullah, Cyprus, during the Cypro‐Classical period

Archaeometry, Volume 67, Issue 6, Page 1437-1452, December 2025.
Abstract This article discusses the results of analytical work on wall and floor plaster from a secular monument excavated on the plateau of Palaepaphos–Hadjiabdoullah (Cyprus). Excavated within the frame of the Palaepaphos Urban Landscape Project (PULP), funded by the University of Cyprus since 2006, the monument is an extensive multifunction workshop
