A Study on the Influence of Finish on Drying Shrinkage of Concrete

Abstract

Concrete cracks due to drying shrinkage. Many srudies on drying shrinkage have been so far. But many of them are on the shrinkage of concrete itself, and there is very little researches on shrinkage of concrete with surface finish. Generally buildings are covered with finishes in many cases. Hence, in order to control the crack due to shrinkage of a concrete structure, it is necessary to grasp the behavior of concrete shrinkage with surface finish. Then, this study applied various finish to the test specimens of concrete, and investigated the influence of the finish on drying shrinkage of concrete. As the results, it was clarified that the finishes strongly affected the drying shrinkage of concrete.
