Fluid CR

The addition of the Fluid CR additive allows the improvement of various characteristics of the conglomerates, both in the fresh state and in the hardened state.
In the fresh state:

• drastically reduces the water/cement ratio;
• makes the mixture anti-washout therefore advisable, often indispensable, in castings in the presence of water (both fresh water and sea water) inside the formwork;
• avoids segregation and bleeding phenomena (separation of the mixing water);
• improves the workability of the casting, both in plastic and fluid consistencies, reaching self-compacting workability;

In the hardened state:

• increases mechanical performance in compression, bending, traction, abrasion;
• it drastically reduces porosity, increasing the compactness of the casting and waterproofing, resulting in the creation, with appropriate mix designs, of intrinsically waterproof concrete;
• increases the chemical-physical resistance and consequently the durability of the conglomerate;
• the slightly expansive characteristics, induced in the conglomerates by the special additives contained in the formulation, allow the drastic reduction of shrinkage phenomena and pre-compression of the reinforcing bars.

Fluid CR is perfectly compatible and synergistic with all our metallic and/or synthetic fibers from the READYMESH line. The introduction of Fluid CR in fibre-reinforced conglomerates increases the meshing between fiber and matrix, enhancing the mechanical performances induced by the fibrous components. Fluid CR is perfectly compatible and can be used with all types of Portland, Pozzolanic, Blast Furnace or Composite cement available on the market.

• Expansion prevented with dosages > 30 kg/m3 (UNI 8147): > 0.01%
• Increase in mechanical resistance: 10-30%

Fluid CR must be added to the anhydrous components of the conglomerate (binders and aggregates), together with the mixing water. In concrete mixing plants, it is recommended to introduce the additive after or together with the insertion of the aggregates and before the introduction of the cement. After adding the product, ensure adequate mixing in order to obtain a homogeneous mixture free of lumps. Adjust the mixing water according to the effect of reducing the w/c ratio induced by the formulation. As regards setting times, Fluid CR is considered a neutral additive, i.e. it does not involve changes in the normal setting and hardening times of the cement conglomerate in which it is inserted.
