The torsional capacity oftwo recycled aggregate concrete (RAC) beams with 100% recycled coarse aggregate(RCA) and two normal concrete beams subjected to monotonic torsion was investigatedby the finite element software ABAQUS, and the simulated results were comparedwith the experimental results. The investigation shows that recycled aggregateconcrete torsional members have good seismic behavior. The simulated resultsagree well with experimental ones. It can be reference for actual engineering.

With the increase in the use of recycled aggregate concrete (RAC), it is necessary to clearly understand its behavior and characteristics. In this paper, experimental study on compressive strength of RAC with same water/cement ratio is conducted. Firstly, influence of recycled coarse aggregate contents on cube compressive strength of RAC is studied. Secondly, experiment on time-dependent strength developing process of RAC is conducted with different solidification ages. Finally, based on above experimental investigations, empirical formula for compress strengths of RAC with different ages is presented. The result of this paper is helpful to theoretical analysis and practical engineering design of RAC structures.
