Effect of Graphene Oxide on the Damping Capability of Recycled Mortar

The use of recycled aggregate as replacement of natural aggregate has increased in recent years in order to reduce the high consumption of natural resources in construction industry. This paper presents an experimental investigation on the effect of graphene oxide (GO) on the damping capability of recycled mortar. The effect of GO on damping capability was examined by using dynamic mechanical analyzer (DMA), It is showed that the recycled mortar with GO has a better damping capability than the recycled mortar without GO. Microstructural analysis of the recycled mortar with GO showed to have much denser and better crystallization of hydration products.
