Inverse Vulcanized Sulfur Polymer Composites From Poultry‐Industry Products and Lignocellulosic Biomass Waste

Journal of Applied Polymer Science, EarlyView.
This work explores the use of various fillers, including eggshell powder, feather meal, peanut hulls, and sawdust to reinforce a base binder GFS90 (comprised of 90 wt.% sulfur, 5 wt.% chicken fat, and 5 wt.% sunflower oil). The resulting composites showed impressive compressive strengths ranging from 15.3 to 36.2 MPa, making them a potential ...

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 ...

Effect of acidic volcanic perlite rock on physio-mechanical properties and microstructure of natural pozzolan based geopolymers

Case Studies in Construction Materials, 2021
The paper presents the combined effect of pozzolan, as an alkaline volcanic rock, and perlite, as an acidic volcanic rock, in the synthesis of geopolymers. The perlite proportion varied between 0% and 50% by weight. A mixture of sodium silicate (Na2SiO3)

Synergistic Effects of Silica and Calcium‐Based Dual Admixtures on the Flowability, Microstructure, and Strength Development in Low‐Carbon Concrete

Applied Research, Volume 5, Issue 4, August 2026.
ABSTRACT Eco‐friendly construction practices have emerged as a cornerstone of modern development. Due to the substantial carbon emissions from cement production, there is a growing demand for supplementary cementitious materials. This study investigated the synergistic effects of two different wastes, silica‐rich rice husk ash (RHA) and calcium‐rich ...
