How long do you start a new concrete floor?
Cement concrete pavement to achieve the design strength of more than 25% when the slits, generally do not destroy the principle of concrete, the next day you can cut.
According to the day pouring temperature, such as 35 ℃, can be cut off within 10h-12h.
2, the slit must be cut after the mold can be cut, the demolition of the mold there is strength requirements, because the demolition of the mold will be shock, so the demolition required to achieve the strength of 25%, which is a basic requirement of the slit.
3, according to the sand content of concrete, the surface of the concrete surface is a layer of mortar, if the cutting time is early, the machine in the above or people in the above work easy to damage the overall surface of the road surface and tectonic coefficient.
