Precast concrete is a construction material that is manufactured by casting concrete in a reusable form. The cast is then cured and transported to the construction site. Unlike standard concrete which is cured in the construction site, precast concrete is manufactured in specially equipped manufacturing plants and then transported to the construction site, ready to be installed. The precast concrete are manufactured in plants, some of which needs to be certified by architectural associations and other government agencies. Moreover, precast concrete manufacturing activities in manufacturing plants ensures better quality as compared to standard concrete manufactured in construction sites.

Raw materials required for precast concrete manufacturing include cement, aggregates and water. Precast concrete manufacturing is carried out in controlled environmental condition and hence it is independent of adverse weather conditions. Owing to this the manufacturing process of precast concrete is unhindered and hence the supply fluctuation is generally nonexistent. Precast concrete materials can be reused for several times before they needs to be replace.
