End: Square – factory cut Gypsum blocks vary in thickness, density and type. In the U.S. gypsum blocks were made in thicknesses of 2, 3, 4 and 6 in (51, 76, 102 and 152 mm). In Europe they are available in thicknesses of 60 mm, 70 mm, 80 mm or 100 mm. In European residential buildings regularly 80 or 100 mm thick gypsum blocks are being used.Recent studies have mainly focused on producing gypsum boards with increased fire resistance, water resistance, and low density. The production of multi-layer thermal insulating boards using coal combustion by-products was patented in 2003 by Stache and Kahl (2003).density, moisture content and porosity of the material. Such sensitivity contributes to the diverse data reported in litera-ture as demonstrated in Fig. 5. Assuming gypsum is made of solid substrate and uniformly distributed spherical pores, the effective thermal conductivity of gypsum may be calculated using the following equation [6]: kk kk ...

Mar 1, 2017 · This reduction is directly related to the density of EPS (Fig. 7). In addition, as tragacanth addition ratios increase, their density values decrease, which is caused by the artificial pores that occurred later. The tests applied to the samples showed that density depending on EPS ratios, 20% and 80%, decreased by 51.56% (sample 1, sample 4).
