All participants in the construction process want to achieve sufficient early strength to allow formwork removal as quickly as possible, whether in shotcrete for construction sites or in concrete production.   

Depending on the concrete mix design and process requirements it is possible to accelerate concrete hardening in several challenging conditions.

Set Control & Hardening Accelerator Product Categories

Depending on their location and use, concrete structures are subjected to a wide range of exposure conditions – from normal atmospheric carbonation to the aggressive influences in polluted urban and industrial environments, plus marine atmosphere and liquid or gaseous chemicals, along with influencers that can damage or attack the concrete and embedded steel reinforcement.

Set Control and Hardening Accelerator-Retarders

Retarders

What are retarders? Retarders are typically used to delay the onset of setting or to increase the setting time and thereby also to increase the available processing or production times of gypsum, cement and other mineral binder systems. Retarders are typically used to delay the onset of setting or to increase the setting time and thereby also to increase the available processing or production times of gypsum, cement and other mineral binder systems. Specific site requirements regarding extended workability time of fresh concrete before hardening can be perfectly tailored with the help of set retarders.

Hardening Accelerators

What are hardening accelerators? In an industrialized rapid precast production the concrete hardening process represents the decisive step for production output. Depending on the production speed and produced concrete elements formwork removal can be necessary only after some hours.
Set Control and Hardening Accelerators-Hydration Control

Hydration Controlling

Why use hydration controlling? In summer, when temperatures are high, we need more hydration control to keep the concrete workable and pumpable. In winter though, we need more accelerators to speed up the curing process.

Set Accelerators

SikaSet® are accelerators for controlling the set of backfilling grouts. The use of SikaSet® NC, a non-chloride accelerating admixture, during the colder weather assured early strength development without any additional concrete heating.
