Comprehensive study on the most sustainable concrete design made of recycled concrete, glass and mineral wool from C&D wastes

This study focuses on formulating the most sustainable concrete by incorporating recycled concrete aggregates and other products retrieved from construction and demolition (C&D) activities. Both recycled coarse aggregates (RCA) and recycled fine aggregates (RFA) are firstly used to fully replace the natural coarse and fine aggregates in...

Treatment of end-of-life concrete in an innovative heating-air classification system for circular cement-based products

A stronger commitment towards Green Building and circular economy, in response to environmental concerns and economic trends, is evident in modern industrial cement and concrete production processes. The critical demand for an overall reduction in the environmental impact of the construction sector can be met through the consumption of high...

Concrete mixing monitoring by image analysis applied to recycled aggregate concrete

The improvement of inline mixer measurements is imposed in a growing concrete industry employing increasingly complex manufacturing processes and materials. Improper mixing, water content estimation and fresh properties control are one of the most important concerns of concrete manufacturers. These problems have increased in recent decades due...
