Is your bike the Wicked Witch of the West? A little water and "I'm melting!" Your bike is going to be perfectly fine. I went into a pit of freshly poured concrete that was waist deep, the construction people got me out, hosed me and the bike down and the bike was none the worst for wear.
I did learn something, wet concrete is exactly the same color as dry concrete.
