Crushing strength of concrete rings with a polyurea ...

2020-7-1  Nine static crushing tests of the concrete rings were performed: three tests with control samples, three tests with samples having the coating on their outer surface, and three tests with samples having the polyurea coating on their both surfaces. The limit crushing strength of a ring was defined as the highest recorded compression load. 3.1.
