Replace Conventional Aggregates in Concrete

Recycled aggregate concrete (RAC), produced with partial or total replacement of natural aggregates by recycled aggregates in the concrete mix, has been shown to provide significant environmental benefits and economic benefits, such as the decrease of the consumption of natural resources and of the volume of waste sent to dumping grounds [8,9].

Aggregates such as: Rock; Sand; Gravel; Water is the lightest of all these ingredients. And not all of it gets absorbed by the sand and cement. For these reasons, this will cause excess water to rise to the surface. The water will then pool on the surface of the concrete. This is known as bleed water. Fiber mesh concrete bleeds more evenly than ...
