A self-contained casting device was developed to make strand tests with ten units simultaneously cast under constant tension. They are all cured at the same temperature and the ends of the strands are so contoured that they will fit into adapters in Instron jaws to give rapid and reproducible tensile results. This apparatus minimizes the role of the operator and reduces several of the variables associated with the present ASTM strand test. The standard deviation is less than 6. Author
