The objective of this research is to develop the concrete flooring tile product from old asphalt road waste. The 6 ratios of Portland cement type1: coarse sand: old asphalt road waste: water reducer type A: tap water were designed including: 1: 5: 0: 0.02: 0.4 1: 4.5: 0.5: 0.02: 0.4 1: 4: 1: 0.02: 0.4 1: 3.5: 1.5: 0.02: 0.4 1: 3: 2: 0.02: 0.4 and 1: 2.5: 2.5: 0.02: 0.4 by weight. The concrete flooring tile casted with the compressive machine. The property tests followed the TIS.378 - 1988 (concrete flooring tiles). According to the result it was found that the 1: 2.5: 2.5: 0.02: 0.4 was the proper ratio of the concrete flooring tile. The increasing of old asphalt road waste in concrete flooring tile effected to decrease the water absorption and thermal conductivity properties. In term of the density and bending strength properties there were not many differences. The developed concrete flooring tile product from old asphalt road waste can use as same as the common concrete flooring tile product in market.

This Research is to Study the Development of 6k White Gold Low Alloys Metal for Jewelry Production The Optimum Conditions for Casting Jewelry and Jewelry were Investigated. The Results of the Experiments Show that the Chemical Composition of the 8k White Gold Low Alloys is Slightly Different when Compared with XRF (X-ray Fluorescence Spectrometers) Pre-and Post-Melting Quantities The Heat of the Test Specimen was found to be 33.33%Au+50.67%Ag+10%Cu+5%Zn+1%Sn33.33%Au+50.67% Ag+8% Cu+7%Zn+1%Sn and 33.33%Au+50.67%Ag+8%Cu+8%Zn+0%Sn It is Found that the Heat from the Beginning to the Level of Change before the Liquid is used the Average Temperature of 458.9 – 326.3 Degrees Celsius Respectively 33.33%Au+50.67%Ag+8%Cu+7%Zn+1%Sn It is the Formula that Gives the Lowest Value of Liquid State Change from 326.3 Degrees Celsius to the Best Value of this Experiment. Suitable for use in the Manufacture of Jewelry due to its Melting Ability for Molding. Melting for Molding and Formed by Hand. The Amount of Zinc(Zn) may be an Important Factor in the Variation which is Directly Proportional to the Maximum Increase in the Final order of 7 Percent

The purposes of the research were to 1) study the attributes of the graduates according to standards of learning outcome 2) study the 21st century skills of English for International Communication graduates desired by employers 3) compare the attributes of the graduates according to standards of learning outcome categorized by the individual factors and 4) compare the employers’ requirements to skills of English for International Communication graduates categorized by the individual factors. The population were 55 employers participating in the cooperative education project in the academic year 2017. The research tools were questionnaires and interviews which were analyzed by the SPSS program. The statistical data analysis was performed by frequency percentage mean standard deviation and Fdistribution and the interview data analysis was performed by frequency and content analysis. The results were found as follows. 1. As for the employers information33emoloyets were from private and service businesses (60%) and 14 employets were from government sectors (25.50%).As for the working statuses29 employers were the officers (53.70%) 20 employer were the supervisors (37.00%) and 5 employers weie mangers (9.30%) 2. The overall requirement of hte employers for the attrbutes of the graduates according to standandards of learning outcome was at the high level (=4.48). As for each attribute morals and ethcs were the most desirable (=4.75) the second highest level was interpersonal skils and accountabiliy (4.57) and the last one was the intellectual skills (=4.25) 3. The overall requirement of the ernptoyers for the 21st century skills of the graduates was at the high level (=4.43). As for each attribute the highest level was enthusiasm collaboration and thinking skills respectivrty (=4.634.58 and 4.54) The lowest tevel was the inquiry skills (=4.07). 4.The results of the research hypothesis were; 4.1 There was a significant difference between the employers with different employrment sectors (government and service business sectors) and the requirement of the graduates attributes. There was no significant difference between the employers with different working status and the requirement of the graduates attributes. 4.2 There is no significant difference between the employers with diferent employent sectors and working status and the requirement of the graduates attributes.

This research aims to study the water hyacinth fiber inside high-density fiber cement 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 with the steel grating inside. By compressing the mixture cast machine at normal temperature (30 - 35 °C). From the test results the ratio of B4 is the appropriate ratio from the 1st year research result to produce the high-density fiber cement board with the steel grating inside 0.81mm #0.5”. It can pass the TIS 878-2537 standard of Cement Board and good based-on high density and physical properties mechanical properties and thermal insulation. Accelerate the formation of the most suitable cement is calcium chloride (CaCl2).

The objective of this research is to develop the precast adobe wall panel with high corrosion resistance and good thermal insulation. The ratio of Portland cement type1 clay rice husk ash straw rice husk waterproofed liquid and tap water was mixed and casted as same as the common concrete and reinforced by bamboo. From the results the proper prototype ratio of precast adobe wall panel was Portland cement type1: clay: rice husk ash: straw: rice husk: waterproofed liquid: tap water which equal to 1: 3: 0.3: 0.02: 0.02: 0.02: 0.4 by weight. The properties of the precast adobe wall panel prototype included density 1797 kg/m3 water absorption 16.70% bending strength 2.61 MPa compressive strength 21.40 MPa thermal conductivity coefficient 0.314 watt/m.Kelvin. Moreover the precast adobe wall panel prototype also was verified by TIS.2226-2548 with properties of impact resistance deflection and hardness in medium duty (MD) level. These straw and rice husk effected the precast adobe wall panel to decrease the density bending strength thermal conductivity coefficient and increase the compressive strength and water absorption.
