In the Case Study article above, the dormitory building is constructed of brick and precast concrete. This article describes precast concrete and its benefits to the construction process.
Precast concrete is a construction material created by pouring concrete into a preshaped mold or form. The concrete is then left to cure in an appropriate environment. Once cured, the mold is removed and reused.
Different Construction Method from Cast-in-Place Concrete
To produce precast concrete structures, the molds are first prepared in the desired shape. Once the molds are fixed, the concrete mix is poured into them. After pouring, the mixture is left to cure. Factors like temperature and humidity are precisely controlled during the curing process. Once the precast is cured, the molds are removed, and the finished product is shipped to the job site. Since the molds can be shaped in any form, precast concrete can come in various shapes and sizes.
Several Components Make Up a Precast Structure
Several different components go into making a precast concrete structure. These materials include cement, water, supplementary cementitious material, and an aggregate of some kind.
Multiple Benefits of Precast Concrete
Benefits of precast compared to cast-in-place concrete include construction speed, core strength, the ability to control the casting environment, quality control, and cost savings.
