1.	The flexural strength (or modulus of rupture) is obtained for the first peak load, Pmax as _______________(a) Pmax * L/bd^2(b) Pmax/Ld^2(c) Pmax * L/bd(d) Pmax/L/bd^2I have been asked this question in unit test.The origin of the question is Flexural Strength of Concrete topic in section Testing of Concrete of Concrete Technology
Answer» Right choice is (a) Pmax * L/bd^2 The explanation is: It should be noted that the value obtained may be significantly DIFFERENT from that obtained in a CONVENTIONAL test CARRIED out under load control, where the SPECIMEN fails at the PEAK load.
