R&D department of AGRESTA developed concrete formulas with wood aggregate AGRESLITH-C® and cement, which are optimized for construction, renovation and interior design.


Properties :

Lightweight concrete with wood aggregates Lightweight:Up to 5 times lighter than conventional concrete. Density of concrete (500 kg/m3 to 1200 kg/m3) depends on resistance requirements and the structural load of construction.
Thermal insulation by concrete with wood aggregates
Thermal Insulation: Concrete with wood aggregates differs from traditional insulation because it combines its low thermal conductivity coefficient with a high thermal inertia.
Sound insulation - concrete with wood chips.
Sound Insulation: Concrete with AGRESLITH-C® offers new standards. According to our experiments, AGRESLITH-C® limits noise pollution (10 cm concrete with AGRESLITH-C® isolate max. 55 dB).
concrete with wood chips - fire resistance. Fire Resistance: Concrete with AGRESLITH-C® is nonflammable; classified M1. Moreover concrete which includes high volume of wood will not generate chemical smokes.
Concrete with wood aggregate is sawable, screwable. Sawable & Screwable & Nailable: Concrete with AGRESLITH-C® allows the installation of screws and nails without using drill or rawlplug.
Wood aggregate for concrete - mechanical performance Mechanical Performance : Tensile strength in bending (3MPa) and compressive strength (6.6 MPa).

Application Areas :

  • Screed implementation in all types of rooms and on any types of support.

  • Minimum thickness of screed should be 6 cm. Screed with AGRESLITH-C® is suitable for all types of flooring (stone, parquet, laminate, vinyl or carpet flooring).

Advantages :

Use of wood aggregates instead of gravel in a concrete mix provides several advantages :

  • Helps in the construction of energy-efficient buildings.
  • Important savings in dead load by using wood aggregates concrete as a floor fill.
  • Maximizes transport capacity.
  • Speeds up completion period of a construction.
  • Wood is the only renewable material between all other options.
  • Stocks 350Kg of CO2/m3, the slab will contain 95% of wood chips after it has dried.


Designers, builders and owners must become aware of the energy saving potential of lightweight concrete used as insulating fill for floors and roofs:

  • Enhances sustainability.
  • Minimizes heat loss.
  • Prevents moisture condensation.
  • Increases year-round comfort.

Dosage & Implementation

Dosages for different formulas :


Formula 500 Kg/m3 - Level adjustment


Formula 650 Kg/m3 - Natural lime based


Formula 800 Kg/m3 - Standard formula / Renovation


Formula 1200 Kg/m3 - Floor heating system


Instructions for mixing in a concrete mixer :


1)
Put water, sand and cement into the mixer according to the suitable formula.

2) Mix until these elements are homogeneous.

3) Gradually add polypropylene fibers.

4) Gradually add wood chips.

5) Mix in slow rotation.

6) Mixture is ready when aggregates and fibers are uniformly covered with cement.


Instructions for screed implementation :


PRECAUTIONS BEFORE POURING

- Do not pour below 5°C.

- Cover the surface with polyethylene or breathable film (depending on support).

- Ensure that film covers corners efficiently.

- Leave at least 30 cm film in vertical ascent.

- Set up joints (expansion and contraction joints, fractionation and separation devices, etc.).

- Wire mesh panel is unnecessary if polypropylene fibers were added to the mixture.


POURING AND PLACING CONCRETE

1) Pour concrete mix onto your surface.

2) Compact slightly. Compaction must be uniform over the entire surface.

3) Ensure that edges and corners are properly filled.

4) Level the concrete across the entire top surface with a trowel or a smooth flat tool.

5) Optionally spread cement and sand onto the surface to fill cavities.

6) Cover the screed with a polyethylene film for 5 days, then remove it and ventilate the surface.


PRECAUTIONS DURING DRYING

- Do not operate on the slab during curing phase.

- Protect surface from sunlight, air currents and rain.

- Set up control joints 24 - 48 hours after pouring (if has not done before).
