Admixtures

Admix Products​

Admixtures are additional ingredients added to ready mix concrete during the mixing process to alter its properties and enhance performance. They can improve various aspects of the concrete, such as workability, strength, durability, setting time, and resistance to adverse conditions. American Ready-Mix uses a full range of Admixes, as appropriate for the particular mix design, in accordance with appropriate ASTM standards. Our Ad-Mixes offer you maximum flexibility in your mix specifications and allow you the type of mix, delivered to your site that will be easy to finish and develop the strengths you require. We offer Fiber Concrete as a specialty.

Enhanced Performance​

Admixtures play a crucial role in enhancing the performance of ready mix concrete. Whether it’s improving workability, accelerating or retarding setting time, enhancing durability, or providing resistance to adverse conditions such as freeze-thaw cycles, admixtures can significantly improve the overall quality and longevity of concrete structures.

Tailored Solutions​

Admixtures offer consumers the flexibility to tailor ready mix concrete to meet specific project requirements. Whether it’s adjusting the slump for easier placement, increasing early strength development for rapid construction, or enhancing the durability of concrete in harsh environments, there’s a wide range of admixtures available to address various needs and challenges.

Types of Admixtures and what they are used for​

By understanding the importance of admixtures in enhancing concrete performance, recognizing the benefits of tailored solutions, and seeking expert guidance, consumers can make informed decisions when buying admixtures for their ready mix concrete projects, ultimately leading to successful and durable construction outcomes.

  1. Water Reducers (Plasticizers): These admixtures reduce the amount of water needed in the concrete mixture while maintaining workability. By allowing for a lower water-to-cement ratio, water reducers improve concrete strength and durability.

  2. Retarders: Retarders slow down the setting time of concrete, allowing more time for transportation, placement, and finishing. This is particularly useful in hot weather conditions or large-scale projects where extended workability is necessary.

  3. Accelerators: Conversely, accelerators speed up the setting time of concrete, enabling faster strength development. They are beneficial in cold weather conditions or when rapid construction progress is required.

  4. Air Entrainers: Air entraining admixtures introduce tiny air bubbles into the concrete mixture, enhancing freeze-thaw durability and workability. These bubbles act as a relief mechanism, reducing internal pressure and preventing cracking caused by freeze-thaw cycles.

  5. Superplasticizers: Also known as high-range water reducers, superplasticizers greatly improve the workability of concrete without increasing water content. They are often used in self-consolidating concrete and high-performance concrete mixes.

  6. Corrosion Inhibitors: Corrosion inhibitors protect reinforced concrete structures from corrosion by reducing the permeability of concrete and inhibiting the penetration of chloride ions or other aggressive chemicals.

  7. Coloring Agents: Coloring admixtures can be added to concrete to achieve a wide range of colors beyond the standard gray. They are commonly used in decorative concrete applications such as stamped concrete, stained concrete, and architectural finishes.

  8. Fiber Reinforcement: Fibers such as steel, synthetic, or natural fibers can be added to concrete to improve its tensile strength, crack resistance, and toughness. Fiber-reinforced concrete is commonly used in industrial floors, pavements, and precast products.
