Özet

The aim of this study is investigation of wall stone reproducibility using expanded perlite aggregate as a main raw material. For this purpose, production parameters (burning period, burning temperature, pressing pressure ratio, chemical additive ratio, dimension analysis and water/solid (w/s) ratio and also engineering parameters such as weight per unit of volume, mechanical properties of produced control brick (with a dimension of 50x100x100 mm) were determined and optimized. The most effective values for the brick production were designated by changing optimization parameters like pressing pressure, burning temperature, burning period, holding (curing) time. As a result of the study, the lowest value of weight per unit of volume and the highest value of compressive strength were ascertained as 522.5 +/- 48.3 kg/m(3) and 12.13 +/- 0.13 kg/cm(2) respectively for the samples which were produced at 50 bar pressure and 200 degrees C temperature with 1 h burning period and w/s ratio of 1.0. However, obtained compressive strength values for the control sample produced without using binder were found to lower the standards of TS EN 771-1.
