Troubleshooting and Durability

Understand what “concrete cancer” can mean, how deterioration is assessed, why symptoms are not diagnoses, and how durable repair and prevention are planned.

Learn why concrete tiles and slabs warp or curl, how moisture and temperature gradients act, and which design, production, and storage controls help.

A practical framework for concrete durability: classify exposure, control transport, select materials, execute well, and verify performance.

How mixture, access, placement, consolidation, reinforcement spacing, and formwork interact—and why assessment must come before repair selection.

A system-based method to distinguish low initial slump from slump loss, identify interacting drivers, and control workability without uncontrolled water addition.
