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

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

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 ...

Industrial calcination of kaolinitic clays to make reactive pozzolans
This paper presents the results of an industrial trial for the production of calcined clay to be used as pozzolan in cement manufacture. For the trial, a wet-process clinker rotary kiln was modified to process on dry basis the low grade kaolinitic clay used as raw material.

Scalable Electrochemical Concrete Fabrication and Closed‐Loop Recycling
The electrochemical‐driven recycling strategy establishes a reversible concrete material flow by extracting Ca, Si, Al, and Fe from concrete waste and regenerating functional feedstocks. These reversed products are reassembled into new concrete, which re‐enters service and ultimately returns to waste, enabling a closed‐loop, waste‐origin, and low ...
