The third-point loading flexure strength test was performed on a concrete beam having a cross section of 0.15 m by 0.15 m and a span of 0.45 m. If the load at failure was 35.7 kN, calculate the flexure strength of the concrete.

The concrete's flexure strength can be calculated by dividing the load at failure by the area of the cross-section and span of the concrete beam. This gives a flexure strength of 7,276 kN/m2. This is a very high strength for concrete and indicates that the concrete structure has very good durability and strength characteristics.
