MACRO 54MM

WHAT IS MACRO 54MM?

  • It can be used as primary reinforcement in concrete,
  • High strength, polymer based,
  • It provides crack resistance and load bearing with two different materials in its composition,
  • It is a long-lasting, Synthetic Macro Fiber Reinforcement.
  • Macro 54 mm is homogeneously dispersed in the concrete, providing the desired concrete appearance and strength with minimum labor and cost during and after pouring, and offers ease of application to projects.

It contains;

  • Thanks to the single fiber copolymer structure it contains, it prevents load transfer and crack formation arising from internal stresses, and increases tensile strength in bending and splitting.
  • In addition to the copolymer structure, shrinkage and heat-related cracks are prevented thanks to the polypropylene fibers in the mixture at a special rate.

DOSAGE and USE

Macro 54 mm has dosages varying between 1-10kg/m3 in different applications. In average ground conditions, Macro 54 mm is used in the dosage range of 2-4 kg/m3 under average loads of shotcrete and ground concrete.

For a homogeneous mixture, it is sufficient to add Macro 54 mm to the concrete mixture by putting it on the aggregate band in the concrete plant.

If it is desired to be mixed at the construction site, it is recommended to add it to the transmixer at the specified dosage and mix for a minimum of 5 minutes. After this period, a homogeneous mixture is obtained and applied to the field without the need for any operation other than the standard concrete casting application.

TECHNICAL ADVANTAGES
  • It prevents shrinkage cracks and microcracks.
  • It has high energy absorption capacity.
  • It increases the fatigue resistance and ductility of concrete.
  • It reduces surface wear.
  • Increases impact resistance.
  • It provides high bending and splitting tensile strength.
  • It works in 3 dimensions, undertakes the task of pressure reinforcement against negative moments on the surface.
  • It increases durability by not being corroded.
  • It gives extra resistance to the concrete weakened by freezing and thawing.
  • It ensures that the concrete, which decomposes in acidic and salty environments, stays together.
  • Increases fire resistance.
  • It provides the concrete to gain elastoplastic behavior.
  • It has a high brittleness rate.
  • Thanks to its fringed structure, it has a superior adherence ability than other fibers.
COST AND APPLICATION ADVANTAGES
  • It provides an advantage in terms of workmanship during application.
  • Time loss during the assembly of the steel mesh is not experienced with Macro 54 mm.
  • The purchasing cost is more advantageous than steel mesh and steel wire.
  • Since rust is not used, the floor thickness is reduced.
  • Non-corrosion extends service life and maintenance periods.
  • It is not damaged during stocking and can be stored for a long time.

MACRO 54 MM PROVIDES RESISTANCE TO RESTORATION CRACKS

One of the most negative factors that reduces the strength of concrete is shrinkage. Shrinkage, which means the shrinkage of concrete, brings with it superficial or deep cracks in the concrete. Expansion or contraction, swelling, creep and shrinkage caused by thermal effects are the main events that cause early volume changes in concrete.

MACRO 54MM

  • It creates resistance to shrinkage stresses.
  • It minimizes the amount of cracks formed due to shrinkage.
  • It is homogeneously dispersed in the concrete and adheres to the concrete very strongly.
  • It confronts the crack at the first moment and prevents the crack from progressing.

TENSILE TESTS IN BENDING AND SPLITTING
ISTANBUL TECHNICAL UNIVERSITY BUILDING MATERIAL LABORATORY

Concrete prism samples of 150x150x600 mm, belonging to C30 concrete class, containing Macro 54 mm brand, copolymer/polypropylene carrier synthetic fiber (54 mm long) and steel wire from another company (60 mm length, 0.75 mm diameter, hook tip) were produced. In addition, 150x150x150 mm cube samples were produced to determine the split-tensile strengths. In order to compare the performance criteria of these concretes produced using copolymer/polypropylene carrier synthetic fiber and steel wire, witness samples belonging to the same concrete class were produced and bending and splitting-tensile tests were carried out. Obtained results are given below.

PRISM EXPERIMENTS

Closed-loop deformation-controlled one-third load bending tests were conducted on concrete prisms produced using compositions with constant cement content, water/cement ratio and workability (10-12 cm slump). The definition of the samples, the experimental setup and the results obtained are given below.

Test Samples

Each sample is prism-shaped, measuring 150x150x600 mm.

The experimental setup

The experimental setup of the samples placed in such a way that the distance between the supports is 450 mm is given in the figure.
