Development of Sustainable Paver Block to Suit Very Heavy Traffic Conditions Using Cassava Peel Ash

Engineering Reports, Volume 8, Issue 5, May 2026.
Sustainable paver blocks were developed using cassava peel ash and silane‐treated glass fibers. The optimized mix achieved superior strength, durability, and impact resistance, meeting IS 15658:2006 standards for heavy traffic. This eco‐friendly approach highlights an effective use of agro‐waste and fiber reinforcement for sustainable infrastructure ...

Chemical and Microstructural Evolution of Cement Pastes with Additives and SCMs During the First 24 h

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT Early‐age chemical evolution governs the development of hydrate assemblages and microstructure in cementitious systems, especially when additives and supplementary cementitious materials are incorporated. This study investigates the first 24 h of hydration in Portland cement pastes modified with selected additives and supplementary ...

A Termite‐Inspired Alternative to Cement

Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,

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)

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.
