Building material & construction lab.

In this study, it was evaluated the protective performance of the protection material for filed of the army by
impact of fragment from the explosion of 155mm artillery shell to propose the improvement items. And it was
evaluated the protection materials for structural boby such as corrugated steel plate, concrete block, prevention
paint of explosion, aluminum foam and concrete T-wall by impact of fragment of 155mm artillery shells and
explosion-induced pressure of C-4 explosive. As a result, protective performance of the existing protective material
was superior but reinforcement is necessary for secondary damage because sand is leaking. The protective
performance of new protective materials was greater than existing protective materials. And it can be used for
protective materials.
