Precast concrete is a construction product produced by casting in a reusable or "form" which is then cured in a controlled environment, transported to the construction site and maneuvered into place; examples include precast , and wall panels for construction. In contrast, cast-in-place concrete is poured into site-specific forms and cured on site.
