Cement-produced concrete usually corrodes and is severely damaged after a period of use in sewer networks due to the large amount of salts and chemicals in the sewer water. Therefore, researchers have developed a new method for producing concrete that prevents it from being damaged.

In this concrete, steel slag in the form of aggregate has been used and some types of construction and road debris have also been used to increase the strength of concrete. Other materials in this cement that are resistant to corrosion and penetration of acids and fats, such as nano-silica, slag and hydrated lime can be mentioned.

Laboratory studies on this new concrete show that its resistance to corrosion reaches 96%, and by changing its composition, we can expect this resistance to increase by nearly 100%.
