Microstructure and Performance Optimization of Barley Husk Ash–Blended Mortars: A Sustainable Approach to Cement Substitution

Engineering Reports, Volume 8, Issue 4, April 2026.
Barley husk ash (BHA), an agricultural byproduct rich in pozzolanic oxides, was optimized as a sustainable cement substitute. Statistical modeling and experimental validation confirmed 22.75% BHA as the optimal replacement, enhancing mechanical and durability performance while advancing eco‐efficient construction practices.

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.

Evaluating and comparing the effect of zeolite, micro-silica, and fly ash on the mechanical properties of recycled concrete made of 100% recycled aggregates [PDF]

Journal of Structural and Construction Engineering, 2019
Today, restrictions on access to natural aggregate resources in concrete production have become one of the problems in many countries. Concrete, as one of the most widely used human products, is a factor in consuming a large amount of aggregate.

Natural Pozzolan as a Partial Substitute for Cement in Concrete [PDF]

The Open Construction and Building Technology Journal, 2013
In this paper, the use of natural pozzolan as a partial cement substitute in concrete materials is investigated. By means of a test series, four mixes using three types of natural pozzolan, as well as a Class F fly ash, are evaluated. The effectiveness of each pozzolan in controlling alkali-silica reactions has been studied.
