With the system is a system with precast parts design, manufacture and quality control. The use of materials in the production process quality control. The set or assembly is a structure has good standard under control conditions.However, in terms of material selection in making precast parts. It is made of reinforced concrete with strength according to the strength of the structure.Because the reinforced concrete has the very well. The properties of concrete with high water opacity The cutoff means water or moisture can not seep through easily.Made of concrete, can store water). Another feature of concrete is able to resist fire or fire resistance is no less than two hours, and non-flammable. The design criteria for concrete wall with thickness not less than.Cm a fire resistant wall, observed from a ladder by buildings. Be made of reinforced concrete. From the property with high opacity (firmness), concrete is much keep noise well.Of course the fullness or density compared to the masonry wall building precast has thermal conductivity than the air of the room of the wall precast temperature is higher when there is no sun wallLose one.

.And it came to pass, when the concrete parts connected together in a manner. It is an important part of the system of precast. In general, in the structural design of precast system must consider is the point (Joint) joint design (Connection Joint).Such as, tension, shear, compression, later such joints must be beautiful can prevent water or moisture (rain) due to our house from located in hot condition Humid conditions hot and rainy.Seepage of water or moisture happens affects the walls, floor, ceiling or other in the home or building. So it is a weakness of the system of joint precast another point. To be considered and verify.?Because the joint precast if designed to use joist type silicone (like the windows, doors, made from aluminum). I usually have a deterioration due to longevity and durability with UV from sunlight.(life 5-10 years). Depending on the quality and type of silicone used. Interface for use with a solder joint mortar (cement, sand, water) or material of the sleep of Gera (Non initiative -shrink grout).(shrinkage) of cement, sand, or motorcycle parts guitar with a concrete precast Because the concrete shrinkage than cement, sand, or mor guitar very much. The cases used to sleep as it has found the problem less armor using lime sand in general.The strength or strength of sleep as armor to there is no less than concrete.
