چکیده
Abstract High-strength concrete incorporating macro-fiber combines high compressive strength of the matrix, strain-hardening, and multiple crack characteristics. Also, calcite sediment remediation bacterial techniques can enhance mechanical properties, reduce deterioration, prevent corrosion steel reinforcement in both short-term long-term. In this paper, The Bacillus subtilis bacteria at an optimum dosage 105 cells/ml mixing water was incorporated into M60 M80 strengthened with 0.5% macro synthetic-fiber content. performance 32 simply supported reinforced beams rectangular-section were evaluated numerically using ANSYS. study, properties matrix components are considered for different geometric sizes as slender short longitudinal ratios. results showed that participation fibrous had more significant enhancement initial cracking load, ultimate moment capacity ratio, ductility flexural toughness compared to associated conventional concrete.

Mechanical Behavior of Hybrid Fiber Reinforced High Strength Concrete with Graded Fibers
Brittleness, which was the inherent weakness in High Strength Concrete (HSC), can be avoided by reinforcing the concrete with discontinuous fibers. Reinforcing HSC with more than one fiber is advantageous in an overall improvement of the mechanical performance of the composite. In this experimental study, Hybrid Fiber Reinforced High Strength Concrete (HyFR-HSC) mixes were formed by blending si...

Abstract Concrete is an indisputable material for the construction of various types of structures in the modern advancement of civil infrastructures. Concrete is strong in compression but weak in tension and shear. To eliminate those problems, the introduction of fiber was brought in as an alternative to developing concrete in view of enhancing its tensile and shears strength as well as improvi...
