  Conplast SP337*   High performance water reducing admixture Uses   ! To significantly reduce the water demand of a concrete mix without reducing workability, allowing greatly increased early and ultimate strengths without additional cement. ! To significantly improve the workability of concrete without increasing water demand. ! Particularly suitable for increasing workability of ready mixed concrete at elevated temperatures. ! To reduce concrete permeability and thereby reduce water penetration and enhance durability. Advantages ! Use in production of flowing concrete permits easier construction with quicker placing and compaction and reduced labour costs. ! Workability loss in high workability concrete is slower than normally found with superplasticisers. ! Major increases in strength at all ages without increased cement contents are of particular benefit in pre-cast construction. ! Reduction in water:cement ratio enhances durability, producing low permeability concrete with reduced shrinkage cracking potential. ! Chloride free, safe for use in pre-stressed and reinforced concrete. Standards compliance Conplast SP337 complies with BS5075 Part 3 and with  ASTM C-494 as Type A, Type F and Type G, depending on dosage used. Conplast SP337 complies with the requirements of the United Kingdom Water Fittings Byelaws Scheme and is listed in the Directory of Materials as suitable for use in contact with potable water under its previous name of Conplast SP337 Description Conplast SP337 is a chloride free high performance water reducing admixture based on specially selected and blended organic polymers. It is supplied as a brown solution, which instantly disperses in water.   Conplast SP337 disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively. The improved dispersion of cement particles enhances the efficiency of hydration. Technical support Fosroc provides a technical advisory service for on-site assistance and advice on mix design, admixture selection, evaluation trials and dispensing equipment. Dosage The optimum dosage of Conplast SP337 to meet specific requirements should always be determined by trial mixes using the materials and conditions that will be experienced in use. For high strength, water reduced concrete the normal dosage range is from 0.50 to 2.00 liters per 100 kg of cementitious material, including PFA, GGBFS and micro-silica. For high workability concrete the normal dosage range is from 0.50 to 1.00 litre per 100 kg of cementitious material. Use at other dosages Dosages outside the normal ranges quoted above can be used to meet particular mix requirements. Contact Fosroc for advice in the cases. Properties   Appearance:  Brown liquid Specific gravity:   Typically 1.190 at 20 o C   Chloride content:   Nil to BS 5075   Air entrainment:   Typically less than 2% additional air is entrained at normal dosages. Alkali content:   Typically less than 72.0 g. Na 2 O equivalent/liter of admixture. A fact sheet on this subject available.   Instructions for use Mix design Where the main requirement is to improve strengths, initial trials should be made with normal concrete mix designs. The addition of the admixture will allow the removal of water from the mix whilst maintaining the workability at the levels obtained before the use of the admixture. After initial trials, minor modifications to the overall mix design may be made to optimize performance.    Where the main requirement is to provide high workability concrete, the starting mix design should be suitable for a pump mix. Advice on mix design for flowing concrete is available from Fosroc. Compatibility Conplast SP337 is compatible with other Fosroc admixtures in the same concrete mix. All admixtures should be added to the concrete separately and must not be mixed together prior to addition. The resultant properties of concrete containing more than one admixture should be assessed by trial mixes. Conplast SP337 is suitable for use with all types of ordinary Portland cements and cement replacement materials such as PFA, GGBFS and micro-silica. Dispensing The correct quantity of Conplast SP337 should be measured by means of a recommended dispenser. Normally, the admixture should then be added to the concrete with the mixing water to obtain the best results. Contact Fosroc for advice regarding suitable equipment and is installation. Effects of overdosing  An overdose of double the amount of Conplast SP337 will result in an increase in retardation as compared to that normally obtained at the intended dosage. Provided that adequate curing is maintained, the ultimate strength of the concrete will to be impaired by increased retardation and will generally be increased. The effects of overdosing will be further increased if sulphate resisting cement or cement replacement materials are used. Over dosage may also cause increased air entrainment, which will tend to reduce strength. The degree of this effect will depend on the particular mix design and overdose level. Estimating - Packaging Conplast SP337 is available in drum or bulk supply. For larger users, storage tanks can be supplied. Storage Conplast SP337 has a minimum shelf life of 12 months provided the temperature is kept within the range of 2 o C to 50 o C. Should the temperature of the product fall outside this range then contact Fosroc Department for advice. Freezing point -  Approximately - 3 o C Precautions Health and safety Conplast SP337 does not fall into the hazard classifications of current regulations (see notes 1 and 2 below). However, it should not be swallowed or allowed to come into contact with skin and eyes. Suitable protective gloves and goggles should be worn. Splashes on the skin should be removed with water. In case of contact with eyes rinse immediately with plenty of water and seek medical advice. If swallowed seek medical attention immediately - Do not induce vomiting. For further information consult the Materials Safety Data Sheet available for this product. Fire Conplast SP337 is water based and non-flammable. Cleaning and disposal Spillages of Conplast SP337 should be absorbed onto sand, earth or vermiculite and transferred to suitable containers. Remnants should be hosed down with large quantities of water. The disposal of excess or waste material should be carried out in accordance with local legislation under the guidance of the local waste regulatory authority.
