Along with socio-economic development, the step of Development of China's Urbanization is increasingly faster, and concrete floor pours and becomes
It is seen everywhere, but on the most a lot of building site, concrete floor surface occurs that the situation in crack is the most serious.
The reason generally resulting in concrete floor cracking is: concrete floor pours early stage, due to hydration heat of cement
Release, can cause temperature rise cause volumetric expansion, after hydration heat of cement rate of release slows down,
Base plate volume contraction is caused owing to backplate surface heat radiation can cause temperature to decline.The expansion of concrete floor with
Contraction is not to occur along whole sectional uniform, heats up when expanding due to the thermolysis on surface, surface
It is slow that temperature rises, and it is fast that middle portion temperature rises, and causes portion in the soleplate to form thermograde with surface,
Thermograde shows that the most greatly the bending that backplate surface should occur under the effect of temperature is the biggest, receives constraint

During 25 degree of temperature difference, the end of 10cm, is the most easy to crack, it is therefore necessary in the range of measuring surface certain thickness
Temperature difference obtains thermograde, instructs insulation, moisture-keeping maintaining with this thermograde.
And, the maintenance of base plate is only rested on and carries out surface simple covering and heat insulating layer with artificial by current great majority
Arbitrarily sprinkling water maintenance, when this maintenance process is starting maintenance of sprinkling water, and when needs to add a cover heat-insulation layer,
