This research aims to study the water hyacinth fiber inside high density cement fiber board. By using ratio components among cement : fine sand : water hyacinth fiber : water : catalyst accelerated the formations of cement (aluminum sulfate (AI2 (SO4) 3) calcium chloride (CaCl2) sodium silicate (Na2SiO3)) on the ratio 1: 0.2: 0.075: 0.3: 0.03 by weight of total water hyacinth fiber. The 5 ratios consist of 0.0 (A1 D1 formulae) 0.025 (A2 B2 C2 D2 formulae) 0.050 0.03 (A4 B4 C4 D4 formulae) and 0.1 (A5 B5 C5 D5 formulae) by weighted all fibers were treated with sodium hydroxide solution (NaOH) at a concentration of 12%. The fiber to solution ratio was 1: 10 boiled in open system at 100 °C for 1 - 3 hours. By compressing the mixture cast machine at normal temperature (30 - 35 °C). Use a density of 0.75 g / cm3. From the test results the ratio B4 is the appropriate ratio. Can pass TIS 878- 2537 Cement Board: high density and physical properties mechanical properties and thermal insulation are good. Accelerate the formation of the most suitable cement is calcium chloride (CaCl2)

This research aims to study the development of the Para rubber press machine with wrought pattern for continued 2-year project. Used natural Para rubber mixed in ta-Kuong by normally practical Para rubber farmers to evaluate the rubber press machine. It has developed the 11 roller the 3 plain duo sets of normal press rollers and the 2 duo sets of wrought rubber press rollers with the induction motor at 1430 rpm. The rotating transmission based on belts and chains. The evaluated results produced the dried Para rubber sheets thickness at 3.75 mm. on average as standard market need. From a robber sheet with enough patted on with a worker to carry the ta-Kuong to a top tray and a rubber press man to put the Para rubber piece to a machine on average the completed 185 wrought rubber sheets per hour in shorter time.

The Kaolinite development process to improve the characteristics. The Kaolinite mixed ratios are 10% 20% 30% and 40% and the result indicated that the experiment mortar-mix ratio at 0:8:2.75:0.2:0.05:0.04:0.5 of cement powder sand Kaolinite limestone superplasticised and clean water compared to No MK control sample covered ASTM standard in tensile strength more than 100 ksc compressive strength of MK20% with superplasticised at 434 ksc. The water absorption values under the standard passed

The purpose of this research is to improve the physical and mechanicalqualities of natural rubber latex tiles. Water: surfactant: surfactant: 1: 2.75: 0.03: 0.30:0.03: 0.04 by weight and added with natural latex. In the ratio of Portland Cement Type 1: Natural Latex is 1: 0 1: 0.025 1: 0.05 1: 0.075 and 1: 0.10. Formed with compression presses at normal temperatures it was found that the optimum amount of natural latex For concrete reinforced concrete tiles the ratio is 1: 0.025. The tests in accordance with Thai Industrial Standard TIS 535-2556 are tested in 4 aspects. Dimensional stress test Water absorption test And waterproofness testing The value has passed the benchmark. And low thermal conductivity. Increasing the insulation of the roof as well. Can be used as a prototype product tile concrete roof natural latex. To produce commercially And there can be many local latex or rubber latex. To be more useful and valuable.

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. The envelope of this building used the ratio of Portland cement type 1: fine sand: coconut fiber: waterproofed liquid: tap water which equal to 1:3: 0.1: 0.02: 0.5 by weight and reinforced by round bar and wire mesh steel. According to the testing the building-envelope properties are following: density 1582 kg/m3 thermal conductivity coefficient 0 .3 7 1 watt/m.Kelvin water absorption 1 7 .3 1 % compressive strength 118.47 ksc and bending strength 28.88 ksc. Moreover these results can register the copyright and draft the research paper to transfer the technology for target group.
