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 ...

(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia CivilUTFPR, 2021-05-19)
The self-compacting concrete is a product developed by Japanese in 1988 and its principal characteristic is the fluidity, with high capacity to occupy the spaces without using vibrator. Is a technology that shows many ...
Recycled Concrete: Mixture Variations to Improve its Durability
(Nova Science Publishers, 2017)
Recycled concrete presents a higher porosity than traditional concrete, making it more susceptible to external agents and favoring the development of different pathologies in reinforced concrete structures. In particular, ...
Corrosion products of reinforcement in concrete in marine and industrial environments
(ELSEVIER SCIENCE SA, 2009)
The corrosion products formed on embedded steel in concrete under simulated marine and industrial conditions and natural marine environment were studied. A 0.50 water/cement ratio concrete was used concrete 3.5% NaCl and ...
