Want to know a method to reduce concrete crack it? I'll tell you!

Time as fleeting, and enter the annual summer season, the summer heat, thunderstorms and other weather factors complex, to bring a lot of trouble concrete construction. Hot season is the high incidence of concrete cracks, of course, cause a lot of concrete cracking factor. Today, we have prepared a common precaution against hot season concrete cracks and small partners to share to you, welcome onlookers Oh!

1. cooling shade
Yard of sand and gravel aggregate to be taking the necessary measures to shade, water pipe should be buried in the ground, water storage tank should be treated shading, gravel sprinkler to spray cooling process. Strict temperature control of cement, concrete extruder temperature lower temperature. Concrete mixer with clean connectivity cool bar.

2. staggering production
The hot season, should avoid the midday 12:00 - 16:00 the sun is high time pouring concrete. Before pouring the concrete, response templates, and construction work on site watering cooling, prepare enough maintenance materials, such as fabric care, water pump.

3. Determine the appropriate slump and water-cement ratio
To improve aggregate gradation, control of water-cement ratio, select retarding additives and reasonable construction process. It should be emphasized that the mixing station should be based on the day's weather conditions, distance from the expected time for unloading and transportation of concrete to determine a reasonable water-cement ratio and slump, not a fight in the end with the ratio.

The conservation is important
Full-time person in a timely manner has been pouring sprinkler maintenance of concrete structures, particularly concrete structures exposed to the sun in the construction, its surface must be covered with "mask" overwrite conservation, maintain humidity stable concrete. Secondary plaster, concrete form removal is also important strength of 70%! It should be noted that, to pouring concrete factory are "semi", post curing of concrete, form removal and other post work is very important and requires mixing station construction site and have good communication and cooperation, the total package of concrete cracking problems all tend to attach to the mixing station business and unreasonable.
