Publisher's Synopsis
This report 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 excessive striking times. The methods for determining formwork striking times are described, together with their advantages and weaknesses. The appendices give a mehtod 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.
