In recent years, the use of natural and light aggregates in the construction industry has become increasingly common. Light mortar applications for insulation purposes have become one of the important issues of today, especially in composite structure produced with light aggregates. In this context, vermiculites, which have reserve potential in our country that can be evaluated in the light aggregate category in this study but are known only for use in the agricultural sector, were used as the main raw material. Cement-based Vermiculite aggregate polymer additive mortar mixture designs were made and analyzed on a series of plaster samples. In addition, in order to make technical comparison in the experimental study, these samples were compared with control samples prepared without vermiculite aggregate polymer components and analysis results. According to the findings, the dry unit volume weight values of the polymer component composite mortar samples are between 560 kg/m3 and 659 kg/m3, respectively, the compressive strength values are between 0.94 N/mm2 and 1.81 N/mm2, and the capillary water absorption rate is 0.328. kg/m2min0.5-0.249 kg/m2min0.5, thermal conductivity coefficients were measured as 0.083 W/mK-0.094 W/mK. In the control samples, the technical findings were determined as 780 kg/m3, 2.64 N/mm2, 1.620 kg/m2min0.5, 0.156 W/mK, respectively. These results have shown us that the heat-treated vermiculite aggregate can be evaluated in the production of thermally insulated composite mortars with low unit volume weight, especially when used with polymer additives.
