Recycled Aggregate in Concrete Production: A New
2017-12-19 · Carbon-conditioning reduces porosity and water absorbency of recycled aggregate. In addition to improve recycled aggregate quality, CO 2 emissions from the aggregate also help filling openings in the concrete composition, generating an improved bond matrix. These two traits assist in enhancing the recycled concrete properties.
