2. Cement standard curing box: the temperature is 20 65438 0℃ and the humidity is greater than or equal to 90%.
3. Concrete room: the temperature is 20 2℃ and the humidity is 95% or higher.
Curing room is an experimental facility that can adjust the temperature and humidity of the internal environment, and is used for curing concrete test blocks, cement test blocks, mortar, thermal insulation materials, coatings, structural adhesives, etc. To ensure that they meet the test requirements. Different specimens and different tests have different requirements for the temperature and humidity of the curing room.
Among them, the National Standard of People's Republic of China (PRC) GB/T5008 1-2002 jointly issued by the Ministry of Construction and the General Administration of Quality Supervision, Inspection and Quarantine stipulates that the temperature of standard concrete curing room is 20 2℃ and the humidity is above 95%.

Maintenance requirements of cement curing room
1, according to the standard curing test block, should be in the environment of temperature 20+/-5℃ let stand for one day and night to two days and nights, and then number, dismantle. Immediately after form removal, it should be placed in a standard curing room with a temperature of 20 2℃ and a relative humidity of over 95%.
2. The specimen in the curing room should be placed on the bracket, and the spacing between the specimens should be kept at least 10 ~ 20 mm, and the surface of the specimen should be kept moist, and it is not allowed to be washed directly with water. The standard curing period is 28d.
3. Each sample must be marked with the sample number. If the temperature and humidity are abnormal, measures should be taken immediately, and the person in charge should be reported and recorded. The stay time of the experimenter in the standard curing room should not be too long, especially when the temperature difference with the outside is large.
4. Change the maintenance water in the pool every two weeks, and change the water before cultivation. Specimens should be sent to the relevant testing units in time, and taken out of the pool the day before the inspection, so that it can be naturally dried.
