The water doesn't evaporate, it is consumed in a chemical reaction. It's a fundamentally different process, not an arbitrary linguistic rule. In fact, you have to be careful that the concrete doesn't dry out during the curing process.
Also, cured concrete isn't necessarily dry. For structures like bridge piers, concrete can, and often does, cure underwater.
That said, if x3n0ph3n3's intent was to enlighten rather than score points, he could have explained this more clearly.
- StavrosK 11y agoDoes the reaction not require oxygen? I was wondering what happened to concrete underwater.
- Turing_Machine 11y agoNope. Some plasters, mortars, cements, and similar substances require exposure to air (actually it's usually carbon dioxide they need rather than oxygen) but others, including modern Portland cement, do not. Classic Roman concrete would also set under water.
