| Popis: | The objective of this study has been to investigate the effect partial percentages of Scoria on Self-Compacting Concrete (SCC) in order to evaluate thermal conductivity in the Jordan building construction. The mechanical properties slump flow test, the compressive strength, the thermal conductivity (k-value) values, and the expected model for energy performance have been assessed. The slump flow test has revealed that the workability of fresh concrete has increased with increased partial replacement of scoria and vice versa. The compressive strength result has indicated that the maximum compressive strength obtained at 25% replacement has been 49.78 MPa. The thermal conductivity (k-value) result has showed that inversely proportional to the connection between scoria ratio and concrete thermal conductivity, indicating increases an insulating effect by reducing the thermal conductivity from 6.2 to 3.3 W/m K. as well as influence of scoria in the SCC is a suitable option for energy performance in the construction of buildings. |
