Superseal D5 Water Proofing Concrete Admixture

• Increases waterproofness of concretes up to W12 – W20 and more. No additional damp proofing of concretes is required. This high level of water proofing is retained for complete life of the concrete structure.
• Super Plasticizes concrete mix. Increases flowability of concrete mix from slump 30-40 mm up to slump 180-220 mm or reduces water consumption by 15-30 % when maintaining flow ability (slump) of concrete mix
• Controls retentivity of flow ability (retention of consistency) of concrete mixes during 3 hours and more (even under conditions of a hot climate at temperature of air up to +50°?)
• Accelerates the process of concrete hardening. Normalized 100% concrete strength is reached for 5th.-7th.day of hardening under normal conditions
• Increases concrete strength by 30-70% comparing with concrete without admixture
• Increases frost resistance not less, than 50 cycles
• Increases sulphate-resistance of standard Portland - cement concretes in 3 – 4 times
• Allows to reduce time of cast-in-place construction not less than by 25-30% due to rapid strength setting, reduction of time of its concrete cure in forms and full exception of all additional works on external water proofing of concrete
• Gives to concrete a property of self healing of through cracks up to 0,8 mm wide having been appeared in constructions during working (owing to dynamic loads, including seismic), under condition of water filtration through these cracks. In usual conditions this property provides the fact that even during long intervals in concreting, joints between old and new concrete do not leak and possible leakages subsequently are liquidated by themselves during 7-28 days.
• Allows to exclude warm-moisture treatment when making precast reinforced items, having replaced it by warm- up under conditions of "thermos" at temperature 30-40°C
• Gives to concrete antifreeze properties (up to -15°C)
• Admixture improves protective properties of concrete with respect to steel bars by 46 % compared to control sample
• Increases bond between steel and concrete not less than 30 %
• Increases adhesion of concrete by 50-70 %

SUPERSEAL D5 Admixture does not contain either chlorine or other components dangerous to a cement stone and reinforcement and does not have harmful effect on environment. It is added in production of concrete and reinforced concrete structures and items contacting drinking water.

Recommended Dose
1 % to 3 % by weight of cement in the concrete or plaster for most of its applications

Period of storage:
Not less than 12 months in dry conditions.

Usage Instructions:

• SUPERSEAL D5 Admixture dry powder should be sprinkled by hand to the initial water in the concrete mixer, the quantity of which should normally be less than 60 % of the expected quantity of water for given water cement ratio. The mixture should be rotated for 1 minute for a thorough mixing of the admixture before adding aggregate, cement and sand to the mix. The required slump is achieved by adding additional water. The total mixing time should exceed 3 minutes. Please note that to maintain the same slump, water quantity will reduce by 15 % to 30 %. Higher the quantity of admixture, lower will be the water requirement for achieving the same slump.
• When it is required to provide retentivity of flow ability (retention of consistency) of concrete mixes during 2 hours and more, it is necessary to use cement CEM I 42,5 with dosage of cement not less than 320 kg/m 3 and to make concrete mix with SUPERSEAL D5, 3 % by weight of cement with initial slump 210 – 230 mm.
• Thus, higher will be a dosage of SUPERSEAL D5, longer concrete mix will keep its flow ability and the higher will be concrete strength. At a dosage of the admixture 1,5 % of cement mass, it is provided high flowability and pumpability of concrete during 1,5 - 2 hours, and at a dosage 3 % - during 3 - 5 hours. At that, during the first 24 hours there can be observed some delay of concrete hardening process. However, from the second day onward concrete will gain accelerated strength setting and on the 7 th day concrete will achieve 100 % strength, which will reach by the 28 th day, at least, up to 130 % of normative
• In preparing mortar for wall plaster or minor repairs in small batches, required proportion of SUPERSEAL D5 be mixed in dry cement thoroughly and dry mixture of cement and D5 used for preparing mortar. Care should be taken to add water in smaller quantities and consistency and flowability be checked before adding the final required quantity of water. D5 will require lesser amount of water for same flowability. Homogeneous and thorough mixing will give better results
• Transportation of concrete mix up to an object of construction should be necessarily carried out in mixer trucks by constant stirring of concrete mix. Time from the moment of production of concrete mix before the beginning of its placement against forms should not exceed 60-90 minutes value
