This research aims to produce the T-BAR particleboard from Physic nuts for interior building which are brought agricultural wastes to used for beneficial materials. Under the Thailand industrial standard (TIS-876-2547) specified the evaluated values such as desnsity water content water absorption thickness swelling bending strength elastic modulus and internal bonded. The experiment and evaluation processes between Physic nuts per Urea Formaldehyde ratio and Physic nuts per Phenol-cyanate based on 90:10 92:8 95:5 and 97:3 in consequence that we found the thickness of particleboard not more than 2 cm. The suitable ratio for Phenol-cyanate 92:8 percentage (Physic nuts 92% with Phenol-cyanate 8%) and suitable ratio for Urea Formaldehyde 90:10 percentage (Physic nuts 90% with Urea Formaldehyde 10%) at 120 Celsius temperature on pressing process. The Phenol-cyanate glue ratio of 0.80 gram per cubic centimeter suited to produce the particleboards averaged water content before pressing 8.89% suitable pressure in process 150 pound per square inch water content 7.65% density 0.818 gram per cubic centimeter water absorption 14.23% during 2 hours thickness swelling 8.02% during 2 hours internal bond 0.56 MPa bending strength 21.45 MPa modulus 2116 MPa. The Urea Formaldehyde glue ratio of 0.82 gram per cubic centimeter suited to produce the particleboards averaged water content before pressing 9.84% suitable pressure in process 152 pound per square inch water content 8.63% density 0.833 gram per cubic centimeter water absorption 14.36% during 2 hours thickness swelling 8.95% during 2 hours internal bond 1.39 MPa bending strength 22.37 MPa modulus 2117 MPa. As the results shown that both of Urea Formaldehyde and Phenol-cyanate with Physic nuts passed the TIS 876-2547 standard. The Physic nuts can produce the particleboards for using inside building.

This research aims to develop the ceiling board mixed with coconut coir. The 5 ratios of gypsum plaster: coconut coir: sodium silicate: tap water are equal to 1 : 0 : 1: 0.03 1: 100: 1: 0.03 1: 150: 1: 0.03 1: 200: 1: 0.03 1: 250: 1: 0.03 และ 1: 300: 1: 0.03 by weight. The ceiling boards were produced by casting in normal temperature (30 – 35 degree of Celsius). The properties testing of ceiling board mixed with coconut coir followed the TIS 219-2009 standard (gypsum plasterboard) including: breaking load nail pull resistance deflection water absorption density and thermal conductivity coefficient. From the results 1 : 1 5 0 : 1: 0.03 is the most suitable ratio of ceiling board mixed with coconut coir. This developed ceiling boards can reduce the quantity of coconut coir waste and get the good thermal insulation ceiling board products

This research aims to develop the cement board from vesicular basalt fragment. The 5 ratios of Portland cement type1: fine sand: vesicular basalt fragment: sodium silicate: tap water are equal to 1: 2: 0: 0.03: 0.5 1: 2: 2: 0.03: 0.5 1: 2: 4: 0.03: 0.55 1: 2: 6: 0.03: 0.6 and 1 : 2 : 8: 0.03: 0.65 by weight. The cement boards were produced by compression machine. The property tests of cement-bonded fiberboard followed the TIS. 878-1994 standard (cement bonded particle board: high density). From the results 1: 2: 4: 0.03: 0.55 is the most suitable ratio of cement board from coconut shell ash. This developed cement boards can apply the vesicular basalt fragment to use as the construction materials with light-weight high strength good thermal insulation and moisture protection properties

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.

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.
