Development of Light-weight Precast Concrete Wall Panel Product with Adding High Density Foam Sheet

Abstract

This research aim to study the production process, proper ratio, physical and mechanical properties, thermal conductivity, and implementation of light-weight precast concrete wall panel product with an added high density foam sheet. The light-weight precast concrete wall panel product was produced by covering the foam sheet with steel, pouring the mortar (M3 ratio which was proper ratio) and curing the light-weight precast concrete wall panel product. According to the TIS.2226 - 2548 and TIS.878 - 2537, the results revealed that the general characteristics of the light-weight precast concrete wall panel product were perfect square shape. The properties of the light-weight precast concrete wall panel product included 17.81 MPa of compressive strength, no bending was observed when installed in common behavior, 11.38% of water absorption, passes in type 1 hardness and impact tests, 956.03 kg/m³ of density, 9.18 MPa of bending strength, and 0.170 watt/m.K of thermal insulation. This light-weight precast concrete wall panel product can be used as a thermal  insulation wall within a building.
