Determine the remaining compressive strength of cement base porus material using continuum damaged mechanic concept

Concrete is a very fragile material, a sudden collapse is the main feature of this cement-based material. This study will describe the results of experimental material studies when subjected to incremental uniaxial loading-unloading. At each one cycle loading phase a modulus of elasticity was measured. Test results show that loading between 0 and 0.4 fc, there is no change in the modulus elasticity value. But after passing through the stable range, the number of elastic modulus increases sharply.
