Abstract
.To do the project objectives For the production of cement used in construction, some low cost type. The waste material or there are a lot of nature is clay and clay. The clay engaging assembly is alumina (AI2O3).(SiO2) the shell through the heat of high lime (CaO) react with water to compounds with strength. Already mixed with cement standard. By comparing the technical and scientific process, such as weighing and measuring.Increasing the surface area exposed by grind to a fine powder the binder. Chemical reaction. The gravity of the earth, to produce cement. A quality inspection by weighing mass setting time.Resistant to acid - base and tides. Found a treasure close to the cement standard. But there are some limitations in applications to heavy or blunt force trauma also when on the production cost.3)
