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 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

This research is aimed at studying the development of strong and high strength fiberboard from coconut fiber and corn plant. This is the second consecutive year by using natural latex. To enhance thermal insulation performance. By using the cement ratio: fine sand: coconut pulp: corn fiber: water: surfactant: surfactant is 1: 0.2: 0.0125: 0.0375: 0.3: 0.03: 0.04 by weight Then add natural rubber latex at cement ratio: 5: 1 ratio of natural rubber latex: 1: 0.05 1: 0.10 1: 0.15 1: 0.20 and 1: 0.25 by weight tested in accordance with TIS 878- 2537 on cement slabs. : High density the test results show that the ratio of 1: 0.05 is the fiber cement ratio. The most appropriate the amount of natural latex said. Can make fiber Cement sheets. Best compression and bending strength. And has passed the standard TIS 878-2537 cement fiberboard developed this can help reduce the amount of natural latex is very high. And have a good thermal insulation properties

This research aims to study the using oil palm fiber to develop cement-bonded fiberboard product. The mixture ratios of Portland cement type1: fine sand: oil palm fiber:tap water: catalyst are 1 : 1.95 : 0.05 : 0.40 : 0.03 1 : 1.94 : 0.06 : 0.40 : 0.03 1 : 1.93 : 0.07 : 0.40 : 0.03 1 : 1.92 : 0.08 : 0.40 : 0.03 and 1 : 1.91 : 0.09 : 0.40 : 0.03 by weight. The cement-bonded fiberboard samples are cast in 30 x 30 x 1.5 centimeter in dimension. The cement-bonded fiberboard sample testing follows the TIS 878-2537. The results show that the density thermal conductivity bending strength modulus of elasticity and tension perpendicular to surface of cement-bonded fiberboard with high quantity of oil palm fiber are lower than cement-bonded fiberboard with low quantity of oil palm fiber while that the water absorption and swelling in water of cement-bonded fiberboard with high quantity of oil palm fiber are higher. However all of oil palm fiber samples with lower than 0.06 of ratio can pass the standard.

This research aims to study the using cassava pit wastes mixed with cement to particle board walls. The Portland cement type1: fine sand: tap water ratio is equal to 1: 0.5: 0.416 by weight. The ratios of cassava pit wastes to cement are used following: 0.05 0.06 0.07 0.08 0.09 and 0.10 by weight. The cassava pit wastes are crushed by plastic plastics granulators (pass sieve no.4). The casting of particle board walls use the compression machine in room temperature (30 – 35 degree of Celsius) and control 0.75 g/cm3 of density. The TIS 878-2537 standard (cement bonded particle board: high density) is followed to test the properties of particle board wall. Resulting the cassava pit wastes mixed with cement can cast to particle board walls and have good properties especially the thermal insulation property.
