Harman bricks are used on restoration and rehabilitation of historical structures and construction of masonry structures widely since there are plenty of raw materials and easy production technique in Turkey. In this study, alternative use of perlite as an area of light brick production is investigated. Blended harman bricks were produced by conventional methods with fly ash, bottom ash, blast furnace slag on the ratio of 10% which has been included in all mixtures instead of clay. Unit weight, water absorption for 24hours, capillarity, ultrasonic pulse velocity and compressive strength tests were applied in all samples produced from the harman bricks. On the other hand the samples were exposed to ±20°C for 50 and 100 freeze-thaw cycles. Freezing-thawing loss effects were determined using unit weight, ultrasound pulse velocity and compressive strength tests. Unit weight, ultrasound pulse velocity and compressive strength of blended or normal bricks were determined.
