RESULTS AND DISCUSSION
5.1 Compression Test The compression test results for Granite epoxy specimens is documented and listed in Table 5.1.
Table 5.1 Compression Test results for Granite Epoxy Specimens Figure 5.1 shows the compressive strength plot of granite epoxy composite specimens without the inclusion of filler material. From the graph, it is observed that the compressive strength of the fabricated specimen’s increases up to 70% granite content and further decreases with the increase in epoxy percentage. The maximal compressive strength obtained is 112MPa for 70:30 granite epoxy ratio.
The graph of modulus of elasticity of granite epoxy specimens is represented in figure 5.2. The maximum elastic modulus of compressive specimens
By analyzing the graphs, we find that the compressive strength of the specimens is higher for 10% addition of cast iron filler material. The maximum compressive strength value obtained is 123MPa for a Granite epoxy ratio of 75:25 for 10% filler material.
Table 5.2 Compressive Strength of Granite Epoxy Specimens with Cast Iron Filler Material
Figure 5.4 shows the elastic modulus plot of granite epoxy composite specimens with the presence of cast iron as filler particles. The modulus of elasticity is found to be higher for 10% of filler material. The elastic modulus of the specimens decreases with the increase in epoxy content. Maximum elastic modulus is found to be 4.365GPa for a ratio of 85:15 with 10% cast iron content; hence this material has very high stiffness values.
5.2 Tensile Test The tensile test results for all granite epoxy specimens are recorded and tabulated in the table
From the plot, it is understood that damping values of the specimens have shown slight improvement by the addition of 5% cast iron particles as filler material. Higher damping values are obtained for granite epoxy ratios such as 80:20, 75:25, 60:40 and 50:50 with 5% filler material. The damping values results in a moderate drop with the increment in filler percentage in the specimen. The logarithmic decrement curve is similar to the damping curve with better values obtained by the addition of 5% filler

After resin impregnation in the TBC, the gel was stretched in the same way as the BC and the mechanical properties of the final composites were investigated to understand the efficacy of the stretching process. It is well-known that porosity should be reduced as much as possible in a composite material since the stress transfer between fiber and resin is negatively influenced by the pores.[24] The porosity in the composites was calculated according to the equation: Porosity=(1-ρ_c/(w_f ρ_f+w_r ρ_r ))×100% , where ρc, ρf, ρr, wf, and wr are the bulk density of composite, density of TBC, density of SPI, weight fraction of TBC, and weight fraction of SPI, respectively.[25] The porosities in both composites were calculated to be in an acceptable range of 2.0-3.5%. The fiber content in both composites was maintained at about 42 ± 2 wt% based on the previous studies by controlling the viscosity of the resin. Figure 8 shows the FESEM images of surfaces of control and stretched TBC-SPI composites. As can be seen from Figure 8, the resin filled the pores effectively in both composites. Also, the surface of control TBC-SPI composites showed random undulations (Figure 8a) while stretched TBC-SPI composites had a much smoother surface (Figure 8b). The formation of smoother surface can be…

Manufacturers of tumbled tiles literally put the stones through a tumbling process. This means they are placed in a drum that is filled with abrasive materials. It includes a mixture of water, rocks, sand and other abrasive materials that cause the stones to age and achieve a distressed look. The drum is then turned or tumbled in order to create the unique finish. This marble is usually cut in larger proportions and is of thicker width.…

Rock specimen “A” is identified as marble. This sample had a white to cream color to it, which is an identifying characteristic of marble. Another characteristic is the calcite inclusion; this inclusion is seen by bubbling when exposed to a saturated citric acid solution. When viewed by the unaided eye, the grain and crystal structure is clearly seen. While marble is supposed to be a fairly soft rock, the example provided proved to be fairly durable which was tested using a small hammer. Repeated strikes with moderate force yielded only small chips. Marble is a metamorphic rock that formed from limestone with calcite inclusions that was exposed to increased heat and pressure. Like sample “A”, rock sample “B” was also a metamorphic rock.…

In this study, the main object is to find out the hardness change due the carbonized and non-carbonized alloys in air cool or water quench’s hardness differences. And the result showed that the carbonized with in air cool samples to compare with the normal air cool without covered carbon powder were similar, but the one covered with carbon were increased the overall hardness than the one without. On the carbonized with water quench it showed the one covered with carbon can provided more hardness (twice or more) than the center and also the one without covered carbon.…

The influence of EP parameters on the surface roughness is using main effect plot as shown in Fig.2. The surface roughness decrease with increase in temp. When time increase from 9 min to 12 min there is decrease in surface roughness but from 12 min to 15 min there is no change in surface roughness. In third case, when current density increase from 0.0054 A/mm2 to 0.0058 A/mm2 , there is decrease in surface roughness but from 0.0058 A/mm2 to 0.0062 A/mm2 again surface roughness will be…
