Compressive resistance of concrete produced with recycled concrete aggregate and sugarcane vinasse waste-water
(2022-02-01)
Vinasse is the main by-product of the sugar and alcohol industry. For each liter of ethanol produced from sugarcane, approximately 12–18 L of vinasse are generated. Being such, its use as a hydration agent in concretes may ...
Understanding the influence of properties of fine recycled aggregates on recycled concrete
(ICE Publishing, 2020-12-07)
Scarcity of fine natural aggregates suitable for concrete, the pollution caused by their mining and the great environmental impact produced by the final disposal of waste concrete, have all motivated several studies about ...
