Effect of Geopolymer Concrete Infill on Profiled Steel Sheeting Half Dry Board (PSSHDB) Floor System Subjected to Bending Moment

Abstract:

Profiled Steel sheeting Dry Board (PSSDB) system is a lightweight composite structural system consisting of profiled steel sheeting, mechanically connected to a dry board using self-drilling and self-tapping screw. The objective of this study is to investigate the effect of geopolymer concrete infill in PSSDB system with half board (PSSHDB), focus on its deflection serviceability limit at mid-span region. Geopolymer concrete was chosen to be as infill in the PSSDB floor system due to its high compressive strength as compared to normal concrete and its potential as an alternative concrete since it does not utilize Ordinary Portland Cement (OPC). This study used a modified PSSHDB panel using a half-sized dry board. In achieving this objective, forecasting the behavior of the system in laboratory experiments will be taken into account as the research approach. Experimental results found that with the use of geopolymer concrete infill, the mid-span deflection on the PSSHDB floor system can be reduced to 41% as compared to the use of normal concrete infill. This indicates an increase in the stiffness of this system due to the effect of infill geopolymer concrete.
