Sika® Control 40An admixture for minimising drying shrinkage

Technical Data Sheet

DESCRIPTION

Sika Control 40 is a shrinkage-reducing admixture forminimising drying shrinkage. It is normally used inconjunction with a superplasticising admixture. SikaControl 40 increases the cohesion in the pore structureand reduces the contraction (length change) as theconcrete continues to dry out.

USES

Sika Control 40 has been especially formulated for usein high performance concrete with strongly reduceddrying shrinkage and enhanced durability. Sika Control40 is used when the limitation of crack width is important.

ADVANTAGES

* Sika Control 40 does not change any of the otherproperties of the fresh and hardened concrete otherthan a very slight extension of workability retention.

* Reductions in drying shrinkage up to 40% arepossible.

* Compatible with other Sika admixtures.

* Free of Chlorides or other substances that promotecorrosion.

Technical Data (typical)

Form: Liquid

Colour: Red

Density: 1.01

pH: 10.5

Dosage range: 0.5 - 1.5%

All above values are approximate.

Page 16

METHOD OF USE

The admixture should be added to the concrete duringthe water addition phase of the mixing process. On noaccount should it be added to the dry cement. Generally,the admixture will have no effect on the amount of wateraddition, nor will it affect the workability of the concreteproduced.

PACKAGING

Sika Control 40 is available in 200 litre drums and bulkdeliveries in increments of 1,000 litres.

STORAGE AND SHELF LIFE

The storage life of Sika Control 40 is a minimum of 12months in sealed containers. Precautions should betaken to avoid storage in temperatures below freezingpoint.

Handling PrecautionsSika products are generally harmless provided that certain precautions normally taken when handling chemicals are observed. The materials must not, for instance, be allowed to come in contact with foodstuffs or food utensils andmeasures should also be taken to prevent the uncured materials from coming in contact with the skin, since people with particularly sensitive skin may be affected. The use of protective clothing, goggles, barrier creams and rubber glovesis required. The skin should be thoroughly cleaned at the end of each working period either by washing with soap and warm water or by using a resin-removing cream - the use of powerful solvents is to be avoided. Disposable papertowels - not cloth towels - should be used to dry the skin. Adequate ventilation of the working area is recommended. In case of accidental eye or mouth contact, flush with water - consult a doctor immediately. Health and Safety informationon Sika Products is available and we strongly advise that this is read prior to their use. Sika products are for professional use and should be stored in sealed containers away from the reach of children.

Important NoteThe information, and, in particular, the recommendations relating to the application and end-use of Sika products, are given in good faith based on Sika’s current knowledge and experience of the products when properly stored, handledand applied under normal conditions. In practice, the differences in materials, substrates and actual site conditions are such that no warranty in respect of merchantability or of fitness for a particular purpose, nor any liability arising out ofany legal relationship whatsoever, can be inferred either from this information, or from any written recommendations, or from any other advice offered. The proprietary rights of third parties must be observed. All orders are accepted subjectto our current terms of sale and delivery. Users should always refer to the most recent issue of the Technical Data Sheet for the product concerned, copies of which will be supplied on request.

The table below details testing on a high flow self-smoothing screed in order to give a comparableshrinkage to a normal workability screed.

The normal dosage to achieve the benefits shown above is 0.5% on cement content. However, there isno detriment to using up to 1.5% on cement if desirable and required.
