Liquid Solutions Precast Admixtures
UKCP CompaktAid is a precast block compaction and processing aid for dry and semi-dry concrete. It improves compaction, density and pigment dispersion, giving better colour intensity, a better surface finish and reduced efflorescence in blocks, paving flags and block paviours.
UKCP CompaktAid is a precast block compaction and processing aid. It is a highly effective block and brick processing aid which improves compaction and density in semi-dry concrete applications.
Its blend of compaction and processing aids provides improved dispersion of pigments, which significantly improves the colour of the cast unit and gives better colour intensity. The compaction aids also increase density, which reduces porosity and in turn helps reduce the occurrence of efflorescence.
Efflorescence is the white, powdery deposit that can appear on the surface of concrete and masonry. It forms when water carries soluble salts to the surface and then evaporates, leaving the salts behind. It is a common concern for coloured blocks and paving, because it dulls the appearance of the finished product.
CompaktAid is used to improve compaction and handling of all dry and semi-dry concrete processes, including:
Improved compaction properties also result in reduced machine stress and parts wear. For a high performance option that also targets binder reduction and roof tile production, look at CompaktAid Plus.
Dosage rates vary depending on mix design, process, aggregate type and the required consistency. Typical dosage rates range from 200ml to 600ml per 100kg of cement, which is 0.20% to 0.60% by weight of cement.
These figures are a guide only. The correct dosage for your process should be determined by laboratory trials, so confirm it with trials and with our technical support team.
For health and safety information, please refer to the Safety Data Sheet, available on request.
CompaktAid is supplied in 200 litre drums and 1000 litre IBCs. Protect the product from extreme temperature, frost and direct sunlight. It has a minimum shelf life of 12 months.
