METHOD AND APPARATUS FOR EVALUATING CRACKING OF CONCRETE DUE TO TEMPERATURE

摘要

PURPOSE:To obtain the results of evaluating cracking accurately and easily without experimental examination and temperature stress analysis on various physical values, by calculating a temperature distribution factor with a data processor from a value of temperature progress of concrete. CONSTITUTION:This apparatus is mainly composed of a temperature forecaster 1, a heat conductivity analyzer 1a, a data processor 2 such as personal computer as connected thereto, a printer 3 and a plotter 4 connected to the data processor 2 and a display device 5 connected to the printer 3. A temperature distribution factor is determine from a value of temperature progress of concrete after being deposited to evacuate the hazard of causing cracking due to temperature stress based on the temperature distribution factor as reference. A temperature distribution factor is calculated based on the value of temperature progress of concrete measured and calculated with the forecaster 1 and an analysis value of the temperature of concrete determined with the analyzer 1a, a signal is generated from the data processor 2 judging possible generation of cracking based on the temperature distribution factor and the results are shown on the display device 5.
