How to arrange concrete mixing plant in rainy season

 First of all, we need to understand the weather forecast in the future 2~3 days, adjust the concrete mix ratio according to the weather conditions and the progress of the construction, and adjust the construction process appropriately. The concrete quality can be guaranteed by avoiding the damage of concrete to the maximum extent.

Secondly, we should strengthen the management of raw materials, less inventory, timely clean-up inspection of raw materials on the damp metamorphism of raw materials, to prevent damp metamorphism in the concrete mixing station, closed production, management measures on entering the sand. Quality inspection personnel should promptly determine the moisture content of sand and gravel, adjust mix ratio, from the source to ensure the quality of concrete;

Concrete mixing plant equipment in the production operation, if wait for pouring concrete during a sudden rain, under the concrete mixer truck hopper parts should be covered a layer of plastic sheets, so as to avoid the rain into the tank, after concrete pouring covered in time, prevent the rain shower concrete surface, pot-holed concrete surface, reduce the smoothness of concrete and actual strength;

The produced concrete strict acceptance by quality control personnel, qualified rear can play, rain should make concrete slump and slump is smaller than the actual 1cm, such as that does not meet the requirements of timely notification of concrete adjust batch plant operator station;

Finally, at any time, the concrete specimens of standard curing room of constant temperature and humidity equipment to check, to ensure that the humidity is above 90%, the maintenance condition between 17-23 degrees of temperature.
