Description
Technical field
The utility model belongs to technical field of concrete construction, is specifically related to the technical field of a kind of concreting in cold weather.
Background technology
Why gradually condensing hardening after concrete batching system pouring, until obtaining final strength, being due to hydrated cementitious
The result of effect.And the speed of cement aquation is except outside the Pass composition material own and match ratio have with concrete, also with outward
Boundary's temperature is closely related.Hydration is accelerated when the temperature increases, and gain in strength is accelerated, and when temperature is reduced to 5 DEG C of degree
When following, hydration reaction speed close to halted state, gain in strength slowly, when temperature less than 0 DEG C spend when, if
Do not mix antifreezing agent, the water being present in concrete some start freeze, gradually liquid phase (water) is become solid phase (ice),
Namely complete when being become solid phase by liquid phase, cement aquation stops substantially, and now the intensity of concrete will not increase again.
After becoming ice due to water, volume about increases 9%, produces the swelling stress of about 2.5MPa simultaneously, and this stress is commonly greater than mixed
The initial intensity value being internally formed of solidifying soil, makes concrete be subject to destruction (i.e. early freezc destruction) in various degree, seriously
Affect concrete quality.Additionally, after water becomes ice, the bigger ice slush of particle also can be produced on aggregate and rebar surface,
Weaken the cohesive force of cement mortar and aggregate and reinforcing bar.After ice slush melts, also can form various space inside concrete,
And reduce the durability of concrete.Thereby ensure that the curing temperature of concrete, accelerate the hydration reaction of concrete, make intensity
Reach design as early as possible and require significant.
Existing reinforced concrete member winter construction maintenance measure typically uses insulation material to cover and Boiler Steam is supported
Protecting, existing maintenance measure cost is high, some maintenance effect differences, and is difficult to operation.Under especially outdoor strong wind weather,
Covering is difficult fixing, is easily started.Therefore, design is a kind of easy to make, installs simple cold weather concrete maintenance and arranges
Applying method is necessary.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, provides one suitable
