Admixture

Concrete admixtures use is increasing very rapidly and its importance is becoming more valuable. Ordinary concrete may not give us the required quality performance such as durability, strength, workability and finishing quality of concrete. In such situations, concrete admixtures are used to modify or improve ordinary concrete properties. i.e. mass concreting, concreting at narrow spaces, at remote places where water is not available easily, where formwork needs to be removed early, concreting work near coastal areas, etc. They are also used to overcome placement emergencies such as equipment failure and other unexpected delays. Admixtures also reduce the cost of the concrete mix and compensate for poor aggregate properties. Rapid advancements in building technologies, increasing demand for sustainable construction, rising research and development, increasing availability of Concrete admixture, changing construction industry landscape and rapid infrastructural developments are some of the major factors that propel the Concrete admixture market.
