Forced mixer summer construction water requirements

Summer temperatures are high, weather is variable, and there is more rain, which will have some impact on the construction of forced mixers. Due to the phenomenon that the newly poured concrete may have an accelerated condensing speed and a decrease in strength, the concrete pouring, trimming and maintenance work should be particularly careful. Jianxin Machinery recommends that you analyze the reasons in time, take effective control measures, reduce adverse effects, and ensure the quality of construction in summer.

In the hot season or when concrete is to be used for pouring large-volume structures, cold water can be used instead of some of the mixing water. The exit temperature, pouring temperature and temperature during pouring of the bulk concrete mix should be monitored and tested at least 2 hours. Concrete pump pipes can be covered with straw bags and other materials and often sprayed with water to keep them moist to reduce the temperature rise of concrete mixes due to transportation. For high-strength concrete, it is best to choose to work at night or on cloudy days. Take the following measures: 1 Set up the awning used by the concrete transport vehicle on the site; 2 Wrap a 30mm thick wet water sponge on the vertical pipe of the concrete pump, and apply the wet water sack on the horizontal pipe exposed to sunlight; 3 in concrete mixing Ice water is added to reduce the high temperature generated after concrete is poured. On the first day or two after concrete pouring, the concrete should be kept in a fully wet state, and the curing time specified by national standards should be strictly observed.
