  • Concrete Produced Using Crushed Bricks As Aggregate

    Feb 10 2021 This paper presents the fresh and hardened properties of high strength concrete comprising byproduct fine crushed aggregates (FCAs) sourced from the crushing of three different types of rocks namely granophyre basalt and granite The lowest void contents of the combined fine aggregates were observed when 40 to 60 of natural sand is replaced by the FCAs.Sep 18 2019 Use of recycled concrete aggregates containing sludge also deteriorated the consistency and increased the air content but at the same time slightly reduced the density of the concrete mix The use of sludge as a substitute for sand or recycled concrete aggregate as a replacement of natural aggregate affected the absorption of concrete.
