A-Train FF
JUMP TO
GENERAL DESCRIPTION
A-Train FF is a specialty solution of selected surfactants for use as an Admixture for Cellular and Pre-Foamed Lightweight Concrete and for use as a Synthetic Air Entraining Admixture for Concrete. When used with a Foam Generator and a suitable water supply, A-Train FF produces a consistent pre-foam that is stable under alkaline conditions and suitable for use in the production of foamed concrete. Foamed concrete is the industry term used for the product produced by the controlled addition of a pre-foam to a cement grout or sand/cement mortar. A range of densities can be produced, typically from 20 to 100 lb/ft³. Foamed concrete is lightweight and highly mobile, able to flow for long distances under its own hydraulic head, and is an ideal material for uses such as void filling, roof screeds and trench reinstatement.

- Cellular grout
APPLICATIONS & BENEFITS
APPLICATIONS
APPLICATIONS & BENEFITSTypical applications for foamed concrete include but are not limited to:
- Controlled low strength materials
- Trench filling for permanent, non-sink reinstatement
- Elimination of fire risks, health hazards and control of progressive collapse in areas such as underground fuel tanks, below railway platforms, old mine workings, sinkholes, industrial remediation, nuclear decommissioning and abandoned sewers
- As a lightweight thermal insulating material for roof screeds, suspended floors and basements
- As a semi-structural support in embankments, bridge abutments, tunnels and arches
FEATURES & ADVANTAGES
APPLICATIONS & BENEFITS- Produces a consistent, stable pre-foam when used with a Foam Generator
- Easily controlled addition of pre-foam to pre-batched mortar allows close control of finished density
- Expensive blending equipment is not required as mixing can be carried outin the drum of a ready mix truck
- Produces a highly mobile foamed concrete which is easily placed withoutcompaction
- Foamed concrete retains its volume and does not sink during or afterhardening
Recommendations
APPLICATIONS & BENEFITS
The dosage depends on the original starting materials and the desired final density of the foamed concrete. Typical dosages are in the range of 16 to 64 ounces per cubic yard of finished foamed concrete over a density range of 20 to 100 lb/ft³. The optimum dosage of A-Train FF to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. Dosages outside the typical range suggested on this data sheet may be used if necessary and suitable to meet particular mix requirements. Contact your local Riteks technical service representative for advice in these cases.

Compatability
A-Train FF is compatible with all types of Portland cement, class C and F fly ash, silica fume, calcium chloride, fibers and approved air entraining, accelerating, retarding, superplasticizing, and water-reducing admixtures. A-Train FF can be used in white, colored, and architectural concrete. For best results, each admixture must be dispensed separately into the concrete mix.
Limitations
Trials should be made using relevant materials and conditions in order to determine the optimum mix design and admixture dosage to meet specific requirements. Compressive strength is proportional to its density and also to the cement content of the original mortar. A number of factors, such as water to cement ratio and the materials used, can affect the unit weight and compressive strength. A-Train FF is not intended for direct addition to the mortar and use in this manner will not produce foamed systems. A-Train FF may not be suitable for use with certain sands, in particular coarse sands. Sands containing a significant amount of particles greater than a #16 sieve should be avoided. Pre-foam should not be made using concrete wash water or water from other sources containing high levels of calcium ions.
