Finite Element Analysis of Compressive Strength of Recycled Coarse Aggregate-Filled Concrete

In order to study prism compressive strength of recycled coarse aggregates-filled concrete, recycled coarse aggregates of particle size for 40-80mm were made from abandoned brick and concrete blocks. 4 groups of recycled coarse aggregates-filled concrete prism objects were made, and the compressive strength of the specimens were done. Using the finite element analytical software(ANSYS) , the stress nephogram and fractured condition of recycled coarse aggregate-filled concrete were obtained after the establishment of the geometric model, calculational model and mechanical model. The results showed that numerical simulation results were good agree with the actual experimental results.
