1.	In design of R.C.C. structures, the tensile strength of concrete is taken as:(a) 5N/mm^2(b) 2N/mm^2(c) 0.3N/mm^2(d) 0N/mm^2I have been asked this question in unit test.Enquiry is from Properties of Concrete in chapter Building Construction of Basic Civil Engineering
Answer» Right ANSWER is (d) 0N/mm^2 The BEST explanation: SINCE concrete does not take up tensile LOADS, it is taken as zero. But IS 456-2000 recommends the tensile strength to be CALCULATED using Ft = 0.7√fckN/mm^2.
