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 product with adding 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. 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 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 use as the thermal insulation wall in building. Moreover the developing product can apply to register the petty patent.

This research has objectives to study the production to find the proper size of steel wire mesh to test the properties and to study the implementation of high strength and thermal insulation cement-bonded fiberboard from coconut meal corncob fibers and steel wire mesh. The mixture ratio of cement-bonded fiberboard included Portland cement type1: sand: coconut meal fiber: corncob fiber: water: calcium chloride equal to 1: 0.2: 0.0125: 0.0375: 0.3: 0.03 by weight and 5 different sizes of steel wire mesh were reinforced. Casted by compression and sharking machine. Tested the properties follow the TIS.878-2537. From the results 1 mm of diameter and 1” of gab of steel wire mesh (? 1 mm # 1”) was the proper size to reinforce the cement-bonded fiberboard to get highest bending strength. Moreover this cement-bonded fiberboard can pass the required standard. The high strength and thermal insulation cement-bonded fiberboard from coconut meal corncob fibers and steel wire mesh has the possibility to construction as exterior building wall.

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 1110.58 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.

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 2014.54 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.

The objectives of this research are to study the production step proper ratio physical properties mechanical properties thermal insulation and sound insulation efficiency of concrete blocks mixed with coconut shell ash. The ratios of concrete block mixed with coconut shell ash include Portland cement type1: quarry dust: coconut shellash which equal to 1: 6.8: 0.2 1: 6.7: 0.3 1: 6.6: 0.4 1: 6.5: 0.5 and 1: 6.4: 0.6 by weight. Water per cement ratio are 0.6 by weight. The concrete block samples were casted by the general production as same as the ordinary concrete blocks and were tested follow TIS.58. From the results the best amount of coconut shell ash which put into concrete block is 1: 6.7: 0.3 of ratio. The proper ratios of coconut shell ash can decrease the density or weight and increase the thermal insulation and sound insulation efficiency of concrete blocks. However the high amounts of coconut shell ash effect to decrease the mechanical properties concrete blocks that are lower than TIS.58 standard.
