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 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.

The objectives of this research are to select basic recipe for bread sticks fine proper amount of raw salted egg white to add to bread sticks study acceptance of bread sticks enriched with raw salted egg white and to study the change in amounts of protein in basic recipe of bread sticks and the raw salted egg white added one. The products were evaluated by sensory method regarding color odor taste texture and overall acceptability using 9-poin Hedonic scale. These bread sticks enriched with raw salted egg white used the egg white left over from the egg yolks used in the making of Chinese pastry (Kanom Pia) This research found the recipe to be best accepted. The study of proper amount of raw salted egg white at 5 10 and 15 percent added to the basic recipe found that 10 percent of raw salted egg white received the highest acceptance. Consumers accepted 10 percent raw salted egg white enriched bread sticks at the highest level of 37.5 percent. The study of protein content of raw salted egg white enriched bread sticks were a little higher than the basic recipe. Keyword : Bread Sticks Raw salted Egg white

A comparative study. The purpose was to study the costs and the cost of return. Comparative analysis of the difference between revenue and the cost of return breakeven Between brackish and salt water fish white snapper. This study used data from interviews with of 24 cases. The period 6% of Interest rate of study 5-year. - A study of the brackish cost per acre was 355127.00 baht Salt water 31556.34 baht cost was 850784.15 baht Salt water 788305.00 baht Income yield 1914250.00 baht. and Salt water 1908750.00 baht. the cost according to the net present value (NPV) were positive value equal 620881.68 baht Salt water 628974.65 baht and the internal rate of return (IRR) 16.95% Salt water 17.45 % with a payback period of 1 year 9 months 6 days Salt water 1year 8 months 4 days and the breakeven point is equal to 96529.25 baht Salt water 86643.80 Baht. - The salt water yield worthwhile than brackish water.
