Recently, the technology of thermal imaging has found success in yet another application: evaluation of concrete structures. Infrared cameras detect thermal radiation, or heat, and translate the radiation into a thermal image that the human eye can see. We can then understand temperature differences by the colors depicted in the image.

Shrinkage of concrete occurs during the curing and hydration of concrete as moisture loss occurs. When this occurs, concrete naturally shrinks down. In today's world of fast track construction, it has become normal to install tile and stone over newer concrete slabs that may not have experienced all the shrinkage that it will undergo.

What is Decomposed Granite. Decomposed granite, is not actually granite that has decomposed. In fact, it is a result of the mere breaking of a granite stone. When the granite breaks down, it forms a lot of tiny pieces. These tiny pieces develop a reddish tinge and have a very gravel like appearance. Right from the look to even the feel and texture.
