In this study, the use of diatomite, which has a high pozzolanic property, in light concrete block production was investigated. After the high temperature and freeze-thaw effect of some 10x10x10 cm cube samples produced using aggregates with different grain distributions (granulometry) with cement dosage (220 kg/m3) and water/cement ratio (0.15) constant. Changes in properties are examined. For experimental studies, aggregates were produced in 5 different series with 0-4 mm (fine), 4-8 mm (medium) and 8-16 mm (large) grain distribution ratio. Physical changes occurred in samples after high temperature and freeze-thaw effect were determined by determining unit volume weight, porosity, ultrasound, compressive strength and elasticity module values on 28 days of hardened samples. In the results of the experiment, it was observed that the unit volume weight values varied between 1182,33- 1273,37 kg/m3, after freezing-thawing, a decrease in compressive strength was observed along with an average 8.53% mass decrease with crumbling and breaking down. While an average mass decrease of 7.9% occurred with high temperature effect (600 oC), an average increase of 55.22% was observed in compressive strength.
