Definitions
- the total dose of basalt aggregate is in the range of 1500 to 2000 kg/m 3 and ratio of sieve sizes is determined by granulometry and mineralogical composition of particular source of basalt aggregate.
- the first type of fibres has rectangle cross-section; width of the cross section ranges between 0.2 and 0.5 mm, cross sectional height ranges between 1.5 and 2.0 mm and length of fibres ranges between 25 and 35 mm.
- Strength of the first type of fibres is 350 - 450 MPa.
- the second type of steel fibres has circle cross-section with diameter ranging between 0.08 and 0.12 m; their length is between 8 and 15 mm and their strength is higher than 2000 MPa.
- the weight of both types of fibres together ranges between 100 and 280 kg/m 3 .
- Ratio of the first and second type of fibres is expediential between 0.5/1.5 and 1.5/0.5.
- the use of fibres from industrial waste is very advantageous.
- the first type of fibres is profitably made from waste steel strip and the second type is made from cut cord fibres gained in recycling of tires.
- the amount of admixtures varies between 5 and 15% of steel fibre reinforced concrete volume.
- New solution consists in design of structure of cement composite, namely steel fibre reinforced concrete, where two different types of steel fibres are utilised.
- the importance of the new solution significantly increases if the steel fibres are gained entirely from waste.
- the result of utilisation of dispersed fibre of two different types is both strengthening of the steel fibre reinforced structure and providing of uniform distribution of coarse aggregate.
- the necessary condition for the design of the steel fibre reinforced concrete composition is utilisation of basalt aggregate with common grain size distribution 0-4, 4-8, 8-16. Weight ratio of coarse sizes depends on required characteristics of hardened concrete.
- Design of the steel fibre reinforced concrete composition is performed according to requirements on strength in compression, eventually tensile strength.
- the dosage of aggregate ranges between 1500 - 2000 kg/m 3 depending on used weight batches of steel fibres.
- Total weight of both types of fibres ranges between 100 - 280 kg/m 3 .
- Steel fibres of the first type have rectangular cross-section 0.2- 0.5 mm / 1.5-2 mm, length of 25-30 mm and strength of 350-450 MPa; they are made from waste steel ribbons.
- Steel fibres of the second type have circular cross- section with diameter of 0.08-0.12 mm, length of 8-15 mm and their strength is higher than 2000 MPa.
- the second type of fibres is advantageously gained during recycling of tires.
- the weight ratio of listed types of steel fibres is within the limits of 0.5:1.5 and 1.5:0.5; generally 1 : 1 ; the steel fibres are always evenly distributed in the hardened concrete.
- Cement, admixtures and additives are dosed with the aim to reach dense structure of the steel fibre reinforced concrete.
- the dense structure is the carrier of ultra-high strengths and provides suitable workability of the fresh steel fibre reinforced concrete by common compaction tools.
- Basalt aggregate is composed from three sieve sizes, namely 0-4, 4-8 and 8-16, in the weight dose between 1500 and 2000 kg/m 3 .
- the ratio of the sieve sizes is determined according to the demands of compressive strength of hardened steel fibre reinforced concrete. Water / cement ratio ranges between 0.16 and 0.25. Examples of composition of the steel fibre reinforced concrete, including recorded average strengths in compression and tensile splitting strength are listed in the table bellow. 1. example of high-performance concrete mix proportions:
- the resulting compressive strength significantly exceeds the value of 60 MPa, which is the minimal limit for high-strength steel fibre reinforced concrete; that is why this material can be called high-strength one. Both strengths exceed common concrete strengths approximately six times; this implies utilisation of the material in extremely loaded elements such as columns of high-rise buildings, bridge piers and bridge decks.
- Resulting compressive strength exceeds the value of 150 MPa, which is minimal limit for Ultra-high strength steel fibre reinforced concrete, that's why the material can be called ultra-high-strength.
- This material is intended due to its properties for utilisation in extremely compressed elements or extremely slender elements, that may be required in designing of the entity. Composition of the material makes it resistant to freeze-and-thaw cycles and climate strains.
