An Antiperthite is an intergrowth arising due to exsolution where potassic or NaAlSi3O8 and orthoclase (Or) or KAlSi3O8 form a complete solid solution series . The carbonate cement of the Upper part of the Kongdian formation contains δ 13 C . The detrital grains of perthite, microline and orthoclase usually indicate a. Concrete is considered a composite material that is being composed of aggregate and then being bonded along with fluid cement that hardens.
Precast concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment.
