Experimental Investigation on Ferrocement Slab Using Steel Fibres and Different Sands

Abstract

Ferrocement is defined as wire mesh reinforcement impregnated with mortar to produce elements of small thickness. An experimental study has been carried out to study the effect of different compositions of cement mortar using 10% fly ash and different percentage of 6–8% silica fumes with two types of sands such as Badarpur sand and river sand and show the effect of load versus deflection curve and flexural strength of ferrocement panels. Ratio of cement and sand adopted is 1:1.5 by weight of cement. Slab specimen size is 400400 mm thickness and height is 40 mm which are reinforced with square mesh with opening size of 10 mm. Panels are casted with mortar and different percentage of water cement ratio. Test result shows that panels with modified mortar containing fly ash and 8% silica fumes exhibits greater flexural strength and less deflection as that compared with panels of other mixes. The increment in flexural strength is 7.92% of ferrocement panels containing Badarpur sand using fly ash and 8% silica fume. The increase in strength in case of Yamuna sand as same phenomenon is 10.16%.
