This concrete adiabatic temperature rise testing arrangement temperature sensor lays at concrete sample center, interior heat -preserving container and outer heat -preserving container peripherally, and second grade heating tracing adds the thermal tracking than the one -level has apparent an advantage, can the whole interference and the hysteresis of air belt to following the tracks of the heating that receives outside temperature of fine solution concrete adiabatic temperature rise testing arrangement, lay two -stage tracking hot plate at outer bucket and interior barrel of periphery promptly, and it is by resistance wire and resistance area coiled, copper foil that surface coating one deck 0.2mm favors.
Description
Technical field
The utility model relates to Adiabatic temperature rise of concrete field tests, is specially a kind of Adiabatic temperature rise of concrete proving installation.
Background technology
Mass concrete, in China's modern construction particularly Hydraulic and Hydro-Power Engineering construction, occupies very consequence.Concrete is the hard brittle material that a kind of heat conductivility is very low, as 15 meters of thick arch dams are scattered and disappeared 95% heat about need 2 years, for 150 meters of thick gravity dams, the same heat that scatters and disappears then needs 200 years.Large volume concrete structural engineering often forms larger temperature stress in construction time and runtime and causes the cracking of structure, affects the normal utilization of buildings, even affects the people's lives and property safety.Concrete adiabatic temperature rise affects mass concrete to produce one of important thermal parameters of temperature stress, and it refers under adiabatic conditions, due to the temperature that hydration heat of cement institute heat-dissipating amount makes concrete raise.The factor affecting Adiabatic temperature rise of concrete and temperature rise rate thereof is a lot, as Binder Materials (cement, flyash etc.) composition and consumption, match ratio and aggregate kind, hydration reaction initial temperature etc.The method measuring Adiabatic temperature rise of concrete has two kinds, and one is direct method, namely directly measures with adiabatic temperature rise testing equipment; Another kind is indirect method, namely first measures hydration heat of cement, then calculates adiabatic temperature rise according to hydration heat, concrete specific heat, unit weight and cement consumption.But direct method is comparatively accurate.Adiabatic temperature rise equipment domestic at present mainly introduces the equipment of the state such as Europe and Japan, building system of Tsing-Hua University adopts a Virtual Instrument Technology adiabatic temperature rise instrument, but this instrument can not ensure adiabatic condition, also there is the phenomenon that temperature declines in the phase after experiment.Department of Water Conservancy of Tsing-Hua University have developed the heat adiabatic temperature rise tester based on the thermal insulation of same field in 1996, and this instrument adopts two secondary tracking heatings, and measuring accuracy is no less than overseas equipment, but the part that simultaneously also comes with some shortcomings.In recent years, along with thermometric instruments precision, the operational speed of a computer raising and automatically control, the development of data visualization that computer graphics is brought, make Adiabatic temperature rise of concrete test macro have the opportunity further developed.
Utility model content
