    What is a chemical compound,when exposed to air becomes a durable solid?

    I am trying to start with a chemical compound that hardens quickly upon exposure to air. It is meant to be unlike that of industrial superglue but more of something like quick dry cement. I have problems determining the compound to make it harden fast and durable.
