Abstract
In this paper eight successive experimental blast tests with an increasing TNT equivalent charge weights ranging from 0.56 kg to 17.78 kg were conducted on unreinforced, ferrocemented overlay masonry and confined masonry walls. The pressure-time history caused by the blast was recorded by pressure sensors installed on the test specimen. The resulting damage pattern was observed during each test. Weak zones in the three systems of masonry were identified. Scaled distances for different damage levels in the three masonry systems were experimentally obtained. The results provide a basis for determining the response of each masonry system against blast loading. Consequently, efficiency of ferrocemented overlay masonry and confined masonry was found established in mitigation against blast loads.
