Mar 07, 2018There are two common methods of manufacturing cast stone: one is the dry tamp method and the other is the wet cast process. Both of these methods create a simulated natural cut stone look.The most common finish for a dry tamp cast stone is limestone or sandstone while the wet cast method is capable of providing a wider array of possible finishes.

May 09, 2012Cement manufacturing is highly energy- and emissions-intensive because of the extreme heat required to produce it. Producing a ton of cement requires 4.7 million BTU of energy, equivalent to about 400 pounds of coal, and generates nearly a ton of CO 2. Given its high emissions and critical importance to society, cement is an obvious place to
