This research aims to develop the cement board from vesicular basalt fragment which reinforced with steel wire mesh. The ratio of Portland cement type1: fine sand: vesicular basalt fragment: sodium silicate: tap water was equal to 1: 2: 4: 0.03: 0.55 by weight. The 5 sizes of steel wire mesh (steel wire no.25) were installed including: 3/8” 1/2” 5/8” 3/4” and 1”. 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 the 3/4 of steel wire mesh size was the most suitable size for reinforcing the cement board from vesicular basalt fragment. This developed cement boards was the construction materials which had the high bending strength good thermal insulation and moisture protection properties.

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 using of ground coffee wastes from industries to develop the cement board is an objective of this research that can solve the air pollution problems from smell and spreading of ground coffee wastes. The ratio of Portland cement type1: fine sand: tap water is equal to 1: 0.5: 0.416 by weight and the ratios of Portland cement type1: ground coffee wastes include 1: 0.05 1: 0.06 1: 0.07 1: 0.08 1:0.09 and 1: 0.10 by weight (6 ratios). The production of cement board uses the pressure casting in temperature 30 – 35 degree of Celsius and controls 0.75 g/cm3 of density. The testing of cement-bonded fiberboard properties follow the TIS 878-2537 standard (cement bonded particle board: high density). From the results 1: 0.05 is the most suitable quantity of cement: ground coffee wastes which mixed in cement board. This cement boards can reduce the ground coffee wastes by using as aggregate to produce the construction materials.

This research aims to develop the cement board from coconut shell ash. The Portland cement type1: fine sand: tap water ratio is equal to 1: 0.4: 0.33 by weight. The 5 ratios of Portland cement type1: coconut shell ash include 1: 0.12 1: 0.13 1: 0.14 1: 0.15 and 1: 0.16 by weight. The cement board production uses the pressure casting in normal temperature (30 – 35 degree of Celsius) and controls the 0.75 g/cm3 of density then test the properties of cement-bonded fiberboard follow TIS 878-2537 standard (cement bonded particle board: high density). From the results 1: 0.12 is the most suitable ratio of cement board from coconut shell ash. This developed cement boards can reduce the quantity of coconut shell ash waste and have the good thermal insulation.
