Experimental investigation on different high rich cement mortar for ferrocement application

Abstract

Abstract Nowadays the Laboratory research became assumed to enlarge high rich cementitious matrices for casting thin ferrocement laminates perfectly fitted for structural restore retrofit. The developed high rich mortar matrices contain diverse combos of silica fume and Metakaolin, and offer a great balance among flowability and rich. The matrices evolved have a 28-days compressive rich variety from 48 to 64 MPa with an equivalent float range from 129% to 138%. The different high rich mortar turned into used in generating ferrocement jackets for cylindrical stubs look at its performance of the stubs are subjected to axial stresses. The progressive excessive rich ferrocement laminates seem to provide the considerable increase and increasing in the load carrying potential, lateral and ductility. In positions of ferrocement efficiency, the stubs enveloped with the laminates containing 2 and 4 layers of welded wire meshes (WWM), presented approximately 61% and 31% increase in axial stress respectively, with a corresponding increase in axial stress of about 33% and 71% respectively. Based on the outcomes of the present research, high rich ferrocement laminates containing a particular variety of welded wire meshes may be taken into consideration as a promising material for maintenance and recovery of concrete structures, particularly when using flowable high rich mortar with WWM complying with ferrocement specifications.
