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...

description 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 aggregate. This study presents the viability of RA with different ratios of 25, 50, 75 and 100% in Recycled Aggregate Concrete Sandwich Panel, RACSP. The structural behavior of the RACSP was investigated experimentally and analysed in the context of transverse load capacity, load�deflection profile, load strain curves, cracking patterns and mode of failure. LVDT was used to measure the mid-span deflection and the slip between both wythes of RACSP. Strain gauges were used to measure the strain on the surface of concrete wythes. It was found that the strength of the panels with RA decreased nonlinearly with the increase of percentage replacement of RA in concrete.
