Admixtures are specialized additives used in concrete and mortar to enhance their properties and performance. These additives can modify aspects such as workability, setting time, and strength. Types of admixtures include accelerators, which speed up curing; retarders, which delay setting time; and plasticizers, which improve workability without adding extra water. Additionally, admixtures can provide benefits like increased resistance to environmental factors, improved durability, and enhanced bonding. Suitable for a variety of construction applications, admixtures are essential for optimizing the performance and longevity of concrete structures, ensuring they meet specific project requirements and standards.
