Abstract
In this paper, results of tests on the strength and' deformation of lightweight fibre reinforced ferrocement subjected to uniaxial tension are presented. Three values of direct sand replacement by foamed blast furnace slag, four values of fibre volume fraction in terms of the number of wire mesh layers per specimen have been used. Different combinations of these parameters resulted in 48 different specimens. Streamlined specimens were tested using friction grips working on lazytongs principle. An attempt is made to predict strength at first crack, strain at first crack, ultimate strenght and strain at 90% of ultimate stress. A trilinear plot is proposed to represent the stress-strain characteristics of light-weight fibre reinforced ferrocement in tension. Also, the influence of the different constituent materials on the stress-strain characteristics is reported.
