The Impact of Density and Porosity on Thermal Properties of Kernelrazzo Concrete Floor Finish

Abstract

Understanding the impact of density and porosity on the thermal characteristics of kernelrazzo concrete floor finish was the study's main goal. Kernelrazzo is a combination of palm kernel shell, marble chippings in place of terrazzo, quarry dust, cement, palm oil fuel ash and water. In this study, it was determined which factors normally have the biggest influence on the thermal development of kernelrazzo concrete by conducting a scan of the literature and specifications. In this study, experiments in the laboratory were carried out at USM's HBP Concrete Lab. The components were mechanically combined in a concrete mixer with the calculated water using the Department of Environment (DoE) method. Concrete mix design for M20 grade is included in the scope of laboratory investigations. Ordinary Portland Cement (OPC), palm oil fuel ash (POFA) was used as an added pozzolana element, and quarry dust, aggregates made from palm kernel shell (PKS), and marble chippings were utilized to create the mixture. By examining kernelrazzo concrete cube samples after proper curing, the study involved estimating density, specific heat, thermal diffusivity, and thermal conductivity. Density is important to control the material's thermal characteristics of kernelrazzo concrete. Lower-density kernelrazzo concrete is a sign of more porosity. In lower-density kernelrazzo concrete, specific heat capacity, thermal diffusivity, and thermal conductivity are all decreased. There is strong relationship between thermal properties, temperature, density, water, and porosity.

Influence of Palm Kernel Shell on Mechanical Properties on The Achievement of Kernelrazzo Concrete Floor Finish Production

“…In order to create kernelrazzo, palm kernel shell (PKS) can be utilized as a partial replacement for marble chippings (MC) in terrazzo floor finish, either entirely or to some amount [21][22][23][24]. One of the ideas at the forefront of several proposals focusing on reducing the costs of conventional building materials has been the sourcing, development, and use of alternative, non-conventional local construction materials, including the potential use of some indigenous building materials.…”

“…The unit weight of the palm kernel shell aggregate is 500-600 kg/m 3 , which is almost 60% less than the weight of traditional crushed stone aggregates [21,32,33]. The creation and application of local building materials that are alternative and non-traditional, including the potential use of some agricultural wastes and by-products as building materials, has been one of the proposals that has been at the forefront.…”
