Figure 6. Tensile strength of tensile bars exposed to water for different periods of time. The tensile
strength remained similar despite the various time periods they were exposed to water. Tensile
strength was calculated by dividing the maximum load by the cross-sectional area of the tensile bar.

Figure 7. The time between maximum load and tensile failure for different time periods of water
exposure. The time between maximum load and failure decreased as the time exposed to water
increased.
