Justification of Federation International de Beton, fib, 2000 model for elastic modulus of normal and high-performance concrete, HPC

Abstract
This article outlines an experimental and theoretical comparison between the fib 2000 model for elastic modulus of normal concrete, NC, and HPC and 144 laboratory tests. Two dimensions of specimen were studied (diameters 56 and 100 mm) and one climate (20 degreesC, sealed or with ambient relative humidity, RE, 60%). The age dependence did not seem to be well correlated between the derived and the measured elastic modulus. The fib 2000 model overestimated the elastic modulus of mature concrete and in contrast slightly underestimated the elastic modulus of young NC. As a whole, the derived modulus when using the fib model was about 110% of the elastic modulus measured at loading. A relationship to strength was found for this diversity with... (More)
