This document discusses shrinkage compensating concrete and its advantages for use in underground concrete structures and tunnels. Shrinkage compensating concrete reduces cracking caused by drying shrinkage through controlled expansion during curing. It has lower permeability and higher durability than ordinary Portland cement concrete. Case studies demonstrate that shrinkage compensating concrete effectively eliminates cracking in parking structures, wastewater infrastructure, and monolithic roof placements for over 50 years. The document concludes shrinkage compensating concrete is well-suited for tunnels due to its ability to form large leak-proof placements with minimal cracking.

This document discusses shrinkage compensating concrete and its advantages for underground concrete structures. Shrinkage compensating concrete reduces cracking through controlled expansion during curing. It has lower permeability and higher durability than ordinary Portland cement concrete. The document provides examples of underground projects that have used shrinkage compensating concrete successfully for decades. It also compares the hydration and properties of shrinkage compensating concrete to ordinary Portland cement concrete.
