Y UNE EN 196-1: 2005 applying a IMAL Universal Testing Machine. Compression test: The test pieces were tested according to the UNE -EN 13279-2 [24] common. A universal compression testing machine was made use of having a load speed 1 N/mm2 /s. Setting time test: The standardized knife approach was made use of as stated in UNE-EN 13279-2 standard [24]. This was carried out in parallel at the similar time as the formation of your specimens. Micrograph test: Schottky hot cathode field emissions had been obtained working with a Zeiss Sigma 300 VP scanning electron micrograph (ZEISS, Oberkochen, Germany). The tested specimens all measured 40 40 160 mm. For each dosage, 12 specimens have been created in 3 test batches, providing 36 units in total for the flexural strength, direct modulus of elasticity, compression, and Shore N1-Methylpseudouridine site hardness, tests. For the statistical study, SPSS was made use of, allowing comparison of your means utilizing ANOVA with Duncan’s test for a self-confidence interval of 95 , at the same time as Tukey’s test for multiple comparisons from the t levels of each aspect. Also, the independent situations had been obtained to permit a summary of the means and normal deviation. three. Outcomes In all of the tests, SUL Y1 plaster without the need of additives was made use of because the control, using a water/plaster ratio (A/Y = 0.five) of 50 . Table 4 shows the results obtained for the mechanical properties of your distinctive batches of test pieces containing different additives.Table four. Average benefits and regular deviation for reference Y1 without the need of additives.

Discussion By analyzing Table 4 in relation to the reference (SUL) Y1, making use of the same percentage of mixing water, we are able to observe that the calcium sulfate already has very good mechanical properties.
