Florida DOT Concrete Batchman/Operator Practice Exam

How should admixtures be stored?

1. At ambient temperature

2. Under specific humidity conditions

3. According to the manufacturer's recommendation

4. In any available storage area

The correct answer is: According to the manufacturer's recommendation

The correct approach to storing admixtures is to follow the manufacturer's recommendations. Manufacturers design their products with specific formulations that may require certain storage conditions to maintain their effectiveness and performance. These conditions could include temperature ranges, humidity levels, light exposure, and protection from contaminants. By adhering to these guidelines, you ensure that the admixture will perform as intended when mixed with concrete. While other storage options may seem reasonable, they lack the precision required for optimal performance. Storing admixtures at ambient temperature may not be suitable for all products, and not all chemical admixtures can tolerate high humidity without degrading. Utilizing any available storage area might expose the admixtures to environmental factors that could compromise their quality. It is essential for operators to understand and implement the manufacturer's specifications to ensure the reliability and integrity of the concrete mix.
