In this study; the usability of pumice aggregate on the production of non-bearing partition panel wall, is studied. In order to produce mortar specimens, mix designs are performed according to TS EN 196-1, molded and cured accordingly. Bending strengths were measured on 40x40x160 mm specimens and compressive strength test was performed on the broken parts having a surface area of 40x40 mm after bending test on the 7th and 28th day cured mortar prism samples according to TS EN 196-1. Water demand of mortar mixtures was determined according to standards by using flow table of 110 ± 5%. Specimens were molded using rate of % 0-1-2-3 super plasticizer additive at cement dosages of 200-300 -400 -500 kg/m3 and water / cement ratio of 0.4%. The highest 28th day compressive strengths are obtained from the specimens of 3 % super plasticizer admixture with 500 kg/m3 cement dosages. Results obtained from these samples showed a significant increase compared to the others. There is no difference between the compressive strengths of 2% super plasticizer chemical admixture added samples and the samples of no additive. Maximum bending strength of the mixtures was obtained at 7th day of mixtures of 500 kg dosage. Here, bending strengths of mixtures are increasing with increasing the usage rate of the chemical admixture. However, there is no big differences between bending strength increases of 2% and 3% chemical admixture were observed.
