Compression Characteristics and Constitutive Model of Low-Exotherm Modified Polyurethane Grouting Materials
In permafrost regions, ordinary polyurethane grouting materials are not suitable for the repair and reinforcement of road engineering due to the release of a large amount of heat during the reaction process. In this study, the polyurethane grouting material is modified by changing the catalyst, blow...
