Mix Proportion of Fly Ash Concrete Based on the Strength Contribution Ratio

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
ABSTRACT This study aims to expand the use of fly ash concrete (FAC). Based on an experimental investigation of k values or the contribution of FA addition to the strength of ordinary Portland cement or Portland blast‐furnace slag cement type B, we propose and validate an environmentally friendly mix design for FAC.

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 ...
