PDF PRECAST CONCRETE CONSTRUCTION - World Housing

Precast reinforced concrete frame with cruciform and linear beam elements (Seria 106) is an example of a frame system with precast beam-column subassemblages (Kyrgyzstan, WHE Report 33). The system was developed in Kyrgyzstan in 1975. The load-bearing structure consists of a precast reinforced concrete space frame and precast floor slabs.

Advantages of Precast Concrete in Constructing Highways

The main advantages of precast concrete over cast-in-place (placement of pavement or object in-situ) are as follows: Precast pavement panels or bridge elements can be cast and cured in a controlled environment at a precast plant, providing greater control over consistency of the concrete mix, procedures of vibration and proper curing.

The history of precast concrete elements

Precast concrete elements – how it all began. Joseph Monier (1823 – 1906) was a gardener and his idea was to develop permanent planters at a low price. In 1867, he patented different products made of reinforced concrete. After his invention of reinforced concrete the next logical step was the invention of precast concrete elements because

Difference Between RCC and Prestressed Concrete

The concrete used in prestressed concrete should be well compacted. High strength concrete is used in prestressed concrete for following reasons: Use of high strength concrete results in smaller sections. High strength concrete offers high resistance in tension, shear, bond and bearing. Less loss of prestress occurs with high strength concrete.
