Value Added Options
Air Entrained
Air entraining admixtures reduce the surface tension of the water, allowing air bubbles to form during mixing and remain dispersed throughout the concrete. The benefits of this include freeze-thaw resistance, improved workability, reduced segregation and bleeding, and increased durability.
Accelerators
Accelerators are additives mixed into concrete to accelerate the setting and hardening of the cement, leading to faster strength development. The benefits of this admixture include faster construction, earlier formwork removal, and increased earlier strength.
Hydration Stabilizers
Hydration stabilizers are admixtures used to control and manage the hydration process by slowing down the rate at which the cement hardens. The benefits of this additive include extending the placement and finishing times and reducing waste while improving quality.
Plasticizers
A plasticizer is an additive that reduces the amount of water needed to achieve the desired consistency. The benefits of this admixture include increased strength and durability, improved workability, reduced shrinkage and cracking, and the ability to transport concrete over longer distances.
Corrision Inhibiting Admixtures
This admixture is used to prevent or slow down the corrosion of steel reinforcement within the concrete. By increasing the passivation state of the steel, they create a protective layer on the metal surface that prevents corrosion from starting.
Shrinkage Reducing Admixtures
This chemical additive is used in concrete to minimize the volume reduction (shrinkage) that occurs as the concrete dries and hardens. This reduces the risk of cracking, which increases the durability of the cured cement. This application is especially useful where shrinkage cracking is a major concern, such as concrete floors and slabs.
Colour Admixtures
A colour admixture is added during mixing to give the concrete a specific colour throughout its entire mass, rather than just on the surface. It is used in various applications, including decorative concrete, architectural elements, and even structural components, when colour is needed throughout.
Fibres
This admixture is particularly effective in controlling plastic shrinkage cracking (occurring during the setting and hardening process) and drying shrinkage cracking (occurring due to moisture loss). Fibres act as a secondary reinforcement, enhancing the concrete’s properties and performance.
