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, to suggest the implementation, and to transfer the technology of l ight-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 with M3 ratio (proper ratio), set up the steels, and injecting the aerated foams. From the testing results followed the TIS.2226-2548 and TIS.878-2537, 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. the developing product can apply to register the petty patent.
