Abstract:
Three methods for determining drying shrinkage of high-pressure steam-cured concrete block are described and results compared. A rapid method requiring only 24 hr immersion was found to be as practical as methods requiring 96 hr immersion for determining absorption and moisture losses. For measuring shrinkage, the rapid method is satisfactory provided allowance is made for the fact that the values determined are approximately twice those found in service. A device for measuring tensile strength of concrete in whole block is described and illustated. Although still under development test results were in good agreement.
