Curing & Release Agents
duracure acrylic

USES:
duracure acrylic is an economical method to assist in efficient concrete curing. The product acts chemically with the hydroxides produced by the hydration of cement to form a dense porefilling crystalline structure that in turn reduces the water evaporation rate from the concrete surface. The presence and retention of water in concrete is essential to ensure adequate strength development and minimise initial plastic shrinkage crack development.
ADVANTAGES:
• Compatible for water retaining structures (potable water)
• Economical, single application reduces incidence of shrinkage cracks
• Promotes better strength gain characteristics
• No film breakdown period involved
• Does not interfere with subsequent concrete surface treatments (paints, emulsions, sealants adhesive, renders, tile adhesives, etc.)duracure PR-C and PR-W

coverage rates.
Mortars
abefix TBM (thin bed mortar)
abefix TBM is a polymer modified cement based mortar
adhesive which is used to bond concrete blocks/bricks together instead of the more time consuming traditional thick mortar bedding system. The action of abefix TBM is to provide a thin but very strong bond between block/brick faces due to the optimum curing conditions gained by the modified cement within the product.
USES:
Blocks having low tolerances and smooth bonding faces can be laid very rapidly when using abefix TBM.
• Interlocking blocks bonded together using abefix TBM
provides a very strong wall as opposed to conventional
mortar.
