The aim of this study is investigation of brick reproducibility using expanded perlite aggregate as the main raw material. Na-Borate and K-Borate are used as additive material in the production of perlite bricks. Engineering parameters such as weight per unit of volume, mechanical strength of produced control brick (with a dimension of 50 × 100 × 100 mm) were determined and optimized. As a result of the study, the lowest value of weight per unit of volume and the highest value of strength were ascertained as 522 kg/m3 and 23 kg/cm2 for the samples which were produced at a 50 bar pressure and 400 °C with 1 h burning period and a water to binder ratio of 0.90. Also, denser volume was observed in the microstructure investigation by addition of Na-Borate and K-Borate to perlite brick mixtures.
