Heat caused by hydration of cement is one of the major problems in
construction of RCC dams. Several solutions have been suggested to
address this issue and control the heat till now. Placing contraction joints
in RCC dams is one of the ways to control the thermal gradient and stress.
Tensile stresses and hydration heat can be predicted and controlled by
determining contraction joints distance. In this study, the influence of
length and depth of the concrete dam on tension and hydration heat is
studied. In sections with different depth of concrete, the distance between
contraction joints (monolith length) can be determined based on
hydration and maximum of tension. This will speed up the construction
of the dam and reduce administrative costs.
