Since the cement board is heated, the various materials expand and generate force on each other, and the result is a cracking phenomenon.
Simply and bluntly use netizens to explain: cement can not be directly burned, rural areas generally dig out a piece of cement in the pit to burn, otherwise the soil under the cement heat vapor has no place to emit, will definitely explode
