Abstract

The drying of refractory and Portland cement concretes has been studied by engineers and scientists for many years and lately research is driven by the need to understand the damage mechanisms to public infrastructure from fires. The development of high performance concrete (HPC), self-compacted concretes (SCC), low cement refractory concrete (LCC), ultra-low cement refractory concrete (ULCC) and no cement refractory concrete (NCC) by selecting the particle size distribution to improve packing and replacing cement with ultrafine particles such as silica fume and hydrateable alumina has enabled compressive strengths to increase to >100 MPa. This means there is an even greater demand on engineers to understand the forced drying of these materials.
