Analysis on Mechanical Properties of Recycled Large Aggregate-Self-compacting Mortar Concrete
In order to study the effects of recycled aggregate particle size,recycled aggregate strength and self-compacting mortar strength on its mechanical properties ABAQUS is used to simulate the uniaxial compressive test of recycled large aggregate-self-compacting mortar rockfilled concrete specimens,compare the test values and simulation values,and verify the rationality of the model.The results show that the two-dimensional regular pentagonal random aggregate model is used for uniaxial compression analysis.The particle size of recycled aggregate,the strength of recycled aggregate preparation and the strength of self-compacting mortar preparation are used as variables to study the influence of the above three factors on the axial compressive strength of recycled large aggregate-self-compacting mortar concrete.The simulation results are in good agreement with the experimental results,which further verifies the rationality of the mesoscopic model.
