Bi-linear relationships between drying shrinkage and mass loss of concrete are known. Drying shrinkage tests of concrete with various materials and mix proportions are conducted, and inclinations (α) and X sections (β) of the second lines of drying shrinkage and mass loss are worked out, and it becomes possible to estimate α and β from materials and mix proportions of concrete. Using the results of investigation, an estimation method of drying shrinkage of concrete are proposed.
