Digital Image Model Analysis of Recycled Concrete in Meso-level
Journal Title: 河南科技大学学报（自然科学版） - Year 2017, Vol 38, Issue 2
Abstract
In order to solve the problem that the algorithm of the existed mesoscopic aggregate model of recycled concrete was complex,the modeling was idealized and the method of processing technology was traditional,the recycled concrete digital image mesoscopic model was established through the parametric programming language of software ANSYS based on real aggregate image. The digital image processing was combined with boundary vectorization technology. Digital image mesoscopic model was applied to simulate the instantaneous strain diagram of uniaxial compression cube test block. The effects of macro-mechanical response and recycled aggregate on the mechanical properties of recycled concrete were analyzed. The results show that most of the recycled concrete crack is produced,developed and formed from the large aggregate boundary. The compressive strengthes of recycled concrete within 50% mass fraction recycled large aggregate with different aggregate models are different. The simulation results of digtal image mesoscopic model agree with the test phenomena and mechanics laws,so the modeling method is reasonable and effective.
