Investigation of the effect of press compaction and the use of zeolite on mechanical properties in the production of low strength Reactive Powder Concrete (RPC)

Abstract

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.
