How to prevent cracks in bailey panels

What do we need to do to prevent cracks in the bailey? The first and more important thing is to strengthen the initial curing of the concrete. After the bailey concrete is poured, the disclosure should be covered with straw mats, straw bags or plastic film in time. And sprinkle water for damp curing. In the weather with high temperature, low humidity and high wind speed, it should be covered and cured with water mist as soon as possible, and the time of maintenance should be delayed appropriately. To avoid general temperature cracks caused by the internal restraint of concrete, it is generally adopted to control the temperature difference between the concrete surface and the outside or inside to make it less than 25℃. The usual control method is: for heating and curing components, the temperature should be slow to rise and fall, so that the rising and falling temperature is not more than 10℃/h, and it is expected that the cover and demoulding will be slow to avoid excessive temperature stress; for large-volume structures, When the temperature difference between the concrete and the outside is more than night, heat preservation and maintenance should be adopted. When the director removes the mold, the temperature difference should be controlled within 25 ℃.
