EXPERIMENTAL STUDY AND ANALYSIS FOR PREVENTING THERMAL CRACKS OF LARGE CYLINDRICAL REINFORCED CONCRETE SILO

Abstract

This experimental study has been conducted on preventing cracks induced due to the heat of hydration of cement during construction. A large cylindrical reinforced concrete silo was used to assess the effect of several improved construction methods. Numerical analysis with high accuracy was conducted for the measured stresses, temperature, etc.. This numerical method, in which FEM was used can predict the thermal stresses of practical significance. It was noted that more detailed conditions on surface heat convection such as, influence of weather and curing conditions, must be considered to predict the actual value.
