Can cement pavement withstand 1 10,000 kg in 24-hour high temperature weather?
Cement construction: The temperature below 10℃ is too low, which affects the hydration speed, slow strength growth and long curing time. When the temperature is over 45 degrees, the hydration of cement itself is an exothermic process. If the ambient temperature is too high, it is easy to cause rapid evaporation of water, difficult maintenance and easy to cause dry cracking. But in special circumstances, just pay attention to saving water. Temperature resistance of concrete members: ordinary cement concrete is below 1000℃, which has no effect on concrete. Use concrete in high temperature environment (above 1000 degrees, high-alumina cement can be used as concrete, which can resist heat 1350 degrees).
10cm thick concrete floor is mainly determined by the bearing capacity of compacted soil layer. General 10cm concrete cushion can bear 400 kg/m2. If it is 10cm precast floor slab, it can bear 150 kg/m2. If it is a concrete floor with 10cm, it can bear 150 kg/m2. The bearing capacity of concrete foundation will be influenced by foundation bearing capacity, concrete grade, concrete thickness and design form.
