摘要
Presently large amounts of slurry are generated in natural stone processing plants with an important impact on the environment and humans. This paper describes this impact and presents test results showing the feasibility of using this industrial by-product in high-performance concrete production as a substitute of fine aggregates. Test results show that this industrial by-product is capable of improving hardened concrete performance up to 16%, enhancing fresh concrete behaviour and can be used in architectural concrete mixtures containing white cement.
