Conplast WP410 F is a chloride-free liquid admixture for the manufacture of waterproof concrete and mortar.

Uses

• Sewage treatment plants
• Channels
• Power stations
• Hydraulic works
• Pipelines for water conduction
• Swimming pools
• Underground concrete walls
• In general, all types of concrete and mortar that must be in contact with water.

Advantages

• Gives properties of water-repellent mortars and cement.
• Increases waterproofing due to its water-repellent action.
• Effectively reduces capillary water absorption.
• Maintains the setting time unchanged.
• Significantly increases the durability of concrete and mortar parts.

Standards

Conplast WP410 F complies with UNE-EN 934-2:2010 Table 9 as a bulk water-repellent.

Typical dosage

The optimum dosage of Conplast WP410 F to achieve specific requirements should be determined by tests, using the materials and conditions that will be used in practice.

A starting point for such tests is to use a dosage between 0.5 and 2.0 % by weight of cement.

Properties

The following results were obtained at a temperature of 20°C:

• Appearance: White liquid
• Density: 1,025 ± 0,01 kg/l
• pH: 12 ± 1,0
• Water soluble chloride content (CI-): ≤ 0,10%.
• Alkali content (Na2O equivalent): max. 2 % by mass
• Primary function: Waterproofing
• Secondary function: Increasing durability

Mode of application

Remarks

When producing waterproof concrete, the following points should be observed:

- Correct granulometric curve.

- Minimum w/c ratio.

- Sufficient cement dosage.

- Mixing time.

- Curing and strength of the concrete.

Compatibility

Conplast WP410F is compatible with other Fosroc Euco admixtures used in the same concrete mix. If more than one admixture is used, they must be added to the concrete separately and not mixed together prior to being added. The resulting properties of concrete containing more than one admixture must be checked by prior testing.

Conplast WP410F is suitable for use with all cements complying with RC-08.

Dosing system

The correct quantity of Conplast WP410F should be measured by means of a recommended dosing system. Normally the admixture is added to the concrete together with the mixing water, in order to obtain the best results. Contact the Fosroc Euco Technical Department for advice on suitable equipment and installation.

Effects of overdosage

Overdosing does not have any negative effect on the final qualities of the concrete.

Curing

The final characteristics of any structural concrete will depend on good curing practice. It is therefore very important to use a curing membrane such as Fosroc Euco Concure, water spray or wet burlap.

Clean-up and disposal

Spills of Conplast WP410F should be absorbed with sand or earth and transferred to suitable containers. Product residues should be flushed away with a large amount of water. Disposal of the product and packaging is the responsibility of the end user.

Storage

Conplast WP410 F has a storage period of 6 months if kept in a dry place and in its original, closed containers at a temperature between 5ºC and 30ºC.

Freezing point: -3 ºC approx.

The frozen product should be thawed slowly and shaken afterwards (do not thaw directly).

Precautions

Safety and hygiene

Conplast WP410F is alkaline and irritant and must not be swallowed or come into contact with skin and eyes. Wear protective gloves and goggles. Splashes on the skin should be washed off with water. In case of contact with eyes, flush with plenty of water and seek medical advice. If swallowed, seek immediate medical attention. Do not induce vomiting.
