Principle types of
reinforced concrete with efficient use
of mill-cut steel fibre:
Name of CR-structures |
Expected effectiveness of steel-fibre reinforced concrete (SFRC) |
| Concrete slabs of roads and airport pavements | Slabs’ durability increase; partial or complete refusal of steel mesh fabric and rods; possible reduction of slab thickness |
| Blocks of bank protection walls | Durability increase up to 2-3 times. |
| Piles, prismatic and pyramidal, up to 14 m in length (head and peak), entirely from SFRC. |
Increase of impact strength, insuring of absence of defects at immersion; reduction of immersion time due to heavy hammers. |
| Slabs of railroad crossings | Durability increase up to 2-3 times; partial refusal of steel rods. |
| SFRC-rings of control wells for water-supply and sewerage. | Reduction of ring thickness; refusal of steel rods. |
| Prefabricated RC-prestressed slabs (6x6 or 6x15 m) for industrial building covering. | Increase of crack resistance; refusal of transversal reinforcement. |
| Drain-chutes from SFRC | Reduction of chute thickness; refusal of steel rods. |
| Contact-line supports with increased longitudinal crack-resistance. | Supports’ durability increase. |
| Nonpressure and low-head pipes | Refusal of ring reinforcement; crack-resistance and strength increase. |
Wide use of steel-fibre-concrete in construction allows getting more qualitative durable structures!
