ADVANTAGES OF PRECAST CONCRETE OVER RCC (RIENFORCED CEMENT CONCRETE)
1. Precast concrete is COMFORTABLE
The material has intrinsic properties of thermal
inertia (allowing a more constant temperature both in cold and hot
regions) and acoustic insulation.
2. Precast concrete is SAFE
Everybody knows that concrete does not burn!
Not only is the structural stability maintained for
longer periods, but concrete construction prevents the spread of the fire from
one building to another.
It is sufficiently strong to resist impacts, blasts
and natural catastrophes like earthquakes, tornadoes and floods.
3. Precast concrete is VERSATILE
Factory production allows a wide choice of surface
finishing, colour range and special shapes. Precast concrete has
another advantage: its mouldability which entails designers to copy classical
details like keystones and capitals or match the finish of materials like
weathered stones. The precast concrete industry can source a wide range of
aggregates locally and offer a tremendous variety of colors and visual effects.
4. Precast concrete is HEALTHY
Indoor air quality is a concern for all of us.
Precast concrete is stable throughout its life and does not
need chemical treatment to protect it against rot and insect attack: this means
that there areno emissions in the internal environment.
Advanced technologies used in the precasting plants create
an improved quality product (i.e. reduced tolerances, thinner
sections, engineered solutions) compared with cast-on-site concrete.
Additionally this quality can be checked before a unit is inserted into the
structure or site work!
6. Precast concrete is DURABLE
Concrete lasts for years.
Egyptian and Chinese people used an ancient form of concrete
for buildings and structures that still exist today. Concrete is used where the
structural stability has to be maintained for long periods. Effective design
detailing helps to lengthen the life of a concrete building; precast
manufacturers can offer guidance on designing for durability.
7. Precast concrete is ECOLOGICAL
Made of natural raw materials (stones, gravels, sand,
cement), locally available almost everywhere and in an enormous
quantity, precast concrete minimizes the whole life cycle impact on the environment when
compared with other construction materials.
Precast concrete units can entirely be re-used or recycled
(almost 100% of a concrete building can be recycled, no matter how heavily
reinforced).
8. Precast concrete is FAST
The top floor of a skyscraper can be cast in the factory
when the foundations have not yet started. But the project requirements of a
modern construction prefer a just-in-time delivery! On-site construction
using precast concrete is not only faster, but also safer as secure
working platforms are quickly established.
9. Precast concrete is AFFORDABLE
Precast concrete combines the excellent quality of factory
production with a relatively inexpensive material. The costs to repair and
maintain a concrete structures are highly limited. There is therefore no
need to compromise on quality to reduce costs, simply choose the best way to
use locally available resources.
10. Precast concrete is SUSTAINABLE
Sustainable means a “3-win” situation for the
three Pillars of our society: People,Profit and the Planet. If only one of
this elements is “negative”, the solution can’t be considered sustainable!
