【 摘 要 】

The water-soluble polyurethane is widely used in repairing, waterproof and other subway and building engineering fields. But there is little information about the shear mechanical properties of water-soluble polyurethane in concrete. The new type of water-soluble polyurethane as an adhesive material, the shear mechanical properties of concrete under the composite action of pressure and shear are studied in this paper. A diagram of the relation between shear stress and horizontal displacement is drawn. And the relationship between the maximum static friction and the dynamic friction and the relationship between the shear stress and the vertical stress are obtained. It provides a scientific basis for the application of new high performance water-soluble polyurethane in a large range of engineering.
