摘要：

The effect of low temperature (-35 degrees C) on the mechanical properties of concrete with different strength grade such as compressive strength, flexural strength, splitting tensile strength and elastic modulus was studied. The results showed that all of the mechanical properties were improved at -35 degrees C. It was also can be found from the tests, as the strength grade increased, the growth ratios at -35 degrees C of compressive strength, flexural strength and splitting tensile strength decreased. But the growth ratio of elastic modulus increased with the increasing of strength grade.
