Sustainable and Seismically Resilient Confined Masonry: Global Progress in Research and Design Practice

Earthquake Spectra, Volume 42, Issue 4, November 2026.
Modern confined masonry (CM) construction consists of masonry walls confined by reinforced concrete (RC) tie‐columns and tie‐beams. When built correctly, CM buildings have shown good performance in earthquake's shaking. Even though CM construction has been practised for almost a century in some Latin American countries, its use and standardisation are ...

Microbial Deterioration Potential and Mitigation Strategies in Blended Cement Structures: A Review

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Microbial‐induced deterioration (MID) is a threat to the durability of cement‐based materials (CBMs) particularly in sewer and wastewater systems. Whereas blended cements incorporating supplementary cementitious materials (SCMs) offer environmental benefits such as reduced carbon (IV) oxide (CO2) emissions and enhanced mechanical performance, their ...

Enhancing Expansive Soil Stability Using Agricultural Waste: Soybean Pod Ash and Banana Fiber

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study evaluates the efficacy of agricultural waste—soybean pod ash (SBPA) and banana fiber (BF)—as sustainable stabilizers for expansive soils in Jimma Town, Ethiopia. Soil samples from Kebele 5 and Ajip Kela (1.50 m depth) with the highest plasticity indices and lowest California bearing ratio (CBR) values were selected.

Investigation on the Potential of Bacteria‐Coated Jute Fiber for Enhancing Mechanical Properties and Self‐Healing Capabilities in Concrete

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Concrete faces challenges such as low tensile strength, susceptibility to cracking, and limited self‐healing capabilities. To address these issues, natural fibers have gained attention as reinforcements due to their high specific strength, stiffness, biodegradability, and renewability.
