Effect of Hybrid Fibers on the Mechanical Properties of High Strength Concrete

Tikrit Journal of Engineering Sciences, 2013
In this study, high strength concrete of 75 MPa compressive strength was investigated. The experimental program was designed to study the effect of fibers and hybrid fibers (steel and polypropylene fibers) on the fresh (workability and wet density) and ...

The effects of steel fiber waste tyre on properties of high strength fly ash concrete [PDF]

MATEC Web of Conferences, 2019
The utilization of steel fiber from waste tyres can be an alternative to reduce waste tyres due to the increase of tyre production in Indonesia annually. Steel fiber from waste tyre can be added to concrete mix to improve the concrete properties. In this

Shear capacity of high-strength concrete beams with their point of inflection within the shear span [PDF]

, 1998
The shear strength of concrete does not increase in proportion with the concrete grade. Thus, when high-strength concrete is used in place of normal-strength concrete, the shear capacity of the structure could become critical. In the study presented, the

Effects of High-Strength Concrete on Progressive Collapse Resistance of Reinforced Concrete Frame

, 2020
The application of extreme loads, such as impact and blast, may lead to progressive collapse and the robustness of a structure must be considered in this context.

Enhancing Structural Resilience: Microbial-Based Self-Healing in High-Strength Concrete

International Journal of Concrete Structures and Materials
Concrete’s weak tensile strength renders it susceptible to cracking under prolonged loads, leading to reduced load-bearing capacity and reinforcing bar corrosion.
