Fibre Conrete

Fibre-reinforced concrete

Product description

Marlon Fibre Concrete is a cement-based, fibre-reinforced dry mortar product that is ready for use. Just add water. The product contains cement, polypropylene fibre, additives and oven-dried silica sand. Marlon Fibre Concrete is contraction-compensated and consciously formulated for a dense, workable concrete. Contains no corrosive components and is water and weather-resistant in its cured state. Sand and rock materials satisfy the material requirements of environmental class E (see DS 2426).

Benefits
  • Fast-setting
  • Fibre-based
  • Contraction-compensated
  • Good workability
  • Water and frost-resistant
  • Just add water
Usage

Marlon Fibre Concrete is versatile in its potential uses, but is typically used for pouring, repairs and floor constructions, where the bearing capacity is uncertain or where strong cohering concrete with low contraction qualities is needed. Used for both indoor and outdoor repairs/work and is water and weather resistant in its cured state.

Preparation

For casting, repair work and plastering work on old concrete, the surface must be free of cement slurry, oil, grease and loose impurities. Water down the cleaned surface so it is uniform, dull and slightly absorbent, to ensure adequate adhesion of the mortar. Alternatively, Marlon Primer FL can be used, as can brush coating with Marlon Adhesion Primer CP, which ensures the greatest possible adhesion.

Mixing

Marlon Fibre Concrete is mixed in an agitator mixer for at least five minutes. Manual mixing can be done in a tub/bucket using a drill with a two-bladed propeller agitator. When mixing manually, first pour the water into the bucket, and then add the powder while mixing. Mix until you achieve a good workable and plastic consistency. Do not mix more fibre concrete than you can use within about 45 min.

Application

Pour/apply Marlon Fibre Concrete in a layer thickness of between 10 and 80 mm in a single application using straight-edge screeds, and then finish/trim. Repair and casting work is done using ordinary masonry tools. Adding more water than described will reduce the strength and increase the tendency towards contraction cracks. Higher temperatures will shorten, and lower temperatures will lengthen both the opening and hardening times.

Aftercare

The newly poured fibre concrete surface must not be exposed to loads and must be protected as quickly as possible after pouring against rapid drying from draughts, high room temperature, sun rays, etc. Use of Marlon Curing B75 or a sealing plastic is recommended.

Limitation

Unhardened concrete does not tolerate frost during hardening and setting. The temperature should remain between +5°C and +30°C throughout the hardening period.

Cleaning

Clean tools with clean water immediately after use. Cured Fibre Concrete can only be removed mechanically.

Inspection

Marlon Fibre Concrete is subject to in-house inspection according to Marlon’s quality assurance programme. Subsequent measuring and mixing at the site of application is not included in quality control.
