PolyЯRon LWC is an effective foaming agent to produce light weight concrete used as insulation system in construction industry. PolyЯRon LWC is a concentrated solution of selected surfactants. When used with a Foam Generator and a suitable water supply, PolyЯRon LWC 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. 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, trench reinstatement and also for insulation

Advantages

• 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 out in the drum of a ready mix truck.
• Produces a highly mobile foamed concrete which is easily placed without compaction.
• Foamed concrete retains its volume and does not sink during or after harden.

Application area

Typical applications for foamed/Light weight 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 arche.

Applicable standards

PolyЯRon LWC complies with ASTM C-796

Dosage

The dosage of PolyЯRon LWC will vary depending on many factors including mix design, type of foam generator, mortar density etc. PolyЯRon LWC diluted with water at a ratio of 1:14 by volume shall be used for foam generation using a suitable foam generator. A typical mix is as follows.
