การพัฒนาผลิตภัณฑ์ผนังคอนกรีตมวลเบาด้วยการเสริมแผ่นโฟมอัดแน่น เพื่อเป็นฉนวนความร้อน
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.
การพัฒนาผลิตภัณฑ์ผนังคอนกรีตมวลเบาด้วยการเสริมแผ่นโฟมอัดแน่นเพื่อเป็นฉนวนความร้อน
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 develop the structure to create the knowledge of construction technology to test the properties to construction the prototype building and to transfer the technology of hemisphere pre-engineered building with easy assembly steel structure type. The load and resistance factor design (LRFD) method was used to design the structure by regarding the strength material type construction and deconstruction step and cost. From the design the prototype of hemisphere pre-engineered building (only the frame structure) was construction with 5 meters of diameter 3.5 meters of height 19.635 square meters of useful space 200000 Baht of material cost (10186 Baht per square meter for all materials) 27 hours or 3 days of construction period. According to the modular coordination system this hemisphere pre-engineered building cans construction and deconstruction fast especially when apply to help disaster victims. After tested the structure that the calculation value of safety factor (S.F.) is 1.76. Moreover these results can register the copyright and draft the research paper to transfer the technology for target group.

The objectives of this research are to study the production to find the proper ratio to test the properties to suggest the implementation and to transfer the technology of high strength milk carton waste artificial wood mixed with poly ethylene terephthalate (PET) plastic waste. The ratios of this artificial wood included milk carton waste: PET plastic waste equal to 80:20 75:25 70:30 65:35 and 60:40 by weight. The milk carton and PET plastic wastes were grinded though sieve no.4. The artificial woods were casted by hot compression with 180 degree of Celsius for 5 minutes. The samples tested follow the TIS.966-2547 standard. From the results the 60:40 of ratio was the proper ratio which can pass the standard. The increasing of PET waste effected to decrease the density moisture and swelling of properties. In case of bending strength elastic modulus and tensile strength perpendicular to surface the increasing of PET effected to decrease their properties. The developed artificial wood mixed with milk cotton waste and PET plastic waste has the possibility to implement in decoration and construction both interior and exterior wall building. These results can register the petty patent and write the research paper which to transfer the technology.

The objectives of this research are to develop the knock down house to create the knowledge to test the properties to construction the prototype and to transfer the technology of easy transport knock down house for sufferer. The load and resistance factor design (LRFD) method was used to design the structure. From the design and testing the easy transport knock down house for sufferer is the square shape building with gable roof. The building size 4.00 x 4.00 square meters and height 2.40 meters which has 16.00 square meters of usable area and 1.20 meters of gable roof height. This knock down house can separate the usable area into 2 parts include bedroom and toilet. The cost of material is 125000 Baht per unit or 7812.5 Baht per square meter. The 6 wheel truck can transport this knock down house. The safety factor (S.F.) of this knock down house equal to 1.86. Moreover the knowledge can register the copyright names “The drawing of easy transport knock down house for sufferer” and draft the research paper names “The easy transport knock down house for sufferer” that are the way to transfer technology to target group.
