Özet

In this study, reaktive powder concrete (RPC) samples obtained from ground zeolite mixed with cement, gypsum and lime were produced by using a press compacting processes and steam-curing. The compressive strength, density and water absorption properties of the samples were determined. According to experimental results, while dry unit weight is varied between 1477 and 1677 kg m(-3), compressive strength of 28 days specimens ranged from 7.3 to 25.3 MPa and water absorption changed approximately between 19% and 9%. Building materials produced from addition of low-rate cement, gypsum and lime to ground zeolite using the pressure method had generally better physical and mechanical properties as compared to the traditional building materials.
