What are the main principles of standard curing room design?

The concrete standard curing room is a special house for curing concrete specimens under specific temperature and humidity conditions. At present, China's national standards stipulate that the curing of concrete specimens is: the temperature is 20 3℃ and the relative humidity is above 90%; The temperature stipulated in international standards is 20 2℃, and the relative temperature is above 95%. Experiments show that temperature and humidity are two decisive factors for the development of concrete strength. The smaller the temperature and humidity deviation, the better the comparability of strength data.

The main principles of the design of standard curing room for concrete are heat preservation, moisture preservation and water saving. The standard curing room of concrete test block is mainly equipped with constant humidity and temperature controller, air conditioner, heating plate and humidifier, and other auxiliary equipment, such as spray pipes and nozzles, and maintenance rack reservoir. Constant humidity and constant temperature controller, with the development of modern social economy, people's requirements for air temperature and humidity in industrial production environment are getting higher and higher, and the application fields of constant temperature and humidity environmental control equipment are becoming more and more extensive. Matsui industrial constant temperature and humidity machine selects international brands of compressors, refrigeration accessories and electrical control components, which are designed and manufactured in full accordance with European industrial standards and have the characteristics of reliability, high efficiency and accurate control. Units are widely used in industrial workshops, exhibition halls, archives, laboratories and other places in various industries, specializing in creating a precise industrial air-conditioning environment with constant temperature and humidity. Humanized design, multi-level capacity adjustment according to actual load, efficient operation and energy saving; Fresh air can be introduced and energy can be recovered to keep the ambient air fresh and natural; It can use all-green refrigerants R407c and R 134a to produce refrigerant products.

Water saving Because the relative humidity in the standard curing room is required to be above 95%, it needs to be sprayed to the curing room continuously, which consumes a lot of water. Besides anti-seepage and water-saving treatment, circulating water is the key to water saving. A backwater pool, a sedimentation pool and a ponding pool are arranged around the ground. The ponding pool is the highest point on the ground with a slope of 0.5%. The water return tank is also set with a slope of 5%, with the diagonal of the water storage tank as the highest point. In this way, there will be no water accumulation on the ground, but the sprayed water can quickly return to the water tank, flow back to the water accumulation pool after passing through the sedimentation tank, and be recycled without equipment in the standard maintenance room. According to the measurement, the daily water consumption is 8 kilograms.
