This research aims to test the properties of concrete block mixed with basalt fragment as aggregates in products. The mix ratios of Portland cement type1 : basalt fragment : water are 1 : 10 : 0.7 1 : 10.5 : 0.7 1 : 11 : 0.7 1 : 11.5 : 0.7 and 1 : 12 : 0.7 by weight. The concrete block samples were mixed and casted in 7 x 19 x 39 centimeter by the concrete block molding machine. The concrete block sample testing follows the TIS 58-2533 standard on non-load bearing concrete blocks. From the results the density compressive strength and thermal conductivity of concrete block mixed with basalt fragment are lower than the common concrete block. In addition the water absorption and volumetric change are higher than the common concrete block. The optimal ratio in this work is 1: 11: 0.7

This research aims to study the using rock fragments of basalt mining to develop paving block product. The mixture ratios of Portland cement type1: basalt rock fragments: tap water are 1 : 4 : 0.45 1 : 4.5 : 0.45 1 : 5 : 0.45 1 : 5.5 : 0.45 and 1 : 6 : 0.45 by weight. The paving block samples are cast in 30 x 30 x 5 centimeter in dimension. The paving block sample testing follows the TIS 378-2531 on concrete flooring tiles. From the experiment bending strength of paving blocks with high quantity of basalt rock fragments is lower than paving blocks with low quantity of basalt rock fragments but the water absorption of paving blocks with high quantity of basalt rock fragments are higher. However all of basalt rock fragments paving block samples with lower than 1 : 5.5 : 0.45 of ratio can pass the standard.

This research aims to study the using oil palm fiber to develop ceiling board product. The mixture ratios of Gypsum plaster: oil palm fiber: tap water: catalyst are 1 : 0.15 : 1: 0.03 1 : 0.20 : 1: 0.03 1 : 0.25 : 1: 0.03 1 : 0.30: 1: 0.03 and 1 : 0.35 : 1: 0.03 by weight. The ceiling board samples are cast in 30 x 30 x 1 centimeter in dimension. The ceiling board sample testing follows the TIS 219-2552. The results show that the longitudinal and lateral breaking load Nail pull resistance density and thermal conductivity of ceiling board with high quantity of oil palm fiber are lower than ceiling board with low quantity of oil palm fiber while that the deflection and water absorption of ceiling board with high quantity of oil palm fiber are higher. However all of oil palm fiber samples with lower than 0.2 of ratio can pass the standard.

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 basalt rock fragments to develop as interlocking block product. The mixture ratios of Portland cement type1: basalt rock fragments are 11 : 6 1 : 6.5 1 : 7 1 : 7.5 and 1 : 8 by weight and water per cement ratio was 0.6 by weight. The interlocking block samples are cast in 10 x 20 x 10 cubic centimeter of dimension with manual compression molding machine. The interlocking block samples were tested in accordance with TCPS 602-2547 standard which subjected for the interlocking block. The results show that the weight compressive strength and thermal conductivity of interlocking blocks with high quantity of basalt rock fragments are lower than interlocking blocks with low quantity of basalt rock fragments while that the water absorption of interlocking blocks with high quantity of basalt rock fragments are higher. From this research the medium and small enterprises could choose the proper ration for the interlocking block production mixing basalt rock fragments as per requirement.
