The Effect of the Type of Reinforcement on the Mechanical Parameters of Concrete and on its Explosion Resistance

Abstract:

The paper summarizes the up to now results of the development of special concrete intended for the explosion resistance applications, the emphasis is put also on minimal secondary fragments formation at the explosion. The fine-grained concrete matrix has been reinforced by various types of dispersed fibers (metallic, mineral and polymer) of different sizes and by their combination, while the same volume content of fibres has been kept. The concrete prism samples have been subjected to the determination of mechanical parameters (compressive and flexural strength, modulus of elasticity). The concrete test elements of the same sizes as commercial products have been made and their explosion resistance was tested. The material characteristics and explosion test data have been used for modeling the adequate wall thickness of the concrete element which should resist the explosion defined by type, size, weight and placement of the blast. In the next step the test elements has been reinforced by additional outer layer of non-metallic tissue and subjected to explosion tests.
