The engineering of concrete structures is a continuously evolving process. Invention and development of new construction methods place increasing demands on the building materials.

Concrete batching plant using Sika admixtures for ready mix concrete production

Concrete producers face this technological challenge daily alongside  other factors such as economy, ecology, raw material, and energy costs  and logistical complexity. In the duration  of the whole construction  process, time itself is an increasingly important factor.

Sika provides a wide range of concrete admixtures with innovative options for concrete mix design, whether it's for substantially reducing the water content of a mix, using a more economical mix design or achieving sufficient early strength. Sika's concrete admixtures help you meet the challenges of modern concrete technology and the construction business.

Sika Ready-mix Concrete Admixtures

Water Reducers & Plastisizers

Full range of water reduction technologies from water reducer to high range water reducer combined with controlled setting times and all application requirements

Mid Range Water Reducers & Super Plastisizer

Incorporated at the mixing stage of concrete, they represent 0.3 to 0.5% of the cement’s weight. They improve the rheology of fresh concrete and offer superior workability.

Set Controlling Admixtures

Specific set retarders allow to apply the concrete as along as recommended. Different types of accelerators (SikaRapid) controlling the high early strength development as well as the phase of “green concrete”.

Concrete Essentials

A wide range of add ons complete the product range like mould release agents (Separol), curing compounds (Antisol) and surface retarders (Rugasol).

Air Entrainers

Sika Aer Technology used where high resistance to freez/thaw or better fresh concrete properities is required by introducing correctly sized and evenly distributed  Air pores into the concrete.

Fibre Products

Sika Fiber technology improves the tensile characters of the concrete and preventes the microcracking due to plastic and drying shrinkage in cementitious systems.

Special Purpose Concrete Admixtures

Sika provides admixtures systems for underwater concrete, pumpabel concrete, and concrete additives like Sika Silica Fume peoducts.

Ultra High Range Water Reducers

High range water reducers and superplasticizers achieve significant water reduction required for the fluidity of fresh concrete. They increase compressive strength of concrete and maintain an excellent workability and flowability. Ideal for the production of Self Consolidating Concrete (SCC) and other types of concrete.
