THE EFFECT OF TEMPERATURE ON CREEP OF CONCRETE: A LITERATURE REVIEW

A REVIEW OF THE LITERATURE ON THE EFFECT OF ELEVATED TEMPERATURES ON THE TIME-DEPENDENT VOLUME CHANGE DUE TO LOAD (CREEP) OF CONCRETE REVEALS INCOMPLETE AND CONFLICTING EVIDENCE. SOME WORKERS HAVE FOUND A "CREEP MAXIMUM " AT A PARTICULAR TEMPERATURE RANGE; OTHERS HAVE NOT ENCOUNTERED THIS PHENOMENON. AMONG THOSE WHO HAVE FOUND IT, THEREIS LACK OF AGREEMENT AS TO WHAT THE RANGE IS. ALL AVAILABLE DATA HAVE BEEN COLLECTED, REDUCED TO COMPARABLE FORM, AND ANALYZED. THE ANALYSIS HAS BEEN REVIEWED IN THE LIGHT OF THE SEVERAL THEORIES OF THE MECHANISM OF CONCRETE CREEP. IT IS CONCLUDED THAT THE NEW RESULTS ON TEMPERATURE EFECTS ON CREEP DO NOT RESOLVE THE CONFLICTS AMONG THE VARIOUS CREEP THEORIES, BUT THEY TEND TO SUPPORT THE SEEPAGE THEORY MORE THAN ANY OTHER. MANY FACTORS AFFECTING CREEP ARE FOUND TO BE INFLUENTIAL AT ELEVATED TEMPERATURES IN ANALOGOUS FASHION TO THEIR INFLUENCE AT ROOM TEMPERATURE. THESE FACTORS INCLUDE TIME UNDER LOAD, APPLIED STRESS, MATURITY OF CONCRETE, AND MOISTURE CONTENT OF CONCRETE. /AUTHOR/
