Development of low energy, thermal and acoustic high performance flowable concrete for use with novel production systems

PROJECT OVERVIEW

This project has arisen from a demand by business to develop a ‘green’ concrete for use in a product and aligns with the key aims of the UK Government policy to reduce CO2 as it brings together a Quinn and QUB team to share knowledge and solve problems to develop a thermal/acoustic high performance flowable concrete with adapted rheology with low carbon foot print for use in some innovative products.

The objects are the optimisation of existing mixes and development of thermal high performance flowable concrete with adapted rheology (SCC) with cost-effectiveness and reduction of consumption of energy and carbon foot print. Therefore a major outcome was the cost savings, increase profit margins, improved working environment and transfer of University research into the company.

Impact of Research

The optimisation of existing mixes and use of waste materials will reduce significantly the cost, improve the competitiveness, reduce carbon foot print and potential to be used for new products such as sea defence, agri-culture precast products, lintels, etc. Additionally, the applied research to pre-cast concrete for modular housing could ultimately influence a major change in the marketplace, which would then have industry wide cost savings.
