Study of Light-weight Precast Concrete Wall Panel Product with Aerated Foam Injection Technique as Core Wall

Abstract

The objectives of this research are to study the production, to find the proper ratio, to test the physical, mechanical properties, and thermal conductivity, and to suggest the implementation of light-weight precast concrete wall panel product with aerated foam injection technique as core wall. The light-weight precast concrete wall panel product was produced by casting the mortar panels which equal to 1:3:0.5 by weight of the Portland cement type1: fine sand: water ratio (proper ratio), set up the steels, and injecting the aerated foams. From the testing results of light-weight precast concrete wall panel product with aerated foam injection technique as core wall followed the TIS.2226 - 2548 (Precast Concrete Wall Panels) and TIS.878 - 2537 (Cement Bonded Particleboards : High Density), the general characteristic of light-weight precast concrete wall panel product was perfect. The properties of light-weight precast concrete wall panel product include 17.81 MPa of compressive strength, no bending when installed in common behavior, 11.38% of water absorption, passed in type1 of hardness and impact test, 1,110.58 kg/m3 of density, 9.18 MPa of bending strength, and 0.186 watt/m.K of thermal insulation. This light-weight precast concrete wall panel product can use as the thermal insulation wall in building.
