Optimizing the construction process: State‐of‐art, innovations, and potential benefits of temperature match curing

Structural Concrete, Volume 26, Issue 6, Page 7312-7325, December 2025.
Abstract The temperature match curing (TMC) method significantly enhances the accuracy of concrete property assessments by replicating in situ curing conditions in test specimens. While this method has remained underutilized and relatively unknown in the industry due to its complexity, the advent of Internet of Things and wireless sensor technologies ...

Steel–Mortar and Flexural Mortar–Mortar Bond Strengths of Metakaolin‐Based Geopolymer

Engineering Reports, Volume 7, Issue 11, November 2025.
Metakaolin‐based geopolymer mortar demonstrated significantly higher interfacial bond strength than cement mortar across both mortar–mortar and steel–mortar testing, with performance influenced by interface transition zone (ITZ) roughness and curing age.

Physical, Mechanical, and Volumetric Stability Properties of Mortar With Olive Waste Ash as Cement Substitute

Engineering Reports, Volume 7, Issue 11, November 2025.
Olive waste ash was studied as a cement substitute in mortar. Up to 10% replacement reduced shrinkage and preserved strength, offering a sustainable solution for enhancing volume stability in cementitious systems despite increased water absorption.
