Concrete barriers along the streets and alleys in the city are often seen placed at the roadside. From a distance, they appear vividly colored, but up close, cracks and peeling can be observed. What is the cause of the cracking in these concrete barriers?What?

   Due to the limited outdoor production site for concrete separation blocks, high temperature requirements are necessary. During the production process at various manufacturers, insufficient attention is paid to the watering maintenance during production, resulting in uneven concrete mixing, and workers fail to meet the production standards.48Hourly demolding can lead to cracking. Once cracks appear on the surface of the isolation blocks, it greatly affects the product's aesthetics. Therefore, how can we avoid and repair them during the production process?

   During production, ensure48Demold within an hour, then water spray every 2 hours after demolding. Cover and maintain after watering to prevent direct sunlight exposure. In case of cracks, first remove and smooth out the surface debris, then fill with cement and resmooth. After completely drying, repaint.
