Industrial preparation of cement

Sep 02, 2020 Concrete surfaces are prepared prior to resurfacing concrete to look like plain concrete again or to be upgraded to a decorative finish. Today polymers can be applied as thin as 1/8 or up to 3/4 thick and stamped, producing a surface that looks just like a normal stamped concrete surface.

    The manufacture of concrete is fairly simple. First, the cement (usually Portland cement) is prepared. Next, the other ingredients—aggregates (such as sand or gravel), admixtures (chemical additives), any necessary fibers, and water—are mixed together with the cement to form concrete. The concrete is then shipped to the work site and placed
