Crushing Strength Of Concrete Rings With A Polyurea

Jul 01, 2020 The average crushing strength of the control samples (with no coatings) was 60.5 kN. The graph in Fig. 18 indicates that values of the crushing strength for samples A-1 to 3 (both individual and average values) are apparently higher than for samples C-1 to 3 and E-1 to 3. This allows us to conclude that crushing strengths of the rings coated on both sides are the highest and thereby this way of application produces a
