Concrete has been around for thousands of years. The Romans were the first to use it on a grand scale. The Colosseum in Rome was built primarily with concrete, Yet we are still finding new applications for concrete in architectural design.
Sometimes people use the words concrete and cement interchangeably. But concrete and cement are not at all the same material. Concrete is basically made of three things, aggregate (sand, gravel or rock), water and…cement. Cement, the most prevalent being Portland cement, is the crucial ingredient that binds the aggregate into hardened concrete. And concrete actually gets harder and harder over the years. Portland cement is not a brand name, but a type of cement.
For that industrial look there are all types of exposed concrete treatments. I came across this project on Houzz the other day. http://www.houzz.com/photos/16707662/Prymont-Apartment-contemporary-living-room-sydney
And if you’re not into grey try some colored concrete. The colors and textures are amazing —> http://www.houzz.com/photos/2235374/Backyard-Patio-contemporary-patio-seattle
It doesn’t stop at structural elements either. There’s a whole host of furniture that incorporates concrete: dining tables, chairs, sinks, seating, even pendant lighting.
I hope I’ve made this concrete enough for you, and firmed it up, plus made it solid.
