Concrete Admixtures & Additives

Available Concrete Admixtures / Additives

Integral Concrete Sealer

Sealers are vital in maintaining a strong, efficient concrete surface. While many sealers can be applied to the surface following a pour, integral concrete sealers are added directly to the mix, ensuring even distribution of the sealer. These sealers (like Ozinga’s OzShield) not only help protect concrete more effectively than surface sealers, but they also save time by being added to concrete before it arrives on site.

Concrete Accelerator (Calcium Chloride, NCA/DCI)

Concrete accelerator is used to speed the setting time of concrete, allowing it to begin to cure earlier than a typical mixture. This can be especially useful for cold weather placements, as the reduced setting and cure times can lower the risk of frost damage.

Concrete Plasticizer

Plasticizers increase the workability of concrete mixtures. This is useful in high-strength mixes that can be difficult to mix and would have their strength reduced by the addition of water.

Concrete Retarder

Concrete retarders are added when a mixture needs to have a longer setting time. This is often used to slow the hardening of the surface so that the top layer can later be washed off to achieve an exposed aggregate look.

Concrete Water Reducer

Water reducers are typically added to concrete mixtures before they are poured on a job site. Reducing water content in concrete can help decrease porosity, which can minimize the space available for water to enter and cause damage during freeze-thaw cycles. They can also increase workability and overall concrete strength.

Corrosion Inhibitor

Corrosion inhibitors are used to extend the surface life of steel-reinforced concrete structures. They are effective in reducing the rate at which moisture and chlorides enter concrete, which can aid in corrosion.

How to Maintain Concrete

Whether you have a large concrete driveway or a small concrete patio, you want to extend the life of the flatwork and keep it looking great for a long time. Knowing how to maintain concrete can be the difference between concrete that grabs attention versus concrete that people are scared to walk on. Thankfully, maintaining

Ozinga Earns Three Design Awards for Outstanding Concrete from IRMCA

Ozinga earned three awards and recognition from the Indiana Ready Mixed Concrete Association (IRMCA) for our concrete application. Our first award was for Bulldog Park in Crown Point, IN. Of the 2160 cubic yards in this project, nearly half was used on the exterior flatwork and a pavilion/ice rink floor.
