ZERO SHRINKAGE OF AV-100 CHEMICAL GROUTDUE TO CONSISTENT RELATIVE HUMIDITY IN SOILS

September 28, 2018

chemical grout is often used in the soil environment as a sealing agent to prevent water infiltration into engineered structures or leakage from water-carrying vessels. These grout formulations shrink when dehydrated, and could potentially lose their sealing capabilities if desiccated. It has been established earlier in this study that the soil environment remains near saturation (100% RH), even in arid environments. Laboratory analysis was undertaken to determine if fully-hydrated grout loses water under high RH conditions similar to those found in the soil.
