Description
Technical field
The present invention relates to Construction of Civil Engineering fields, and in particular to a kind of anti-drying shrinkage template of mass concrete construction.
Background technology
Simple, stress performance is good due to preparing for concrete, it has also become one of widest engineered building materials of modern Application.
With the rapid development of modern social economy, heavy construction structure is increasing, and mass concrete is in water conservancy, road bridge
It is used widely in the fields such as beam, building.
The design feature of mass concrete mainly has following：1）Structure tensile strength be far below compression strength, only its
1/10 or so, structure stretch-proof deformation energy force difference；2）Structure section size is big, is pouring initial stage, and hydrated reaction of cement is violent,
Rate of heat production is more than structure rate of heat dispation, leads to heat build-up, and structure modulus of elasticity is smaller at this time, creeps larger, leads to it
Caused compression is also smaller, but in subsequent temperature-fall period, concrete bullet mould is larger, creeps smaller, in the shadow of extraneous factor
Under sound, structure will produce a certain amount of tensile stress, easily influence structure safety；3）Mass concrete extraneous medium is often air,
And the variation of extraneous medium temperature is easy to show to cause certain tensile stress in structure, influences structure operation；4）Large volume coagulation
Soil is often plain concrete construction, and the tensile stress so as to cause its generation is born by concrete itself entirely.
Due to the These characteristics of mass concrete, in its Practical Project, it is contemplated that the complexity of construction and extraneous factor
Property, structure usually will appear thermal cracking, desciccation crack, these cracks are once superimposed other adverse factors, then can influence structure
Normal safe operation.
These distress in concretes lack necessary moisture often caused by curing period, and concrete surface humidity is caused to lack
It is weary, in addition the reason of temperature is spread, then easy to produce desciccation crack.This phenomenon shows more bright in mass concrete
It is aobvious, therefore, how wet curing is carried out to concrete in the maintenance stage, is present practical work to control surface temperature and humidity
The important means of distress in concrete is solved in journey.
Present concrete curing mostly uses thermal insulation material cooperation template, and watering maintenance, this watering is uneven, due to wet
Degree is poor, wetness control is inevitably resulted in, to generate micro-cracks；In addition, template proximate concrete, template can not play humidity
The effect of holding, therefore, it is impossible to solve the crack problem of mass concrete from construction technology.
