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 ...

Valorization of Crushed Fly Ash Brick Waste as a Low‐Carbon Binder for Sustainable Concrete Production

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
The construction industry significantly contributes to global CO2 emissions, with cement production being a major factor. Concurrently, large quantities of crushed fly ash brick (CFAB) waste accumulate due to manufacturing defects. In this study, CFAB powder was developed as a supplementary cementitious material (SCM) by partially replacing cement in ...

Effects of Partial Substitution of Ordinary Portland Cement With Stone‐Cutting Dust, Limestone, and Natural Pozzolana on Compressive Strength and Microstructure

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Rapid industrialization and urban growth have driven a rising demand for cement, yet ordinary Portland cement (OPC) production remains energy‐intensive and a major source of CO2 emissions. The partial substitution of OPC with supplementary cementitious materials (SCMs) offers a sustainable route to reduce environmental impact, production costs, and ...

Modification of the Performance of Fresh and Hardened Concrete Reinforced With Fibers From Oil Palm Mesocarp

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Currently, many researchers use industrial or agricultural by‐products (waste) as raw materials for the construction sector. These wastes are economical and help preserve the environment through good waste management. For this purpose, oil palm mesocarp fibers (OPMFs) are used at various volume concentrations (0%, 0.25%, 0.5%, and 1%) for the ...

Performance of Concrete Using Water Hyacinth Ash as a Partial Cement Substitute

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Concrete is one of the most widely used construction materials, with cement as its primary component. However, cement production significantly contributes to CO2 emissions, posing environmental challenges. This study investigates the use of water hyacinth ash (WHA) as a sustainable partial replacement for cement in C‐30 grade concrete.
