Özet

Energy saving is the most important parameter for energy efficiency. To use energy efficiently without any reduction in production, comfort and work power; energy saving is needed. Energy efficiency of buildings is primarily necessary in order to save costs and also reduce the amount of CO2 emission and greenhouse gases in the atmosphere. In recent years, thermal insulation with different originated materials has been studied. In order to maximize energy saving, more attention should be paid for the selection of appropriate construction materials which can be utilised for insulation. In this experimental study, cement mortars with different fine aggregates were prepared and compared by means of physical, mechanical and thermal properties. The results showed that acidic pumice aggregate mortar had higher capillar absorption and lower thermal conductivity than the basic pumice aggregate mortar. It is also found that mortars with porous slag had the lowest strength values and the highest permeability. However, they exhibited the best performance among other mortars in thermal properties.
