Main materials required for pipe gallery
Thread Content
Recently, at a meeting on the civil construction of a pipe gallery, it was mentioned that the main materials required are cement, steel bars, yellow sand, and steel sections. There is also a word (people and workers next to the stone, people on top and workers below). I don’t know what the word is and what material it is? Thanks
Is it concrete? That's the scientific name of concrete, it seems like this.
""Concrete" refers to the three words "concrete".
“"Concrete" tong means concrete, including refractory concrete (ie refractory concrete), thermal insulation concrete (ie thermal insulation concrete), acid-resistant concrete, fire-resistant concrete and many more.
Thanks! study * Yeah, I've seen it in the drawings too.
