What do we need to do to prevent cracks in bailey panel? The first and most important thing is to strengthen the initial curing of the concrete. After the Beret 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 as soon as possible, sprayed with water mist for maintenance, and the time for 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°C.
The control method is:
For heating and curing bailey panel components, the slow rise and fall temperature should be adopted, so that the rise and fall 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 concrete and concrete When the outside temperature difference is higher than that at night, heat preservation and maintenance should be adopted. When the director removes the mold, the temperature difference should be controlled within 25 ℃.
To avoid temperature cracks caused by the internal restraint of the concrete, the temperature difference between the concrete surface and the outside or inside is generally controlled to be less than 25°C.
The use of moderation is:
For the heating and curing bailey panel components, the rising and falling temperature should be slow, so that the rising and falling temperature is not greater than 10℃/h, and it is expected that the cover and demoulding will be slow to avoid excessive temperature stress; For the night volume layout, when the temperature difference between the concrete and the outside is large, heat preservation and maintenance should be adopted, and the temperature difference should be controlled within 25 ℃ when the director removes the mold.
