Abstract

The invention provides a multifunctional curing box for mass concrete. The multifunctional curing box comprises a box body with a door, four cavities and a refrigerating and heating device mounted at the bottom of the box body with the door, wherein the four cavities are defined by a horizontal thermal-insulating water-resisting layer and a vertical thermal-insulating water-resisting layer which are perpendicular to each other and mounted inside the box body with the door; a standard curing box is arranged in the first cavity; a curing box with the highest temperature of 30 DEG C is arranged in the second cavity; a curing box with the highest temperature of 60 DEG C is arranged in the third cavity; a curing box with the highest temperature of 80 DEG C is arranged in the fourth cavity; the refrigerating and heating device comprises a refrigerating device, a liquid collecting box and a heating device, which are mounted at the bottom of the box body with the door. The multifunctional curing box disclosed by the invention can be matched with mass concrete samples at the matched temperature, cannot limit the size of the sample, has the characteristics of being economic, safe, environment-friendly and energy-saving, can provide relatively complete data, and further provides experimental data and conditions for research about how to control temperature stress cracks of the mass concrete caused by hydration heat in the early stage and development of the concrete mechanical properties.

Description

technical field [0001] The invention relates to a concrete curing box, in particular to a multifunctional curing box for large-volume concrete. Background technique [0002] In recent years, with the construction of large-scale infrastructure and water conservancy projects such as the Three Gorges Project and high-rise buildings, and the scale of engineering construction has become larger and larger, the use of large-volume concrete has become indispensable. Correspondingly, mass concrete structures appear in large numbers in general industrial and civil buildings. At present, the cracking phenomenon of commercial concrete and high-fluidity concrete commonly used in construction has been relatively common. In addition, the fineness of the cement produced now greatly increases the heat release rate, which greatly intensifies this phenomenon compared with the past. The problem of temperature cracks in volumetric concrete has become increasingly prominent and has become a univ...
