Abstract Ten concrete mixtures, using long and medium length hooked-end short wave-shaped steel fibers, were designed to experimentally investigate the effect of hybrid reinforcement on workability, drying shrinkage, mechanical properties fiber reinforced concrete. The fibers reduced workability shrinkage. Hybrid including fiber, can produce a synergistic compressive strength. For adopted mater...

-Concrete has been widely used as a construction material in Buildings and other Industrial Structures. Sufficient research work has been carried out to understand the Mechanical properties like Compressive Strength, Flexural Strength, Tensile strength, Shear strength and Modulus of elasticity. There are many situations in which the concrete undergoes variation in temperatures which will ultima...

Research & Development in Material Science Delayed Bleeding of High-Strength Steel Fiber Reinforced Concrete Mix Dorf VA, Turkin VV* JSC “Institute “Orgenergostroy, Moscow, Russia *Corresponding author: VV, Submission: July 26, 2022;Published: August 05, 2022 DOI: 10.31031/RDMS.2022.17.000915 ISSN: 2576-8840 Volume 17 Issue 3

The article presents the results of research on modified steel fiber-reinforced concrete and shows expediency their use to increase effectiveness fortification protection structures against shock loads. It was established that according tests compressive strength (fсm = 79.4 MPa) tensile during bending (fс, lf 7.4 MPa), can be classified as high-strength (strength class C 50/60) rapid-hardening...
