ROCKBOND LIGHTWEIGHT (1800) GROUT (LW1800G) powder is a premixed, ready to use, low density grout powder. The compound consists of a blend of cement powders, shrinkage compensating agents, graded lightweight aggregates, and a combination of compatible admixtures.
The powder, when mixed with water, produces a lightweight, free flowing grout which is easily mixed, pumped and placed.
The grout is specially designed to be low in weight, and to penetrate and fill large volume voids that require a low density material.
The grout powder is packed in 25kg moisture proof, durable bags and has a shelf life of 2 years.
Premixed and ready to use.
Quickly and easily mixed with water.
Can be designed and supplied to produce a density of between 750 to 1800kg/m3.
Portland cement based, shrinkage compensated, microsilica enhanced.
The grout will not segregate or bleed, is readily pumpable and self compacting.
Excellent insulator, and a poor conductor of heat and sound.
Resistant to fire, non flammable and will not give off toxic gases.
Contains no chlorides, high alumina cement or deleterious substances.
High yielding and economical to use.
High yielding, economical, non flammable, non toxic, odour free, user friendly and safe to use.

Whenever a low weight, high flow material is required.
For the installation of lightweight concrete structures.
Compatible repairs to lightweight cementitious materials, concrete, bricks and blocks.
For use as a large, lightweight volume void filler.
To form and manufacture low density, precast concrete products and lightweight artefacts.
To fill areas that require a low heat material.
To protect steel and concrete structures from fire and heat.
To thermally insulate buildings and walls on the inside or outside.
As an insulating infill around pipes and ducts.
To minimise condensation on walls and ceilings.
To acoustically insulate rooms or areas to reduce noise and sound.
