Abstract

Geogrid Mechanical Damage Caused by Recycled Construction and Demolition Waste (RCDW): Influence of Grain Size Distribution

Highlights

  • Due to its need of using a tremendous variety of materials and processes, the construction industry plays a significant role in environmental issues, not just as a domestic industry, but on a global scale

  • These results show the need for a better separation of the materials that compose the recycled construction and demolition waste (RCDW), once the existence of components that could be broken can cause different damages in the geogrid tested

  • This paper reported on mechanical damage caused to geogrids by recycled construction and demolition wastes (RCDW) with different grain size distributions

Summary

Introduction

Due to its need of using a tremendous variety of materials and processes, the construction industry plays a significant role in environmental issues, not just as a domestic industry, but on a global scale. Preventing environmental, economic, and social impacts caused by the construction and demolition wastes (CDW) demands attitude changes in order to turn the efficient management and reuse of these wastes into worldwide goals. In this context, geosynthetics appear as modern and environmentally friendly products derived from researches and development of the polymer industry and geotechnical engineering. Geosynthetics appear as modern and environmentally friendly products derived from researches and development of the polymer industry and geotechnical engineering These materials have been increasingly used in geotechnical engineering due to their economic and environmental benefits. Geosynthetic reinforced soil (GRS) walls have presented a series of positive ecological parameters when compared to traditional concrete cantilever walls (Jones, 1994), which include 40 % less SO2 released into the atmosphere during the fabrication of their component parts
