Investigation of Nonmetallic Waterstops. Evaluation of the Effect-of-Alkalies and Accelerated Extraction Tests. Report 2.

Abstract

Nineteen nonmetallic waterstop materials, consisting of 10 standard or cold-weather PVC, two polyethylenes, and seven natural or synthetic rubbers, were subjected to the accelerated extraction and effect-of- alkalies tests. The accelerated extraction test did not affect the tensile strength of the standard-grade PVC, but did affect the tensile strength of all the other materials tested. The accelerated extraction test affected the ultimate elongation of all the materials tested. The changes in weight and hardness in the effect-of-alkalies test were linear for the two times of observation used. The change in thickness was due to experimental error only, and all the materials tested met the change-in-hardness requirement of the effect-of-alkalies test. (Author, modified-PL)
