The main principles of standard curing room design are heat preservation, moisture preservation and water saving.
The following equipment is required:
(1) For houses with thermal insulation requirements, the area of standard curing room shall be determined according to the project size, and the minimum shall not be less than.
5㎡；
(2) The standard curing room for placing concrete, cement mortar and cement mortar specimens mixed with plasticizer should be equipped with air conditioning.
Or a constant temperature device such as an electric heating rod, so that the temperature in the curing chamber is controlled within a specified range;
(3) The curing room should also be equipped with spraying or humidifying device, so that the indoor relative humidity is greater than 95%, or the temperature is 20 2℃.
Curing in immobile saturated solution of calcium hydroxide;
(4) The specimen in the curing room should be placed on the bracket with a spacing of 10 -20mm, and the surface of the specimen should be kept moist and cannot be straightened by water.
Take a bath;
⑤ A specimen cabinet (or curing box) of cement mixed mortar should be set in the standard curing room, and the cabinet should be lined with insulation materials such as sponge.
Materials to control 60%-80% humidity;
⑥ Thermometer and hygrometer should be configured in standard curing room.
