Application of low‐emission cement CEM II/C in concrete made with low‐effort processed recycled aggregates

open access: yesStructural Concrete, EarlyView.
Abstract The present study investigates the applicability of recycled concrete aggregates (RCA) for use in structural concrete made with low‐emission cement CEM II/C‐M (global warming potential of 377 kg CO2,eqv.). The aim is to show the potential of RCA processed with minimal energy, water, and economic expenditure.

Performance‐based concept for the selection of sustainable concretes exposed to chlorides

open access: yesStructural Concrete, EarlyView.
Abstract In order to achieve UN Sustainable Development Goals, the construction industry needs to change its current concrete compositions to eco‐friendlier solutions with a much lower carbon footprint. One option is to further increase the use of supplementary cementitious materials as clinker substitution or develop innovative cement and concrete ...

Comparative Evaluation of the Proximate and Cytogenotoxicity of Ash and Rice Chips Used as Mango Fruit Artificial Ripening Agents in Birnin Kebbi, Nigeria [PDF]

open access: yesarXiv
The high demand for mango (Mangifera indica L.) fruits has led sellers to employ ripening agents. However, concerns are growing regarding the potential toxicities of induced ripening, emphasizing the need for scientific investigation. Samples of artificially and naturally ripened mangoes were analyzed for proximate composition using standard protocols.
