Cement acts as the binding agent or glue in concrete. When combined with water, cement forms a paste that coats the sand and gravel. Through a chemical reaction called hydration, the mixture sets and hardens into concrete.

When freshly mixed, concrete can take any shape or form; when hardened, it’s strong and durable. These qualities explain why one material, concrete, can build everything from skyscrapers and sidewalks to highways and dams.

Slag cement, a byproduct of steel-making, enhances the traditional concrete benefits of strength and durability while offering reductions in waste, energy use and greenhouse gas emissions.

Slag cement is used in concrete for virtually any construction application, either in conjunction with traditional portland cement, part of blended cement or as a separate component. It typically replaces part of the portland cement in concrete mixes.

Fly ash is a byproduct of coal combustion in electric power plants. It’s the very fine ash recovered from exhaust gases by emission-control systems. Fly ash is a pozzolan, virtually identical to volcanic ash.

When used in concrete mixes, fly ash is known as a supplementary cementing material, or SCM. Fly ash is the most widely used SCM, and has been added to concrete since the 1930s. It can supplement cement on its own or used in conjunction with other SCM in blended cements.

Improved Concrete Properties

Sika's admixtures enables concrete to flow easily through and into confined spaces.

Sika® Stabilizer-4R

Durability-Enhancing Admixtures

An essential characteristic of concrete is its durability. admixtures will help concrete performance to their requirements.

SikaControl®75 SikaFume®CRETE DP

Set-Retarding Admixtures

Specific jobs requirements regarding extended workability time of concrete before hardening can be perfectly tailored with the help of retarders.

SikaTard®440 Sika® Retarder

Accelerating Admixtures

All participants in the construction process want to achieve sufficient early strength to allow formwork removal as quickly as possible.




Fiber-reinforced concrete is ideal for improving the durability and toughness performance of concrete and mortar. Fibers in concrete help reduce shrinkage cracks, increase strength, increase energy absorption and reduces dangerous spalling at high temperatures.


Sikacrete® M-100 is highly reactive metakaolin pozzolan for portland cement concrete, grouts and mortars applications. Sikacrete® M-100 meets the chemical requirements of ASTM C-618, Class N pozzolan.​


Sika® Watertight Concrete Powder is a combined water resisting and HRWR/Superplasticizing admixture used to enhance the workability and reduce the water permeability of concrete.


Sika® FerroGard®-903 is a corrosion inhibiting impregnation coating for hardened concrete surfaces. It is designed to penetrate the surface and then to diffuse in vapor or liquid form to the steel reinforcing bars embedded in the concrete.
