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.

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. Application of hollow block: These blocks can be used in load-bearing structures, low-rise residential, office buildings, bungalows, shelter units … The surface of Disadvantages.

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.

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.
