การทำโครงงานครั้งนี้มีวัตถุประสงค์

This project aims to produce low-cost cement used in construction materials, some by hand or with a very natural is a clay and shells and mixed with the cement standard by technical and scientific processes such as evaporation of weights and measures. Increasing the surface area exposed by grinding them into powder in detail. The use of the binding reaction of gravity of world cement product manufacturing. quality control is by weighing the mass of curing period of impact resistance, resistance to acid-base solution and stream water. Find properties close to the cement standard, but there are certain restrictions in the required weight or where there is a stream of water flowing all the time. In addition, when charged production cost. Cement mixed with clay and shells are also cheaper than the standard 3 percent, cement baht.

The objective of this project. To produce low-cost cement for the construction of some kind. The waste a lot of natural clay and shells. And mixed with cement standards By providing technical and scientific processes such as evaporation, the measure increases the surface area exposed by grinding to a fine powder. Using a binder Chemical reaction Earth's gravity Production of cement products A quality check by weighing the mass. Setting time Shock Resistant Resistant to acid - base and currents. Find a treasure close to the cement standards. However, there are some limitations in its use to gain more weight. Or the water flow at all times. In addition, when the cost of production. Cement mixed with clay and shells still cheaper than standard cement THB 3 per cent.

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 stone and mixed with cement standard.Such as weighing and measuring evaporation, to increase 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 the weighing mass.Endurance impact resistant and acid - base current. Found a treasure close to the cement standard. But there are some limitations in applications to the weight. The current flowing through or over time.Cement mixed with clay and stone also cheaper than cement standard 3 percent).
