Product Description
Rheofit 1100 is a ready-to-use liquid admixture formulated to accelerate the setting time and strength gain of non-plastic concrete. Rheofit 1100 is recommended for non-plastic concrete requiring faster setting times and strength (compressive and flexural) gain in any temperature conditions. Note: Rheofit 1100 contains added calcium chloride. Should restrictions on chloride contents apply, contact your local BASF Construction Chemicals Technical Representative to determine the levels of chlorides present for particular dose rates of Rheofit 1100.
SikaRapid® 1 is a high early strength accelerator for concrete and mortar. It increases the early strengths of concrete without negatively influencing final strengths, or reinforcement.
SikaRapid® 1 is recommended for use in concrete where high early strengths are required. This includes:
• Precast concrete, enabling efficient mould utilisation and eliminating or reducing steam curing.
• Prestressed concrete, where early release of stressing cables is necessary.
• Ready-mix concrete, where minimum time delays are critical.
• Colder temperatures, where accelerated strength development is necessary.
• In tidal conditions, where wave action may damage fresh concrete.

SikaRapid® AF is a non chloride set accelerator for concrete and mortar.
SikaRapid® AF is recommended for use in premix and precast concrete where accelerated setting times are required. As a result, SikaRapid® AF allows:
• Faster finishing of concrete surfaces.
• Improved early strength of premixed concrete.
• Rapid slip-form movement.

Sika® Set Accelerator is an accelerator designed for the premixed concrete industry. SikaSet® Accelerator contains calcium chloride and improves the plastic and hardened properties of concrete such as workability, compressive and flexural strengths and freeze-thaw resistance. It is a chloride base material, compatible with air entraining agents, but should be dispensed separately into the concrete mix. It can be used for:
• Cold weather concreting.
• Structural concrete.
• Concrete blocks.
• Concrete pipe and many pre-cast items.

Sika® 4A is a quick-setting waterproofing liquid admixture for Portland cement based mortar.
Sika® 4A is used for surface waterproofing against water infiltrations in porous rock or concrete as well as for cracks and joints through which water infiltrates.
For use in building construction and civil engineering, in particular where dry conditions are required for the following permanent waterproofing operations. Sika® 4A can also be used in quick setting mortar for assembly work, eg. fixing climbing irons, rag bolts, pipe supports, bolts, anchorages and repair work.
