In fact, cement explosion has become a common occurrence. 202 1, 65438+ Nanning, Guangxi, monitoring shows that people are sitting around to keep warm, and the cement suddenly explodes, sparking, and everyone rushes away.
202 1 May1Day, Yangjiang, Guangdong, everyone barbecued on the concrete floor. While eating with relish, I didn't expect that the cement floor exploded after heating for three hours. The ground exploded more than one meter high, and the people next to it reacted quickly. Fortunately, no one was injured before the explosion.
202 1 February 21day, when a man was cooking grilled fish on the concrete floor in front of his home in Zunyi, Guizhou, an explosion suddenly occurred, and the fire rushed to a height of more than two meters. Fortunately, the man escaped in time and did not cause more harm.
There are countless similar examples, but it still can't stop us from making a fire to cook. I didn't know there was life hidden in cement!
Will cause an explosion.
It will cause a physical explosion of the cement board. Physical explosion is the destructive effect caused by the rapid expansion of objects, because cement is a poor conductor of heat, and it will explode if it is locally expanded by local heating. There is water vapor under the whole cement floor, which will condense when heated. The result will be cracking, which is called explosion.
Speaking of which, I think I had a barbecue on the concrete floor once. I'm lucky that I didn't have an accident on the braised dishes. I can't help laughing at myself. It's really "delicious to explode" covering your face ~
Therefore, if a fire is made directly on the thin concrete floor to keep warm, such a physical explosion will occur when the concrete floor burns for a long time. Although it didn't happen to us, it was enough to arouse our extensive understanding.
At the same time, we should pay attention to such a small detail as fire. Do not fire directly on the concrete floor or hard rock. If you want to bake, add soil, ash, sand or put some bricks to support the barbecue oven before burning, which can also prevent the cement floor from being heated.
Some people will say, "Why don't I just pour some water on the concrete floor?" Young man, you think too simply! Whether it is dry cement floor or wet cement floor, cooking on cement floor will explode.
Besides. Nowadays, stone and slate barbecues are also favored by neighbors. If you don't choose the right stone for heat transfer, it is easy to cause an explosion!
When you make a fire and cook outdoors, you still need to choose a suitable place to make a fire. There should be no shrubs or too many trees, and there should be no flammable items around the downdraft. Avoid caves, rooms and other closed places to avoid carbon monoxide poisoning.
Burning a fire in the suburbs will inevitably encounter flammable gathering places such as lush vegetation and leaves accumulation, so at least 10 square meter should be cleared in the barbecue site as a fire area.
When making a fire in the countryside, it is easy to have unexpected small fires, so a small fire extinguisher is needed to help. It is best to carry a fire extinguisher when traveling at ordinary times. If you don't take it, you can also prepare water in containers such as buckets and put it next to the oven just in case.
For foodies who like to barbecue themselves, please remember the common sense of cooking on the concrete floor to avoid the party from "surprise" to "scare". Let's share it here. Goodbye.
