Properties of Foamed Lightweight Material Produced Using Blended Cement-Limestone Powder

Article Preview

Abstract:

The present study aims to investigate the engineering properties of foam lightweight material (FLM) that was produced using a mixture of ordinary Portland cement (OPC) and limestone powder (LP). The FLM samples were prepared with various proportions of LP (10%, 20%, and 30%) and different percentages of foam (9%, 12%, and 15%). Properties of the FLM were evaluated through the values of compressive strength, dry density, porosity, and thermal conductivity. Test results show that the foam contents affected all properties of the FLM significantly, whereas LP contents showed the insignificant effect to the FLM properties. Furthermore, the results of the present study showed a close correlation between porosity and other properties of the FLM as higher porosity resulted in lower density and thus lower thermal conductivity and mechanical strength.
