Prediction and control of stresses in concrete block
Development of criteria for prediction of thermal stresses in concrete dam construction block during cooling operations prior to grouting is outlined; new concept is presented concerning tensile stress within block which includes ratio of height of temperature transition zone to base length of block being cooled; it is shown that high temperature gradients in concrete block will lead to excessive tensile stresses resulting in cracking of block; several curves are given for prediction of maximum tensile stress as function of base length, height of temperature transition zone, temperature change, and properties of concrete.
