| Light construction materials solve many problems such as earthquake, economy, heat and sound insulation, resistance to fire and the pumice aggregate which is at the beginning of these materials is sufficient in our country and also the use of pumice in the production of lightweight concrete constitutes the most important point of today's work. The purpose of this study is to investigate the usability of lightweight concrete, obtained by using pumice aggregate as a screed and a maximum particle diameter of 1 mm, to be produced for a construction material that provides economical and sufficient conditions. The amount of material required for concrete mix is used as weight. The total volume of the mixtures was determined by finding the volume of material in each group. Light concrete was prepared with 250 kg/m3 and 350 kg/m3 dosages. In addition, light concrete blocks were produced by adding lime to the mixtures at 0.20, 0.40 and 0.60 percent of cement. These produced lightweight concrete blocks were water cured. Unit volume weight, water absorption, porosity, compressive strength, freeze thaw resistance and thermal conductivity values of the samples were determined. When the results are examined, it was determined that unit volume weight values changed between 1.338 t/m3 and 1.471 t/m3, water absorption porosity values changed by about 14±2%, and porosities were changed to about 21±1%. it has been observed that the compressive strength decreases with increasing lime ratio between 10 MPa and 2.2 MPa and the freezing and thawing strengths are improved positively. The thermal conductivity values of the lightweight concrete … |
