Flexural Capacity of Fire-Affected Concrete Members with Recycled Glass Aggregate and Glass Pozzolan

Fire, 2022
Adding recycled glass components to concrete mixes is a novel and sustainable option. Prior studies have recommended replacement ratios of 30% glass aggregates and 20% ground glass pozzolan as optimum substitutions in concrete mixes.

The Role of Awareness in Sustainable Construction Materials Uptake in Developing Economies: Evidence From Nigeria

Sustainable Development, EarlyView.
ABSTRACT Sustainable Construction Materials (SCM) are crucial for reducing lifecycle emissions in the built environment, yet their adoption remains limited in many developing economies, such as Nigeria. This study investigates how awareness influences the adoption of SCM among professionals in Nigeria's Architecture, Engineering, and Construction (AEC)

Significance of fineness of pozzolans in determining pozzolanic reactivity

CEMENT
This paper presents the quantification of the pozzolanic reactivity of pozzolans examined in terms of compressive strength, bound water and electrical resistivity. The pozzolans studied included natural pozzolans, glass pozzolans and fly ash that were ground to four fineness levels or median particle sizes (d50) of approximately 3, 5, 10 and 15 µm ...

Co‐Calcination of Silicate or Aluminosilicate Network of Clay and Non‐Clay Minerals With NaOH: Physicochemical Insights

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
Effects of co‐calcination with alkali hydroxide on pure clay minerals (kaolinite, montmorillonite) and typical impure minerals (quartz, feldspar) are presented. Co‐calcining montmorillonite and quartz with sodium hydroxide improves their reactivity. Co‐calcining kaolinite with sodium hydroxide reduces its reactivity.
