| Summary: | Fine Grained Mortar (FGM) offers a new innovative technology binder system to strengthen or repair concrete structures. The innovative technique is achieved by using a small maximum grain size of 1 mm for the mortars. Therefore, less than 2 mm of mortar thickness would be fitted between the strengthened layers. FGM also has high binder contents, by adopting different pozzolanic additives and high performance of plasticizers. Recently, the utilisation of supplementary of cementing materials such as Fly Ash (FA) and Rice Husk Ash (RHA) has a become an important in concrete industry. It has demonstrated significant influence in improving the strength of mortar. Most of the previous studies have focused on the FA to be replaced in the FGM. There is still lacking of research of using other pozzolanas in making FGM. This paper presents an overview on the use of FA and RHA as partial replacement of cement in mortar and FGM as well as future research that will be conducted by the authors. © (2014) Trans Tech Publications, Switzerland.
