RECYCLED POROUS CONCRETE EFFECTIVENESS FOR FILTRATION MATERIAL ON WASTEWATER TREATMENT

Effects of Recycled Concrete Aggregates on Properties of Asphalt Concrete

Adsorption and Biological Filtration in Wastewater Treatment

Recycled PET Nanofibers for Water Filtration Applications

Water shortage is an immediate and serious threat to our world population. Inexpensive and scalable methods to clean freshwater and wastewater are in high demand. Nanofiber filtration membranes represent a next generation nonwoven filter media due to their unique properties. Polyethlyene terephthalate (PET) is often used in the packaging of water and other commonly used materials, leading to a ...

A PARTICLE SWARM OPTIMIZATION ALGORITHM TO SUGGEST FORMULAS FOR THE BEHAVIOUR OF THE RECYCLED MATERIAL REINFORCED CONCRETE BEAMS

Reducing waste material plays an essential role for engineers in the current world. Nowadays, recycled materials are going to be used in order to manufacture concrete beams. Previous studies concluded that the currently proposed formulas to predict the flexural and shear behavior of the reinforced concrete beams were not appropriate for those manufactured by recycled materials. This study aims ...

Reactivity in Recycled Concrete Aggregate

Full scale tests with crushed concrete used in sub-bases in roads show that the material has capacity to reharden, very slowly but also after prolonged periods of time. The rehardening process in crushed concrete aggregate has been analysed with a thermogravimetric method, comparing the change in chemical composition in the aggregate when set with water, compacted and hardened. It has been show...
