Easiflow CS Grout

Easiflow CS Grout is a Portland cement based product giving high strength, good flow and non-shrink properties. Placed grout gives structural support and good vibration resistance.

Easiflow CS Grout is chloride free and can be safetly used in contact with steel. The specialised mix design enables placement at low water content leading to good freeze-thaw stability, low water absorption plus resistance to oil, sea water and mild alkali
attack.

Placement thickness may be in the nominal range of 10mm to 100mm. For thicker sections 6mm Aggregate should be added at a rate of up to one to one Aggregate to Easiflow CS Grout.

Typical Uses

Crane rail tracks, stanchion bases, machine bed plates, dowel bars between pre-cast units, cable ducts, ground anchors.

Suitable Substrates

Easiflow CS Grout is suitable for masonry, concrete, brickwork, stonework and rock.

Colour

Easiflow CS Grout is grey in colour.

Packaging

Easiflow CS Grout is pre-packed in 25kg units.

Specification Outline

Grouting shall be carried out using Easiflow CS Grout. The product must be stored, handled and placed in accordance with the manufacturer’s
instructions.

Standards

Easiflow CS Grout has been tested in accordance with the appropriate parts of the following standards: EN 12390, BS 476, ASTM C953, ASTM C1107.

Easiflow CS Grout complies with the requirements of Corps of Engineers Specification for Non Shrink Grout CRD C621 and for Highways clause 2601.

Easiflow CS Grout complies with BS 6920 for water regulation WRAS (report no M103248).

Preparation

Formwork should be erected and made grout-tight. The formwork must be designed with sufficient hydrostatic head to ensure grout flow into and across the grouting area. Saturate the grouting area with water. Leave for 1 hour and then blow out any surplus water.

Shelf Life and Storage

Polycote Easiflow CS Grout has a shelf life of up to 12 months in unopened bags when kept in dry conditions at a temperature between 5°C and 45°C. Storage at higher temperatures or high humidity may reduce the shelf life.

Cleaning

Equipment should be cleaned with Solvent prior to grout hardening.

Mixing

Pour 4.5 litres of clean water into the mixing vessel for each complete bag of Easiflow CS Grout to be used. Slowly add the powder to the water whilst continually mixing.

Mechanical mixing should be carried out using either a high torque slow speed drill with a Grout Stirrer or a grout mixer
set on slow speed. (High speed or colloidal mixing will cause thixotropy leading to loss of flow.)

Curing

Placed grout, which is exposed, should be cured in accordance with good concrete practice including water spray and spray applied curing membrane.

Fire

Easiflow CS Grout is non-flammable.

Yield

Each 25kg bag of Easiflow CS Grout will yield approximately 13.25 litres of mixed
grout.

Each 25kg bag of Easiflow CS Grout plus 25kg of 6mm aggregate will yield approximately 22 litres of mixed material.

Temperature in use

Easiflow CS Grout may be placed at temperatures between 5ºC and 45ºC. For placing at temperatures outside this range please contact the Polycote Technical Department.

Safety Factors

Easiflow CS Grout is alkaline when mixed with water and should not come into contact with skin or eyes. Avoid inhalation of dust during mixing and
wear safety glasses, dust mask and gloves. Should eye contact occur rinse immediately with plenty of clean water and seek medical advice. For full health and safety data refer to the Materials Safety Data Sheet.

Before using this product, please ensure you have received and read carefully both the Hazard Label applied to the container and the relevant Material Safety Data Sheets.
