Description

Technical Field

[0001] The invention relates to the technical field of highway detection, in particular to a constant temperature curing box for cement test pieces. Background Art

[0002] Cement specimen curing is to artificially create certain humidity and temperature conditions so that the newly poured concrete can harden and increase its strength normally or accelerate its hardening. The reason why concrete can gradually harden and increase its strength is the result of cement hydration, and cement hydration requires certain temperature and humidity conditions.

[0003] At present, constant temperature water curing box is the main equipment for testing the performance indicators of cement products. Cement specimens must be cured under the specified standard temperature and humidity, and the test data can truly reflect the quality of cement products. Generally, cement specimens are cured using water curing equipment. However, in the process of water curing, because water is very easy to absorb and dissipate heat, it is easy to cause rapid temperature changes during the curing process. The existing temperature control method mostly uses a single electric heating rod to heat the entire curing box. This heating method is inefficient and easily causes uneven temperatures between the upper and lower parts. In addition, the cement specimens cured in the curing box are not easy to be removed from the inside of the curing tank. For this reason, we propose a constant temperature curing box for cement specimens. Summary of the invention

[0004] The purpose of the present invention is to provide a constant temperature curing box for cement specimens to solve the problems raised in the background technology.
