Using container foam waste to produce light-weight precast concrete wall panel

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 light-weight precast concrete wall panel products mixed with container foam wastes. Design the ratios of Portland cement type1: coarse sand: lime stone: water equal to 1: 2: 4: 0.7 by weight and adding the container foam wastes equal to 0, 0.025, 0.050, 0.075 and 0.1 by weight. Casting the light-weight precast concrete wall panel products by pouring the concrete into the mold which installed the steels. Test the properties follow TIS.2226-2548 and TIS.878-2537. From the results, the proper ratio of adding container foam wastes was 0.075 by weight which had perfect general characteristic, 16.48 MPa of compressive strength, no bending when installed in common behavior, 8.86% of water absorption, passed type1 of hardness test, passed type 2 of impact test, 2,014.54 kg/m3 of density, 4.30 MPa of bending strength, and 0.228 watt/m.K of thermal insulation. This light-weight precast concrete wall panel product can use as the thermal insulation wall in building. Moreover, the developing product can apply to register the petty patent.
