EFFECT OF INDUSTRIAL WASTE-STEEL SLAG IN IMPACT BEHAVIOUR OF FERROCEMENT PANELS

J. Sridhar and R. Malathy

Abstract

The need to recycle and fully utilise co-products in manufacturing processes is required to conserve our finite natural resources. Technical evaluation supported by field experience has shown that co-products such as steel slag have many applications, properties suitable to replace or supplement and improve traditional materials used. The main objective of this investigation is to study the impact behaviour of ferrocement panels with galvanised square weld mesh and chicken mesh under simply supported condition and sand bed condition with partial replacement of fine aggregate by steel slag in mortar matrix under impact load. The variables considered in this study are volume fraction of mesh, steel slag content from 0% to 50% by weight of fine aggregate and support conditions. From the study, maximum energy absorption was obtained for ferrocement panels with volume fraction 2.35% under sand bed condition. The use of steel slag as an alternate to natural aggregates for mortar increases the impact strength. Furthermore, by solidification in the cement matrix, the pollution of heavy metals into soil and groundwater can be reduced significantly.
