CONCRETE MIX DESIGNS USING A PLURALITY OF REINFORCEMENT FIBERS SYSTEMS.

摘要

A concrete mix comprising sand, fine aggregates, binder, fibers, and various admixtures, having a consistency from S2 to SF3, a compressive strength in the range of 30-80 MPa and a ductility represented by fc, ffl, f R1 and f R3 values, wherein the concrete mix contains at least 390 Kg of binder, the concrete mix comprises a paste volume of 300- 600 liters, the concrete mix contains at least two systems of metallic fibers and a general admixture system that is composed of at least 2 sub-admixture systems.
