The high-rise building is obviously made of concrete, so why does the whole building burn after a fire? foaming agent for concrete

If you are looking for high-quality products, please feel free to contact us and send an inquiry, email:

First, concrete takes in and moves warmth extra easily than dissipates warmth easily. When a fire takes place, it has the effect of sustaining burning, which amounts adding fuel to the fire. The even more it burns, the bigger it gets. Concrete may seem beautiful and strong, yet in fact, maybe much better than adobe houses. There is no thermal insulation and warmth dissipation result like adobe blocks.

On the other hand, I just damaged the surface area. If the steel-concrete framework of a high-rise building is white, there will not be a lot of smoke and fire if it burns. It is generally constructed from interior decoration products, mostly natural materials, oil, or plastic materials., as soon as fired up, the fire will come to be tough and generate a large amount of black smoke.

Second, fires in skyscrapers can melt concrete and steel bars. Oxygen supports combustion. In addition, the temperature level created by the supporting burning of other flammable items in the building is very high. After all, it is not a fire in a country home. In the 911 incident, one structure was destroyed by an aircraft. After the crash, it did not collapse at the time. Later on, the fire triggered by the influence shed and melted the text of reinforced concrete and ultimately collapsed.

On the various other hand, indoor design products, home devices and furnishings are primarily combustible. If one flooring burns for a long time, the temperature level will certainly permeate the floor and fire up the upper and reduced floorings. The flooring is high and windy, with excellent ventilation and high oxygen content. The high-temperature heat flow will develop a smoke. Power, the fire needs to be really strong.

Third, the foam plastic used for exterior wall surface insulation is the culprit. Foam plastics are generally used in Europe and the USA, so a team of professionals introduced this innovation. But they clearly should have taken into consideration that the majority of foreign structures are two- or three-story domestic structures, and fire protection demands are reduced. When a fire breaks out in the structure, it will certainly create severe repercussions. Two- and three-story structures are not mainstream in China, and also in backwoods, there are really few of them. To present modern technology, we need to take into consideration the current situation of residential building. Or else, we will certainly be finding out in Handan.

Fourth, the emphasis is not on room furniture and wood products yet on the reality that paint is made use of in all constructing designs, such as wall paint. Also high-end wall surface treatments are textiles. Repaint or textiles are inherently flammable objects. Furthermore, numerous other decoration materials have various shades. The shades are likewise made from various kinds of paint. Once they experience high temperatures, they will certainly burn also if there is no open flame.

On the various other hand, I have actually seen many people saying that the high quality of thermal insulation products is not up to par. In fact, it is not just moisture-retaining products. The country additionally has matching fire retardant requirements for timber utilized for interior decoration and furnishings of high-rise buildings, but furnishings factories and structure products factories will certainly avoid this. Common customers do not comprehend the trouble, so primarily, the wooden materials on the marketplace are non-fire retardant products, whether they are used in high-rise buildings or otherwise.

Fifth, ideas from firemens to avoid problems prior to they occur: Each flooring should be equipped with a fire hydrant. If the area is big, you can additionally gear up numerous. If a fire occurs, rapidly manage the fire to avoid the fire from spreading to various other floors. If it is a household structure, each household should be equipped with a tiny fire hydrant. Once a fire occurs in your home, the fire can be quickly controlled within your very own home. On top of that, furniture, drape decoration, and so on, must be constructed from non-combustible products. The degree of fire security automation in high-rise buildings is reasonably high. The individual in charge of fire defense in high-rise buildings is in location and responsible, and evaluations and drills are in area. Fires can be avoided by controlling combustibles, combustion-supporting materials and fire sources.

The manufacturing process of concrete is a crucial element influencing its fire resistance. Amongst them, the control of the water-cement ratio is vital. Too high or too reduced a water-cement proportion might have unfavorable effects on the fire resistance of concrete. Furthermore, the high quality and form of the rocks in concrete will likewise have an effect on its fire resistance. Using hard and regular-shaped rocks can boost the fire resistance of concrete.

Regarding the detection of fire resistance, there are lots of generally utilized approaches, such as high-temperature examination method, fire test method, thermogravimetric evaluation method, and infrared spectroscopy approach. These techniques assess the fire resistance of concrete by simulating high-temperature settings or directly observing the efficiency changes of concrete at high temperatures.
