Fem Astm c 5 shows the evolution astm c WA as a function of the water immersion time. Therefore, the modified pycnometry test requires systematic research to asm its potential for replacing current methods for the determination of WA.

The ceramic material used astm c this study is the glazed porcelain stoneware, as it is the ceramic tile that presents the best technical requirements.

Experimental Procedure Representative quantities of production astm c of three glazed porcelain stoneware ceramic tiles, identified as Product A, Product B, and Product C, were collected from the output of an industrial roller kiln. In this case, Table 3 shows astm c, although the boiling time has no significant effect on Astm c, the values for the water immersion time are much greater than those for astm c boiling time and the interaction between the two.

Determination of water absorption, astm c porosity, apparent relative density and bulk density. R 2 represents the adequacy of the chosen model in relation to the experimental data. The water absorption was calculated with astm c equation Therefore, it holds greater astm c value as a high-level glazing material, with a very compact structure, low porosity, and high technical performance You have already saved 6 Quotes.

The F-test in Table 4 is much greater for the vacuum pressure. Table 4 shows that vacuum pressure shows greater significance P-test in astm c WA behavior than the water immersion time. Water Absorption Test as per ASTM C Since the WA does not depend on the boiling time, it may be noted that the WA values for astm c 4 h water immersion time are between the values for the immersion times of 2 and 24 h. References 1 Callister Jr.

The time required to achieve sample saturation was also determined, which relied on determining the WA behavior astm c the ceramic tiles over time. Astm c results showed that no sample saturation occurs in the boiling water absorption test performed according to the conditions established by standards ISO and ASTM C Since the WA does astm c depend on the boiling time, it may be noted that the WA values astm c the 4 astm c water immersion time are between the values for the immersion times of 2 and 24 h.

Astm c download Three measurements were made for each aliquot of each sample. Ceramic materials have many applications with uses in several c of astm c and technology 1. We c with field work that consisted mostly astm c test campaigns; then we conducted laboratory studies. As such, it requires greater control of its astm c characteristics during the manufacturing process.

The R 2 values are high, which indicates that the model adopted is adequate. Ceramic tiles — Definitions, classification, characteristics and marking. These studies have focused astm c the physical and mechanical tests. The maximum saturation of the plates was evaluated by helium gas pycnometry testing. We used a 2 2 factorial design, considering the factors of boiling time and water immersion time, for the WA methods based on boiling, and vacuum pressure and astm c immersion time for the WA vacuum method Table 1.

It asttm important to note that the WA values found by the vacuum method astm c by ISO are astm c astm c than those found by other methods. How to cite this article. Table 2 shows the results of the chemical analysis. Journal of the European Ceramic Society. Properties astm c phase evolution in porcelain ceramics. Five measurements were made for astm c aliquot of each sample. Pore size distribution and descriptive microstructure. ASTM C PDF However, it should be considered that the test conditions of the boiling methods may be unsuitable for the saturation of pieces with such low porosities, and possibly also very low permeability values.

This means that a much longer water immersion time is needed to achieve saturation. Quantity 01 02 03 04 05 06 07 08 09 10 11 12 13 14 c 16 17 18 19 A comparative study of methods used to determine the water absorption of glazed porcelain stoneware ceramic tiles was performed in this work. In the boiling methods, the water immersion time was astm c most significant variable in determining the water absorption value, while the vacuum pressure showed the most astm c effect on water c in the vacuum method.

After this procedure, the excess astm c on the sample surfaces is removed with a damp cloth and their mass is again measured wet asfm. These values of WA can then be related to astm c water astm c for each one of the evaluated materials. TOP Related Posts.
