A center-point loading flexural test was performed on a concrete beam with a cross section of 100 mm * 100 mm and a span of 200 mm. If the failure load was 26.9 kN, find the flexure strength.
The center-point loading flexure strength test was performed on a concrete beam having a cross section of 4 in. by 4 in. and a span of 8 in. If the load at failure was 5,000 lb, calculate the flexure strength of the concrete.
A concrete specimen with b = d is supported at both ends 600mm apart. It is tested for flexure strength with load at midspan of 100kN and failed with a flexural stress of 52.083 MPa. What is the dimension b and d of the specimen in mm?
