Shrinkage of High Strength Concrete
This paper presents the results of an experimental investigation carried out to evaluate the shrinkage of High Strength Concrete. High Strength Concrete is made by partially replacement of cement by flyash and silica fume. The shrinkage of High Strength Concrete has been studied using the different types of coarse and fine aggregates i.e. Sandstone and Granite of 12.5 mm size and Yamuna and Bad...
متن کاملExperimental 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 کاملAxial Compressive Strength of Reinforced Concrete Columns Wrapped with Fiber Reinforced Polymers (FRP)
This paper presents the results of a study on the axial compressive strength of columnsstrengthened with FRP wrap. The experimental part of the study included testing 6 reinforcedconcrete columns in two series. The first series comprised three similar circular reinforced concretecolumns strengthened with FRP wrap. The second series consisted of three similar square columns,two with sharp corner...
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...
