Abstract

Calcium silicate ceramics have been made using natural ingredients such as rice husk and snail shell with solid reaction techniques. The aim of this study to determine the characteristics of calcium silicate that have been sintered at a temperature of 900 °C, 1000 °C, and 1100 °C. Samples were characterized by X-Ray Diffraction (XRD), optical microscopy, and Fourier Transform Infra-Red (FTIR). The results of XRD characterization showed that CaSiO3 (calcium silicate) along with the increase in calcination temperature and quantity was increased due to the increase of temperature of calcination. FTIR analysis showed that the Ca-Si-O bond was formed at wave number ranging from 848 cm-1 and 999 ? 1001 cm-1.

Abstract

Abstract.  Study about the influence of sintering temperature on mechanical properties of ceramics has been done using clay and rice husk ash. Limitation of mechanical properties tested is the comppressive strength. This is done in order to determine the effect of variation of sintering temperature to compressive strength of ceramic with clay and rice husk ash. In addition, the calculation of fuel density and shrinkage also performed in this study. Variation in the composition of clay and rice husk ash is made to see the maximum composition of these materials. The result shows that the density of the ceramic material on the composition of  clay and rice husk ash volume 100: 0, 90:10, 80:20, 70:30, 60:40, and 50:50 are 2.14; 2.01; 1.98; 1.88; 1.84; and 1.78 g / cm3 respectively. Shrinkage of ceramic material has ranges between 3.4% -11.4%. The value of maximum compressive strength of clay and rice husk ash ceramic at 7000C, 8000C, and 9000C sintering temperature are 115.58; 115.58, and 128.42 kg / cm3. This value conforms the standard if used for bricks. The greater the sintering temperature, the higher the compressive strength of the ceramic. The best composition of clay and rice husk ash is 70:30. This ceramic can be used as building material, especially in the swampy area because it has a lighter weight. Keywords: Ceramics, Clay, Rich husk ash, comppressive strength

Abstract

Characterization of wood waste from halaban wood, bottom ash, and coal fly ash has been done includes tests of water content, ash content, calorific value, and composition as well as morphology. One of the factors that influences the characteristics is the powder size. Therefore, this research uses 250 mesh sieve (smaller powder size) to make briquettes. From the test results, the average moisture content was 4.22% for halaban wood charcoal, 1.64% for bottom ash and 0.91% for fly ash. Average ash content of 41.93% for halaban wood charcoal, 82.03% for bottom ash and 89.69% for fly ash. Average Calorie Value of 6833.1 cal/g for halaban wood charcoal, 389.5 cal/g for bottom ash and for coal fly ash with calorie value of 0. From the SEM-EDX analysis results, there was no C mean of 76.69% In halaban wood charcoal, the average ash percentage of C was 41.87% and the average percentage of C was 16.17% in coal fly ash. The results of tests carried out are expected to be waste wood charcoal, basic ash and fly ash can be used as a mixture in the manufacture of briquettes.
