Thermal expansion and Shrinkage of concrete and Steel bar

The success of analyzing the behavior of reinforced concrete structures at elevated temperature greatly depends on how accurately certain thermal properties, especially thermal expansion, specific heat and density thermal conductivity can be determined in a wide temperature range. In this Paper, in order to Predict the behavior of reinforced concrete structure in fire hazards thermal expansion characteristics of normal concrete are formulated through experimental investigation.
