purrrpetrator Posted November 1, 2017 #126 Share Posted November 1, 2017 7 hours ago, acute said: How does concrete set underwater? The kind of cement that sets underwater uses silicates and various oxides (primarily calcium, aluminum and iron oxides). The basic chemical process that is occurring is hydration, whereby the mixture of oxides and silicates incorporates several water molecules directly into the crystal lattice. The fact that the setting process both uses water, and also produces a structure that is insoluble and robust to attack by water, is what makes underwater setting of hydraulic cement possible. How would one know, unless they asked? 4 Top Link to comment Share on other sites More sharing options...

That's actually very interesting, thank you. It uses water to set! Link to comment Share on other sites More sharing options...
