Development of cement boards with ground coffee for environment conservation
Abstract
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.
