This research studied the influence of three types open (short-straight, long-straight, semicircular) and different shapes closed steel fibers (triangular, rectangular, circular) with fiber contents by volume (0, 0.5%, 1%, 1.5%, 2%) on working mechanical performance reactive powder concrete (RPC). The results indicated that (1) number enclosed area formed would remarkably impact RPC; (2) semici...

High strength concrete is seldom used in normal construction practice due to its high cost and difficulties achieving the desired design strength. This paper gives an insight on using waste material which has been disposed lands as a sustainable replace sand achieve The compressive of Reactive powder (RPC) produced this work was 88 MPa flexural 20 MPa. Also influence different curing methods pr...
