Use of selected waste materials in concrete mixes

The waste materials considered to be recycled in this study consist of glass, plastics, and demolished concrete. Such recycling not only helps conserve natural resources, but also helps solve a growing waste disposal crisis. Ground plastics and glass were used to replace up to 20% of fine aggregates in concrete mixes, while crushed concrete was used to replace up to 20% of coarse aggregates. To

The Use of Recycled Material in Concrete - UKDiss

10/12/2019  The usage of recycled materials in concrete is a new construction method which is beginning to take effect across Europe. Through both literary and practical research, the main aspects regarding this method will be looked at in detail to determine if using recycled materials in a concrete design is a suitable green and environmentally friendly way of addressing the issue of rubble. Also to be determined is whether or not a significant cost benefit can be achieved by recycling building waste ...
