Abstract

The pullout methods LOK- TEST and CAPO-TEST for in-place compressive strength are presented with their theoretical analysis’ background and correlations from 30 major studies, made worldwide, showing robust general correlations between pullout force and strength by cylinders or cubes/ cores. The coefficient of variation of the systems are shown, reported in 1984. Practical cases using the systems are described: Case 1. In-Situ compressive strength testing of quarantined precast concrete tunnel lining segments using CAPO-TEST, UK; Case 2. Strength testing with CAPO-TEST on old bridges for further loading, Poland; Case 3. Safe and early form stripping with LOK-TEST, Canada; Case 4. Curing of the cover layer evaluated by pullout and bulk resistivity, Denmark.
