Abstract:
A large-scale experimental investigation to measure the form pressures exerted by self-consolidating concrete (SCC) was performed in Toronto, ON, Canada. The experimental program is described and measured lateral pressures are compared with values calculated using various predictive approaches available in the published literature. A key recommendation: Unless the stiffening characteristics of the SCC mixture are prequalified and verified by field measurements, formwork should be designed to resist full hydrostatic pressure.
