1.	The coefficient of thermal expansion of concrete is similar to that of steel, eliminating large internal stresses due to differences in thermal expansion or contraction.(a) True(b) FalseThe question was asked in a national level competition.The query is from R.C.C. Work and Amount topic in division Different Type Roofs, R.C.C of Civil Engineering Drawing
Answer» Correct answer is (a) True Explanation: An average value for the COEFFICIENT of THERMAL expansion of concrete is about 10 millionths PER degree Celsius (10×10-6/C), although values RANGING from 7 to 12 millionths per degree Celsius have been observed.
