Concrete is a kind of construction material that in civil engineering, purposes is the widest, consumption is maximum,
Basic too busy to get away concrete in modern architecture.Concrete can enter according to different character
The classification that row is a variety of, although it is as a kind of durable material, but its essence is a kind of
Porous material heterogeneous, at media such as carbon dioxide, water, chloride ion, sulfate
Under corrosion function, and the impact of inevitable foeign element, concrete can accelerate the failure,
Service life shortens.The most significantly show as intensity reduction, deformation, fracture, air slaking,
Alkali-silica reaction etc..
Xoncrete structure in use due to by environmental load effect, fatigue effect,
The impact of the unfavorable factor such as corrosion effect and material aging, structure will be inevitably generated
Damage accumulation, degradation resistance, even result in burst accident.In order to be effectively prevented from burst
The generation of accident, the service life of extending structure, it is necessary to this class formation is carried out real-time
" healthy " monitors, and repairs in time.
Whether change inside xoncrete structure to detect, generally bury in concrete
Entering sensor, embedded-type sensor needs to have with concrete in material and is closer to
Thermal coefficient of expansion, to reduce the impact of temperature stress.The two also should have good bonding,
To ensure compatible deformation, cooperation.Additionally, the size of sensor should also be as having limited
System, should not produce the biggest shadow to the physical property of sensor surrounding concrete and seriality
Ring.Therefore, the application of embedded-type sensor is greatly limited.Embedded-type sensor
Apply another limited major reason is problem in its in service life.Making of xoncrete structure
Be generally 50 years with the life-span and even go up a century, and at present embedded-type sensor stability and
Reliability is typically only capable of maintaining about 15 years, and embedded-type sensor is owing to being embedded in knot
It is difficult to inside structure directly be replaced.Therefore, it is difficult to structure is continued after sensor ageing
Continuous monitoring.For xoncrete structure embedded-type sensor, durability deficiency becomes
Limit its bottleneck problem of application further in xoncrete structure is monitored, it would be highly desirable to solve.
