The Chloride Ion Penetration Mechanism in Basalt Fiber Reinforced Concrete under Compression after Elevated Temperatures

Basic Mechanical Properties of Basalt Fiber Reinforced Recycled Aggregate Concrete

In order to study the basic mechanical properties of basalt fiber reinforced recycled aggregate concrete, the concrete mix ratio, the length and the volume mixing ratio of chopped basalt fiber yarn are designed for changing factors. A total of 324 specimens have been completed for this investigation. The compressive strength, splitting tensile strength, elastic modulus and axial compressive str...

Research on Chloride Penetration Resistance of Hybrid Fiber Reinforced Self-Compacting Concrete

The properties of chloride penetration of hybrid fiber reinforced self-compacting concrete (SCC) were investigated in this study. The results show that the chloride penetration resistance of concrete can be improved by single incorporation either carbon or cellulose fibers. The concrete chloride diffusion coefficient DRCM of 12-cm length carbon SCC with fiber content of 1.7, 2.72, and 3.4 kg/m3...

Flow of Fiber-Reinforced Cement Slurries at Elevated Temperatures

Cement slurries are used for the construction of oil wells as deep as 30,000 ft (9,000 m). The severe performance requirements for such materials have prompted the search for appropriate fiber reinforcement to improve the slurry’s tensile strength, impact resistance, and fracture toughness, without decreasing its pumpability. A continuum theory for dilute suspensions of large-aspect-ratio parti...

Experimental Investigation on the Static and Impact Behaviors of Basalt Fiber-Reinforced Concrete

Experimental studies on basalt fiber have been performed in China and abroad. Specifically, the compressive properties, flexural properties, splitting tensile properties and impact test behavior of chopped basalt fiber-reinforced concrete have been investigated. In addition, the effects of the mixing amount of fibers on the mechanical properties of C30 concrete were scrutinized, and the best mi...
