Description

<p>The purpose of this study is to reduce the environmental load of plastic grout, which is mainly used as void-filling material, by suppressing the increase in the pH of the surrounding water when it is placed in water. In this study, especially for high strength type plastic grout （compressive strength：24N/mm2 or more）, the amount of cement in the binder was reduced as much as possible, and a large amount of admixtures such as ground granulated blast-furnace slag and fly ash were used. As a result, in the high strength type, it was possible to suppress the elution of calcium hydroxide produced in the hardening process due to the hydration reaction of cement. It was confirmed that the increase in the pH of the surrounding water when the plastic grout was placed in water could be suppressed.'</p>
