Description
Tensile creep property of concrete is necessary to avoid thermal cracking in mass concrete structure. In this paper, tensile creep experiments with ordinary portland cement concrete, B type of blast furnace slag cement concrete and C type of fly ash cement concrete were carried out, and the differences of tensile creep properties were investigated in such three types of concrete.
The results are as follows.
1) With instantaneous elastic coefficient, C type of fly ash cement concrete is smaller than ordinary portland cement concrete but larger than B type of blast furnace slag cement concrete.
2) With specific tensile creep, C type of fly ash cement concrete is much larger than ordinary portland cement concrete and the same as B type of blast furnace slag cement concrete with regard to the loaded ages 15th, 25th day but larger than this concrete with regard to the loaded age 5th day.
3) With the total effect about avoiding thermal cracks, the order is fly ash cement concrete type C, blast furnace slag cement concrete type B and ordinary portland cement concrete.
