Precast concrete

PRECAST CONCRETEPrecast concreteis a construction product produced by casting concrete in a reusablemoldor "form" which is then cured in a controlled environment, transported to the construction site and lifted into place. In contrast,standard concreteis poured into site-specific forms and cured on site.

There are many different types of precast concrete, forming systems for architectural applications, differing in size, function, and cost. Precast architectural panels are also used tocladall or part of a buildingfacadefree-standing walls used for landscaping,soundproofing, and security walls, and some can be Prestressed concretestructural elements. Storm water drainage, water and sewage pipes, and tunnels make use of precast concrete units.Reference: Kaptim Private Limited

Advantages of using precast materials Use of precast materials reduces construction time. it is cost efficient when used in bulk and makes over all construction efficient. Disadvantages of precast materialThere is not much choice in pattern and sizes.As material is precast, there is no control of the consumer over the quality of the product.A few percentage of material gets damaged during transportation.
