A STUDY ON THE EFFECT OF CONTROL METHOD OF THERMAL CRACKING IN MASS CONCRETE SLAB

There are many methods ranging over design and construction to control thermal cracking in mass concrete structures. However, it is necessary to evaluate the effect of each method quantitively in order to control thermal cracking effectively.In this study the equations to express the effect of the methods, for example, concreting temperature, curing method, and lift separation, to control thermal cracking in mass concrete slab are obtained in the result of thermal stress analysis. The most effective method according to the size of the structure and the external restraining level can be selected easily using these equations.
