Notes:
Damage parameter of concrete is widely used in design and construction of concretestructures. An experimentation method has been designed, which can simulate the initial damage bymixed initiator into concrete. Damage parameter can be obtained in laboratory with standardspecimens. But practical structure is very large. It is not rational to use this parameter in practicalstructures. So size effect on damage parameter is studied. It is concluded that initial damage andsummit damage grow with the increase of structure size, but the growth rate becomes gentle withsize increasing. When the size is larger than 500 mm×500 mm, the growth rate is less than 15‰, sothe results obtained from specimen in 500 mm×500 mm can be used for mass concrete structures
