WHAT IS PRECAST CONCRETE
Precast concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and lifted into place. In contrast, standard concrete is poured into site-specific forms and cured on site
By producing precast concrete in a controlled environment (typically referred to as a precast plant), the precast concrete is afforded the opportunity to properly cure and be closely monitored by plant employees. Utilizing a Precast Concrete system offers many potential advantages over site casting of concrete. The production process for Precast Concrete is performed on ground level, which helps with safety throughout a project. There is a greater control of the quality of materials and workmanship in a precast plant rather than on a construction site. Financially, the forms used in a precast plant may be reused hundreds to thousands of times before they have to be replaced, which allows cost of formwork per unit to be lower than for site-cast production
Precast Wall Technology
Precast wall usually refers to concrete walls that are first cast with cement forming and then installed later. These precast concrete walls have been around for several decades and have seen several revisions and changes to become what is used today. Original concrete walls were simply precast concrete columns, spaced four to eight feet apart with wire or paneling strung between each column.
A Brief History on Precast Wall
Technological advancements made 20 to 30 years ago started to change the way precast wall was manufactured. The first precast walls were cast while lying horizontally on the ground. As innovations were made, smaller precast wall systems could be cast vertically and have texture on both sides unlike one-sided finished products from horizontal systems.
