Investigation into the Possibility of Reactive Powder Concrete Production Using Available Materials in Iran

Reactive powder concrete (RPC), as a new type of ultra-high-performance concrete, has attracted a lot of attention in recent years. This type of concrete with a compressive strength of more than 150 MPa, has high packing density, very low permeability, superior durability and very high abrasion and corrosion resistance. Small steel fibers, used in RPC, cause the increase of flexural strength and ductility. In the present study, it has been tried to produce reactive powder concrete using the most suitable available materials in Iran. Also, the effects of different curing methods on the properties of RPC have been investigated. The results show that using the available materials together with steel fibers and conducting heat treatment, reactive powder concrete with compressive strength up to 160 MPa and flexural strength of 25 MPa was produced.
