Description
Technical field
The present invention relates to hydraulic engineering concrete dam guard technology field, particularly relate to a kind of frost-resistant concrete big
Dam.
Background technology
Hardening why can be gradually condensed until obtaining final strength due to cement aquation after concrete casting
Result.And the speed of cement aquation is relevant except composition material own with concrete and match ratio, additionally, go back and ambient temperature
Closely related.When the temperature increases hydration accelerate gain in strength accelerate and when temperature is reduced to during uniform temperature, coagulation
Water in soil some start freeze, gradually become solid phase from liquid phase, the water at this moment participating in cement aquation decreases, water
Change slowed down gain in strength the most slack-off.Temperature continues to reduce when the water that be present in concrete becomes ice i.e. complete completely
When entirely being become solid phase by liquid phase, cement aquation substantially stops the intensity of now concrete and will not increase again.Owing to water becomes
After ice, volume about increases 9%, produces the swelling stress of about 2.5MPa simultaneously, this stress being internally formed commonly greater than concrete
Initial intensity value make concrete be subject to destruction (i.e. early freezc destruction) in various degree.In addition also can be after water becomes ice
Produce the ice slush that granule is bigger on aggregate and rebar surface, weaken cement mortar and aggregate and the cohesive force of reinforcing bar.When ice slush melts
After, also can form various space at inside concrete, and reduce the durability of concrete.
