Purpose and goal
This project is to apply functionalized graphene (FG) into concrete to maintain the performance while reducing the weight, contributing to a new generation of better fence materials in Sweden. The goal is to reduce the amount of concrete by adding FG while keeping the strength, especially the flexural strength for fence applications. The quality of functionalized graphene with an up-scaling level will be well-controlled, and the dispersion of FG in concrete for on-site testing will be improved.
Expected results and effects
By reducing the amount of concrete and the intrinsic curing time, the addition of FG is expected to enable stronger more durable fence post foundations with less material usage during a longer part of the season regardless of geographical location. The environmental implications are direct in terms of less material that requires transportation to sites. This reduces emissions from transport and people’s labor. Swedish building sector will also benefit from improved graphene based light weight structures for future Swedish sustainable building and constructions.
Planned approach and implementation
The project starts in May 2018. SHT will supply FG to HEDA, with knowledge of mixing nanomaterial into the cement composite. Chalmers will focus on the material evaluation, and HEDA will install the concrete fence on test sites and monitor the development of the fence with sensors. In the first 3-6 months, the intensive test of graphene cement composite in the lab will be carried out. Fast aging test of the fence application will also be carried out. In parallel on-site tests will be set up to experience winter, frost condition and wind impact.
