Abstract
Describes the criteria governing the striking of formwork. Methods for predicting striking times using computer programs are reviewed and the applications of these systems are described. Guidance is also given on techniques for reducing striking times where these are considered excessive. The methods for determining the formwork striking times are described together with their advantages and weaknesses. Appendices give a method for calculating the concrete strength required for a structure to withstand wind loading shortly after removal of formwork and an example of the calculation of maturity using the Sadgrove formula.
