Abstract:
Self-consolidating concrete (SCC) mixtures were tested and wall and column elements were instrumented to determine formwork pressures during placement. The findings confirm that test methods for evaluating the structural build-up of SCC can be used in conjunction with recently developed prediction models to determine the maximum formwork pressure exerted by SCC. An additional model allows prediction of the rate of pressure drop with time.
