Precast Construction

The traditional cast-in-place concrete for the erecting frames demanded ever more significant labor on the construction site (refer to Fig. 1.3.2, and Fig. 9.1.1 of Chapter 9). The weight of the precast concrete members can be significantly heavier for structures designed to carry heavy loads.

10 Benefits of Precast Concrete

For heavy projects with immense loads, precast plants can use prestressed concrete to improve the overall strength and load-bearing capacities of the resulting precast. Using prestressed concrete for large construction projects helps minimize the overall cross-section size of load-bearing members, thus reducing construction costs.
