EURIPEL W2 is a permeability reducing admixture for use in all types of mortar and concrete mixes. It is particularly suitable for use in ready-mixed concrete and all types of structural concrete. It is also usefully employed in precast concretes involving the use of wet concrete, semi-dry concrete and cast stone. EURIPEL W2 is formulated from carefully selected raw materials and is manufactured under controlled conditions to give a consistent product. It is based on a blend of long chain carboxylic acids to give maximum reduction in permeability without inhibiting side eects. This results from a positive chemical action which creates a network of insoluble water resistant material within the pores of the cement matrix.
EURIPEL W2 is supplied ready for use, and may be added to the mix water prior to addition to the aggregate. EURIPEL W2 will not entrain air when used in wet concretes, but will plasticize the mix and cause a significant increase in workability. It is necessary to reduce the free water content of concrete mixes containing EURIPEL W2 to maintain constant workability. If the free water content is not reduced, then an increase in workability will result and there may be some loss in compressive strength. No extension of normal mixing time is necessary.
• Permeability reduction can be achieved without significant changes in strength
• EURIPEL W2 can be added by means of an automatic dispenser
• Precast units, blocks bricks and in situ concrete containing this type of admixture have been shown to retain their original clean appearance when exposed to the elements for considerable periods.
• The durability of concrete finishes is increased since the penetration of rain and dew is greatly reduced giving improved resistance to frost damage.
• Aggregate ‘mottling’ can be prevented in most mixes
• The reduction in permeability obtained with EURIPEL W2 is long lasting
• No problems of settlement in storage are encountered
