Geosynthetic Cementitious Composite Mat in Mining Channel Lining Applications

GCCM used in Channel Lining
Construction of channel drainage system on projects has become a major challenge both in terms of time and cost. Not only do asset companies need to manage their facilities in accordance with budget, they also need to ensure that the interference of construction, maintenance and upgrades has a minimal effect on the operating capacity of these facilities. The use of traditional concrete solutions in channel lining applications on projects has become a major challenge both in terms of time and cost and alternative solutions are often required. Geosynthetic Cementitious Composite Mats (GCCMs) are deployed in roll format (like conventional geosynthetics), but on hydration they harden to form a thin, fibre reinforced concrete layer. GCCMs allow for overall project cost savings, replacing traditional concrete techniques through ease of maintenance and rapid installation.
This paper reviews how a GCCM has been used to replace a poured concrete solution on a newly constructed channel at a mine site in the state of Minas Gerais, Brazil. The aim of the project was to create a channel which would direct tailing from mine and rain water through a tailing pond which was under reconstruction. The case study provides insight into the physical properties and practical benefits of GCCM utilisation within the core Civil and Mining sectors.
