2), the configuration of cold and warm air-conditioning, electric heaters and other thermostatic devices, the indoor temperature should be controlled in the range of 20 ± 2 ℃;
3), general engineering can be set up in the pool, the specimen at a temperature of 20 ± 2 ℃ does not flow
Ca (OH) 2 saturated solution in the maintenance. Conditional large-scale projects should be equipped with sprinklers, indoor air relative humidity greater than 95%;
4), the standard maintenance room should be set up indoors cement mixed mortar block cabinet, cabinet should be lined with sponges and other moisturizing materials to control the humidity of sixty percent to eighty percent;
5), the standard maintenance room shall be equipped with a thermometer, hygrometer, temperature, humidity should be recorded by the person each day Twice a day (on, afternoon each one), at the same time must establish a standard maintenance room management system and strictly enforced.
6), mortar, concrete test block according to the specification standards, test block production in the final set before the use of iron nails engraved with the date of production, engineering parts, design strength level, not in the test block after the final set of writing.
Basically, all projects that use concrete pouring need to set up concrete standardized room
