Analazing the impact behavior of porous concrete
conference paper
Porous concrete is a special type of cementitious material incorporating a high amount of meso-size air pores that makes its characteristics markedly different from normal concrete. Therefore, it is being investigated for various applications, aiming to benefit from the presence of the air voids in its structure, such as permeability, noise absorption or thermal insulation. While its performance in various fields of usage is of high interest, the behavior of porous concrete under impact loading is not as widely investigated. A research project was undertaken to design a special type of porous concrete, that fractures into small fragments when exposed to impact loading while having sufficient static strength, to be used in protective structures such as safety walls or storages for explosives. The project comprised of both experimental and numerical analyses that have been conducted to investigate the porous concrete material, especially in terms of its impact behavior, and to understand the parameters that control its performance, which are significantly different from those of normal concrete. In the currently presented study, some of the experimental methods and results from impact experiments as well as representative results from the numerical analyses have been presented.
