Cement test part curing box with uniform temperature and humidity

Abstract

The invention discloses a cement test part curing box with uniform temperature and humidity. The cement test part curing box comprises a box body (1), wherein a curing device (2) is arranged on the upper portion of the box body (1), the curing device (2) comprises a pool maintenance box (21) and a moisture curing box (22), and a plurality of circulating water tanks (211) are arranged in the pool maintenance box (21) from top to bottom; a plurality of bedplates (221) are arranged inside the moisture curing box (22) from top to bottom, a nozzle (222) is arranged at the top of the moisture curingbox (22), and a humidifier (223) is arranged below the nozzle (222); and the lower part of the box body (1) is a constant-temperature water circulation device (3), the constant-temperature water circulation device (3) comprises a constant-temperature water tank (31), a water temperature control instrument (32), a cold storage water tank (331), a refrigerator (33) and a circulating water pump (34). According to the cement test part curing box, the uniform and stable curing water temperature can be kept, the temperature and humidity of the wet air to be uniform and stable can be quickly restored under the condition that a box door is frequently opened, and the cement test part curing box is suitable for curing the strength test part and the setting time and the stability test part of the cement.

Description

technical field [0001] The invention belongs to the field of testing equipment for building cement test pieces, in particular to a curing box for cement test pieces with uniform temperature and humidity. Background technique [0002] When testing the quality of cement products, it is necessary to make cement samples into test samples, and to maintain them in a standard temperature and humidity environment. The uniformity of temperature and humidity in the curing box not only affects the monitoring of the curing environment, but also affects the curing environment. The test results of the later test pieces will be affected, and even the situation of "different results when placed in different positions" appears. The change of the heat of hydration produced by the cement specimen and the humid curing environment increase the difficulty of adjusting the temperature and humidity of the curing box. [0003] For the water curing of strength test blocks after demoulding, when the ...

Problems solved by technology

Regardless of the moisture cycle or the water spray cycle, if one type of cycle is used alone, the temperature and humidity of the curing box are not easy to recover quickly when the specimen is taken and placed and the door is frequently opened, and it is difficult to adapt to the setting time of cement and the stability of the specimen. conservation
