    Abstract

    This paper presents an experimental study on fibre cement composite board (CCB) reinforced by Kraft and Blast Furnace Slag Fibres (BFSF) powder. Three different types of BFSF were used with Kraft pulp fibres extracted from waste cardboard. Three types of slag fibres including SLL (Slag fibre, long length), SLW (slag fibre, white colour) and SLY (slag fibre, yellow colour) in the range of 1-3% were used in this research. This investigation provides an important insight into the study of the effect of blast furnace slag powder on the property of CCB reinforced by cellulose fibres; as no previous literatures has investigated the use of BFS fibres. The results show that SLL does not have enough consistency with Kraft pulp fibre and degrades the flexural properties of cement board over time. The results of modulus of rupture (MOR) for 7 to 28 days dropped from 11 to 7.5 MPa, respectively. On the other hand, SLW and SLY are much more compatible with hydrated cement products and Kraft pulp fibre giving MOR values of up to 17.5 MPa at 28 days.
