Pullout Test of Concrete Blocks Strengthened with Near CONCRETE MICROSTRUCTURE POROSITY AND PERMEABILITY

Test setup The concrete blocks were tested in MTS BALDWIN machine as shown in Figure 5 The applied load was reacted by means of four steel threaded bars inserted into holes made in the block passing through two steel plates over and under the block and the bar was pulled up as shown in Figure 2 8 Instrumentation Two LVDTs were used to measure the free end and the loaded end slip of the SHRP C 628 Concrete Microstructure Porosity and Permeability DM Roy PW Brown D Ski BE Scheetz W May Materials Research Laboratory The Pennsylvania State University
