Experimental investigation of the strength of glass fiber-reinforced concrete exposed to high temperature
This study investigated the effects of high temperature exposure on the compressive, tensile, and flexural strengths of concrete containing glass fiber. A total of 108 cubic specimens (150 mm × 150 mm × 150 mm), cylindrical specimens (300 mm × 150 mm), and prismatic specimens (500 mm × 150 mm × 150 mm) were prepared for compressive, tensile, and flexural strength testing, respectively. The spec...
متن کاملMechanical 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...
متن کاملFeasibility of Reducing the Fiber Content in Ultra-High-Performance Fiber-Reinforced Concrete under Flexure
In this study, the flexural behavior of ultra-high-performance fiber-reinforced concrete (UHPFRC) is examined as a function of fiber length and volume fraction. Straight steel fiber with three different lengths (lf) of 13, 19.5, and 30 mm and four different volume fractions (vf) of 0.5%, 1.0%, 1.5%, and 2.0% are considered. Test results show that post-cracking flexural properties of UHPFRC, suc...
متن کاملModeling for the Evaluation of Strength and Toughness of High-performance Fiber Reinforced Concrete
This paper presents the multivariate linear models for the evaluation of compressive, flexural and splitting tensile strengths, and toughness ratio of high-performance steel fiber reinforced concrete (HPSFRC). In this study, 44 series of concrete mixes with varying silica fume replacement and fiber dosage (Vf = 0.0, 0.5, 1.0 and 1.5%) were considered. Test results indicated that addition of fib...
متن کاملMicroplane Model M6f for Fiber Reinforced Concrete
The new microplane model M6f for fiber reinforced concrete features several improvements over the earlier versions: (i) An explicit volumetric-deviatoric split to no split transition formulation in tension which eliminates spurious contraction under tension that the earlier models suffered; (ii) tension-compression load cycles are now correctly simulated using the loading/unloading rules prescr...
