Precast Concrete Construction
With over 6 billion cubic meters of concrete produced every year, it remains one of the most popular man-made construction material in the world. For thousands of years, builders have depended on the versatility and strength of concrete, to create structures that have withstood the test of time. Its durability, superior strength, as well as overall structural integrity, make precast concrete the go-to construction material in countless applications. According to the Army Corps of Engineers, precast concrete structures have a useful life of around 80 years. Additionally, the structures continue to function properly, long after the useful life has elapsed. Precast concrete is commonly used in mid and low-rise apartment buildings, nursing homes, hotels and motels. Concrete provides superior sound control and fire resistance, for the individual units while reducing fire insurance rates.
disadvantages of hollow core planks
This kind of slab has a more thickness 0. Low Capacity: As it is mentioned it is a small machine and it can only produce between pieces of hollow blocks manual brick laying machine and pieces of hollow concrete blocks full-automatic brick laying machine in an eight-hour shift. Rib and Block slabs that last a lifetime. Disadvantages of hollow block: Hollow blocks has poor bearing capacity because the total mass of wall decoration materials is reduced, the load-bearing capacity is also reduced. The main requirements are as follows.
Price CHF The aim of this state-of-art report is to present current practices for use of precast and prestressed concrete in countries in seismic regions, to recommend good practice, and to discuss current developments. The report has been drafted by 30 contributors from nine different countries. This state-of-art report covers: state of the practice in various countries; advantages and disadvantages of incorporating precast reinforced and prestressed concrete in construction; lessons learned from previous earthquakes; construction concepts; design approaches; primary lateral load resisting systems precast and prestressed concrete frame systems and structural walls including dual systems diaphragms of precast and prestressed concrete floor units; modelling and analytical methods; gravity load resisting systems; foundations; and miscellaneous elements shells, folded plates, stairs and architectural cladding panels. Design equations are reported where necessary, but the emphasis is on principles. Ordinary cast-in-place reinforced concrete is not considered in this report.
Prestressed Concrete- Advantages and Disadvantages
The concrete of superior quality is produced as it is possible to have better technical control on the production of concrete in factory. The labour required in the manufacturing process of the precast units can easily be trained. The moulds employed for preparing the precast units are of steel with exact dimension in all directions.

Precast Concrete vs. Site Cast Concrete
The construction industry in Ghana is becoming efficient in the area of cost and achieving advance technologies. The effective management of cost enables clients, developers, and facilitators to achieve value for money. Concrete is a major component in every construction project. The use of precast concrete technology has been embraced by the construction industry in Ghana. This study seeks to analyze cost estimating of the structural frame column and slab by considering cast-in-place and precast concrete slabs and columns, respectively.
Precast concrete, a highly efficient, practical method of concrete construction makes beautiful buildings possible at a cost that rivals even the most utilitarian industrial building. Precast concrete offers an efficient delivery model for your project; allowing building construction to proceed while the design is developed. Precast concrete can take nearly any shape or size, be manufactured in virtually any color and comes in a wide variety of finishes. With precast, you are limited only by your imagination. Precast concrete products are manufactured off-site, under roof and are delivered ready to install when needed.
Saves Construction Time: Precast Concrete construction saves time, the risk of project delay is also less. · Quality Assurance · Usage of Prestressed Concrete.
