Abstract

The invention relates to a device for a concrete compressive creep test in a high-temperature environment. The device comprises a traditional creep test device, marble cushion blocks, an upper cover, a baking oven housing, a baking oven heating device, a lower cover, a cover opening hole and a footstand. The baking oven heating device has a cylindrical structure. The middle of the cylindrical structure is provided with a through hole. The through hole structure matches with a concrete test piece. The concrete test piece is placed at the through hole. The top of the baking oven heating device is provided with the upper cover. The bottom of the baking oven heating device is provided with a lower cover. The upper cover and the lower cover produce sealing effects. One of the marble cushion blocks goes through the upper cover and is located between a large cushion plate and an upper pressing plate. The other one of the marble cushion blocks goes through the lower cover and is located between a cushion plate and a force sensor. The device can realize a concrete compressive creep test in a high-temperature environment in the fields of civil engineering, hydraulic engineering and mine engineering. The device is obtained by device addition and reconstruction of the existing compressive creep tester, has a low cost and is convenient for operation.

Description

technical field [0001] The invention belongs to the technical field of concrete indoor test, and in particular relates to a concrete pressure creep test device under high temperature environment. Background technique [0002] Creep is the characteristic that the strain of concrete increases continuously with time under long-term stress. Concrete creep can alleviate the shrinkage temperature stress of early-age concrete, and may also cause long-term prestress loss of structural concrete. Accurately predicting the creep deformation of structural concrete has important academic significance and engineering application value. [0003] At present, the test devices used to measure the creep of concrete under pressure at home and abroad are all carried out at room temperature, or under short-term high temperature conditions, and there is no test device for the creep of concrete under long-term high temperature conditions. Some special concrete structures are located in a high-tem...
