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

open access: yesEngineering 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 ...

The Influence of Production Parameters on Pozzolanic Reactivity of Calcined Clays

open access: yesNordic Concrete Research, 2018
Calcined clays are gaining increasing interest as future supplementary cementitious materials for the production of blended cements. Besides the mineralogy, the right production conditions can affect the pozzolanic activity of calcined clays.

In Situ Raman Spectroscopy of a Silica Gel‐Templated Hydration Pathway in CO2‐Activated Cement

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT This study investigates early‐age carbonate mineralization in cementitious systems using in situ Raman microspectroscopy. In the presence of dissolved CO2, clinker phases undergo accelerated dissolution, decomposing to form various calcium carbonate polymorphs and a transient amorphous silica gel network.

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

open access: yesJournal 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 ...
