On mtexture.com you can search a database with architectural materials, concrete, brick, wood, carpets, resin you name it. Search for colors, surface appearance or just for materials, like for concrete on this image.
The great part is, that all materials are downloadable for free and they are even tiled, so you can easily use them as textures for architectural renderings! The site is published by the architecture office h2c in Zurich.
