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 ...

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.
