Structural behaviour of precast concrete sandwich panel using recycled aggregate concrete under transverse load

Previous studies have been focusing on finding alternative materials in a composite building system in order to provide a strong, environmental friendly, low cost material to be used in the construction industry. In this research, recycle aggregate, RA, has been used instead of natural aggrega...
