High-performance concrete is a very popular construction material used in recent years. The compressive strength and flexure of (HPC) reinforced with basalt fiber (BF) were investigated. influence six different fraction which includes (0%, 0.6%, 0.9%, 1.2%, 1.5%, 1.8%) on the flexural examined. experiment local materials commonly industry Moscow. performance under distribution stress presented....

Abstract In order to study the effect of basalt fiber content, length and coal gangue activation on compressive strength splitting tensile concrete, 24 groups orthogonal experiments were designed. The results show that influence various factors concrete is > content length. conducive increase strength; increases first then decreases; beneficial unfavorable best ratio engineering practice 0.1...

The effects of basalt fiber incorporation on the mechanical properties red clay soils were investigated. Through direct shear test, unconfined compressive strength and microstructure curves stress–strain fiber-modified obtained under different rates soil dry density conditions. results showed that: (1) significantly increased after fiber; (2) increase was greatest at 0.3% incorporation, which o...

Currently, less than 15% of waste iron tailings are utilized. Iron can be used as fine aggregate in concrete, but this kind concrete has no coarse aggregate, resulting low strength. Additionally, contain some heavy metals, which will cause environmental pollution if improperly treated. In study, the mechanical properties, sulfate resistance, and pore structure distribution basalt fiber-biochar-...

The question of increasing the reliability and durability reinforced concrete structures is a priority. One ways to increase strength using dispersed reinforcement. interest fiber-reinforced in Russia, as well Europe, Asia USA has increased significantly recent ten years. improvement physical mechanical properties noted depend on reinforcement parameters, such volume content fiber, characterist...

The development of recycled aggregate concrete (RAC) provides a new approach to limiting the waste natural resources. In present study, mechanical properties and deformability RACs were improved by adding basalt fibers (BFs) using external restraints, such as fiber-reinforced polymer (FRP) jacket or PVC pipe. Samples tested under axial compression. results showed that RAC (50% replacement aggre...
