Case Study
Devonport and Torpoint Ferry - Devon/Cornwall
Installed in narrow tidal windows (often only one hour) this project, to infill beneath pre-cast slabs, placed significant demands on supply logistics. Project challenges included concerns over chloride ingress in the marine environment, compressive strength of >30N/mm2 at 28 days and installation to an inclined slipway (1 in 8). The supplied solution a microsilica Toproc concrete delivered a combination of high compressive strength, low water/cement ratio and a much reduced rate of chloride diffusion (to conventional gouts).
