Recycled Concrete Buildings - Fibo Intercon Batching plant

Due to the greater focus on minimising CO 2 emissions in the construction industry, Pelican Self Storage wanted to demonstrate the production of concrete structures that have aggregates made from crushed concrete and bricks from demolished buildings.. The purpose of the project was therefore to develop a total concept for the on-site reuse of the demolition materials.

QA: Basics of recycled concrete - Metso Outotec

Nov 19, 2021  Recycled aggregate is waste material from demolished buildings or bridges, for example. When demolishing such structures, the waste needs to be sorted into wood, glass, etc. and concrete. This is called selective demolition, as the structure isn’t knocked down as a whole, but the materials are taken down selectively.

May 20, 2014  Recycled coarse aggregate (RCA) made from waste concrete is not a suitable structural material as it has high absorption of cement mortar, which adheres on the aggregate surface and on the tiny cracks thereon. Therefore, when using RCA made from waste concrete, much water must be added with the concrete, and slump loss occurs when transporting.
