Macro-synthetic-fibre-reinforced concrete

Macro-synthetic-fibre-reinforced concrete. Macro synthetic fibres are typically used in structural concrete as replacement for nominal bar or fabric reinforcement; they do not replace structural steel and can not be part of the design in accordance with these Eurocodes. However, macro synthetic fibres can be used to provide the concrete with significant post-cracking capacity and hence can be ...

Influence of Steel and Macro-Synthetic Fibers on Concrete ...

Two steel (high stiffness) and two macro-synthetic (low stiffness) fibers with similar aspect ratios were adopted in two base concretes varying in both water-to-cement ratio (0.45 and 0.50) and fiber volume fraction (0%, 0.5%, 1.0%) to evaluate the influence of steel and macro-synthetic fibers on fresh concrete

New macro polymer fibers for load-bearing applications in ...

The optimized macro fiber for sprayed concrete: SikaFiber Force 60 was especially conceived for load-bearing applications using sprayed concrete. The main fields of application, for example, are sprayed concrete used as excavation protection in tunnel construction or as rock and soil stabilization. In case of sprayed concrete, with SikaFiber Force 60 the reinforcement is directly integrated in the spraying process. This reduces the effort required in comparison to conventional steel ...

Concrete Reinforcing Fibers - Sika

Structural macro fibers have a diameter greater than 0.3 mm. Macro fiber are used as a replacement for temperature and shrinkage reinforcement (WWF) or as structural reinforcement in concrete or shotcrete. Macro fibers are used where an increase in residual (post-cracking) flexural strength is required (ASTM C1609 or EN14845).

What is Macro Synthetic Fibre Concrete ... - Home - MSFA

Macro Synthetic Fibre (MSF) is modern concrete reinforcement used as crack control and structural reinforcement in concrete. Fibres have been used for thousands of years in mortar construction. With the latest manufacturing techniques, we can take modern synthetic materials and turn them into highly engineered short fibres which act like small reinforcement bars in concrete. Dependent on the ...

Steel Fibers and Rebar - Concrete Fiber Solutions

09/12/2015  Steel fibers and rebar have some things in common. Both are made of steel. Both are used to reinforce concrete, and both can be found in floor slabs. Because of those common features, it is tempting to think of the two products as fundamentally alike, differing only in size. Maybe a steel fiber is just a very small reinforcing bar. Some of our ...

Fiber Reinforced Concrete Association Fiber Types ...

Steel Fibers: These fibers are generally used for providing concrete with enhanced toughness and post-crack load carrying capacity. Typically loose or bundled, these fibers are generally made from carbon or stainless steel, and are shaped into varying geometries such as crimped, hooked-end or wit other mechanical deformations for anchorage in the concrete. Fiber types are classified within ACI ...

Influence of Steel and Macro-Synthetic Fibers on

Fiber addition has become one of the most prevalent methods for enhancing the tensile behavior of concrete. Fibers reduce cracking phenomena and improve the energy absorption capacity of the structure. On the other hand, the introduction of fibers can introduce a negative impact on concrete workability, whose loss is influenced by different parameters (among which are fiber content and fiber ...
