Abstract: Based on the basic principles for producing Reactive Powder Concrete (RPC), a new kind of RPC with compositions of superfine cement, Portland cement, admixtures (ground granulated blast furnace slag and fly ash), sand, water, superplasticizer, steel fibers, without silica fume was produced and tested. Experiment results show that it is feasible to produce RPC without the admixture of silica fume. The strength, fluidity and cost of RPC are satisfied with appropriate proportion of superfine cement and admixtures. The superfine cement in RPC can be partly replaced by Portland cement to reduce the cost. The effect of the amount of steel fibers on the mechanical properties, such as compression resistance, breaking resistance, fluidity and flexural toughness, of the RPC was analyzed.

Key words: architecture material, reactive powder concrete, mix proportions, superfine cement, admixtures, mechanical properties
