Using Fine Recycled Concrete Aggregate for Mortar Production

Using Fine Recycled Concrete Aggregate for Mortar Production situation occurred in the Silva, Bavaresco6 et al. 4 and Pedrozo8 studies. Most studies consulted found that water retentivity of fresh mortar made with recycled aggregates was lower. Since they

Use of Recycled and Waste Materials in Cement Concrete with

The water absorption of recycled concrete aggregate is higher than natural aggregate which results in an increase in water cement ratio to get required workability of concrete. The resistance of recycled aggregate to mechanical actions i.e., impact and cr

Water absorption limits on aggregates - The Concrete Society

Water absorption limits on aggregates. Limits on aggregate water absorption are rare though they may be useful to link to an undesirable concrete property, such as freeze-thaw susceptibility, as water absorption is easily determined. Historically it is no
