Creative development of ferrocement technology in the construction industry has enhanced dynamically due to its faster construction, lighter weight, higher strength, durability and economical advantages than the reinforced concrete structures. The use of smaller diameter closely spaced mesh layers which is uniformly distributed throughout the cross section improved the moment of resistance, deflection and ductility of the ferrocement members. To achieve the environmental friendliness and sustainability in the durable ferrocement technology, this paper aims to provide a comprehensive implication reviewed from the previous research works carried out to explore the application of industrial waste materials in the ferrocement construction. Influence of various industrial waste materials on the behaviour of both mortar and meshing reinforcement were discussed separately. The optimum level replacement, effect on the structural behaviour and the suitability in the various environmental conditions were inferred. For instance, Ground Granulated Blast furnace Slag (GGBS) could be utilized as a binder at the maximum of 50% by weight, where as the use of metakaolin in ferrocement construction is optimum at 15% by weight as further addition caused the undesirable effect on the mechanical properties due to the delay in hydration process and inefficient filler effect. Grain size modified nano industrial wastes like nano silica and nano fly ash resulted in improved mechanical and micro structural behaviour of ferrocement products due to its nano filling effect. The use of nano fly ash was found to be successful as nano binder to the maximum of 10% which is not possible in case of other costlier nano materials like nano silica, alumina, titanium oxide, etc. The major issues of corrosion and chemical attack in ferrocement mesh were easily solved by the implementation of high molar geopolymer mortar which also resulted in cleaner and greener production of ferrocement products.
