Accelerators

Admixtures which accelerate the setting and/or hardening of a concrete by controlling the hydration process of the cement. Main reasons for using accelerators: Improve early strengths, Concreting in low temperatures, Shotcrete.

SikaRapid®-2

SikaRapid®-2 is a low alkali liquid set accelerator for concrete and mortar. SikaRapid®-2 promotes early strength development without negatively influencing final strengths.

SikaRapid®-3

SikaRapid®-3 is a low alkali liquid set accelerator for concrete and mortar. SikaRapid®-3 promotes early strength development without negatively influencing final strengths.

Sikaset® N

Sikaset® N is a calcium chloride based liquid hardening accelerator for concrete and mortar.

Formwork & Equipment Treatment

Release agent (Separol W) - Product used to enable the release of formwork from the surface of concrete without damaging it. Provides the correct barrier to enable the contractor to achieve an excellent surface finish. Used in all concrete processes that require formwork.
Surface retarder (Rugasol Plus) - Works by retarding the surface of the concrete, useful for creating a day joint which is used to key in the next section of concrete. Also used for architectural finishes.
Equipment protection (Spray Gard, Sika Release) - Spray Gard is used to keep equipment surface free of concrete / cement build up - exterior of mixers, tools etc. Sika Release is similar but used on concrete cube moulds, prism moulds etc.

Sika Rugasol® Plus (20Lt Drum)

Sika Rugasol® Plus surface retarder have been specially designed for producing a mechanical key to construction joints, stop ends, or subsequent rendering applications.

Sika® SprayGard®

Sika® SprayGard® is a ready to use, blend of selected oils developed to protect concrete mixing equipment. Sika® SprayGard® can be applied on all mixing equipment that is in contact with fresh concrete and mortar.

Sika® Release

SIKA RELEASE is a ready to use formwork release agent for concrete and mortar.

Sika® Release Oil

Sika® Separol® W

Sika® Separol® W is a ready to use, solvent and mineral oil free concrete release agent. It is an emulsion, based on biological degradable synthetic oil.

Semi Dry Admixtures

Allow optimal water contents to be used to achieve the best compaction possible. Increasing compaction leads to better green strength, increased early and final strength & economical production of quality concrete.

Superplasticisers / HRWR Admixtures

Will remove large amounts of mixing water to achieve very low water cement ratios whilst providing high workability (generally used for SCC applications). Not only are the 28 day strengths & overall durability of the concrete increased, but due to the addition of set accelerators in all Sika Precast Superplasticisers, the early stripping of formwork is achievable in a matter of hours. Sika Precast Superplasticisers can start setting in as little as 15 minutes.
