Concrete admixtures are either natural or manufactured chemicals that people add to concrete before or during mixing. Ducon Construction Chemicals, for instance, produces a diverse range of concrete admixtures in Bangladesh to address specific needs. Common types of admixtures include air-entraining agents, water reducers, retarders, and accelerators. To use these admixtures successfully, you must follow proper batching and concreting methods. Typically, most admixtures come as ready-to-use liquids, which you can add to the concrete either at the plant or the job site. Additionally, the effectiveness of a waterproofing admixture in Bangladesh relies on several factors, such as the type and quantity of cement, water content, mixing time, slump, and concrete temperature. Furthermore, in some situations, you can achieve similar effects to those of admixtures. This approach includes reducing the water-cement ratio, using different types of cement, or modifying the aggregate and its gradation.
