? A video caught people's attention. A young man in Zunyi, Guizhou set up a stone to roast fish on the concrete floor of his yard. As a result, he didn't expect the concrete floor to suddenly explode. This ending was really caught off guard. One second I was expecting delicious grilled fish, and the next I was facing a life-and-death crisis: the concrete ground exploded. Fortunately, there were no casualties when watching the video. This is a blessing. In recent years, we can often see the news that people barbecue on the concrete floor and the concrete floor explodes. We should know that the cement floor will explode when it encounters high temperature, so we should cook and work at high temperature on the cement floor by luck, and pay attention to protecting our own safety.

With the improvement of living standards, everyone likes to eat something delicious, and at home or go out for a picnic, we can mash up the delicious food we want. Generally, barbecue is the main way, but be careful not to cook on the concrete floor, which means that the concrete floor should not be directly exposed to high temperature. There is a barbecue grill, and charcoal is burned in the barbecue grill, so the concrete floor will generally not explode. Therefore, we must be careful not to put the fire source on the concrete floor, which is too dangerous and easy to explode and hurt our own safety. As for why the cement ground exploded at high temperature, according to my limited knowledge and the knowledge I learned on the Internet, I think it is mainly because the cement ground will expand at high temperature, and the explosion points of different materials are different. After the cement ground meets high temperature, it will be heated and expanded sharply, and finally it will reach the critical point, resulting in the explosion phenomenon.

? I think there is another explanation on the Internet. This explanation is that there is water in the cement ground. After the cement ground is heated, the water evaporates into steam, and the cement is dehydrated. The steam is in the cement ground, and the cement ground is sealed. This will lead to the pressure in the cement ground rising to a critical point, and finally the cement ground will explode. There is some truth in this explanation. I don't specialize in the specific explosion principle, and I'm not sure. I specialize in it, but as far as the online explanation information is concerned, it is roughly the above two explanations. In a word, the main reason why the cement ground will explode is the high temperature, and the pressure on the cement ground is high, which leads to the explosion.

The explosion on the concrete floor is still very powerful, which is very easy to hurt people, so you should be careful not to directly heat it on the concrete floor at ordinary times. If you want to barbecue and cook delicious food like grilled fish, you can choose a suitable place to make it, such as dirt and grass in the suburbs and along the river. You should also pay attention to prevent the fire source from jumping in time and causing major fire accidents, which is not worth the candle. No matter what you do, you should pay attention to putting out the fire to prevent the fire from happening.
