Utilisation of waste cardboard and Nano silica fume in the production of fibre cement board reinforced by glass fibres

Abstract In this research, Glass Fibres (GL), Kraft pulp Fibres (KF) and Nano Silica Fume (NSF) were used to produce Cement Composite Board (CCB). Fifteen groups of mix proportions were produced to investigate the effects of fibre content and size along with the effect of NSF on interaction, bonding and mechanical properties of CCB. Density, Water Absorption, Moisture Movement, Flexural Strength test and Scanning Electron Microscopy observations were conducted. The results showed that some mixes could meet the standard requirements and also the inclusion of GL and NSF into the mix containing KF (extracted from waste cardboard) could enhance the characteristics of CCB.
