摘要：

Reactive powder concrete (RPC) is classified under ultra high performance concrete (UHPC) vowing to its dense and uniform microstructure and mechanical properties. The design of structures with RPC is governed by its strength and toughness characters. In the present study, RPC with compressive strength of 180 MPa and flexural strength of 25 MPa was produced using local available materials. The flexural strengths of non-fibered and fiber reinforced reactive powder concrete (FRPC) are evaluated. Toughness indices for FRPC are evaluated by load-deflection test carried on FRPC beam specimens. An analytical expression is proposed to evaluate the flexural strengths of RPC and FRPCs. FRPC beam specimens recorded higher toughness indices when compared with other class of concretes. © 2022, Associated Cement Companies Ltd. All rights reserved.
