Abstract—Reactive Powder Concrete (RPC) is an ultra high performance concrete which has superior mechanical and physical properties. RPC is composed of cement and very fine powders such as crushed quartz (100–600 μm) and silica fume with very low water/ binder ratio (W/B) (less than 0.20) and Superplasticizer (SP). RPC has a very high compressive and tensile strength with better durability properties than current high performance concretes. Application of very low water/ binder ratio with high dosage of super plasticizer, different heat curing processes and pre-setting pressure improve mechanical and physical properties of RPC. In this study, RPC is composed of available materials in Iran. Two different mixing proportions were used in laboratory and samples were prepared in different water/ binder ratios and superplasticizer dosage under 0, 25, 50, 100 and150 MPa pre-setting pressure, and then 7 different curing regimes were applied to the specimens. It was observed that higher temperature and pre-setting pressure increase the compressive strength of the compositions.
