Senior Lab Chemist Interview Questions and Answers

The question seems to be asking about the consequences of not using admixture dosage in a lab setting.

• Without admixture dosage, the properties of the material being loaded may be compromised.

• Admixture dosage is important for achieving desired characteristics such as strength, workability, and durability.

• For example, in concrete mixing, not using admixture dosage can result in lower strength and increased permeability.

Admixture dosage for design is applied based on the specific requirements of the project and the properties of the materials being used.

• Determine the desired properties of the concrete mix, such as strength, workability, durability, etc.

• Consult the manufacturer's recommendations for the admixture being used.

• Calculate the appropriate dosage based on the desired properties and the specific admixture being used.

• Perform trial mixes to determine the optimal dosage for the desired ...read more

High admixture dosage can lead to negative effects on concrete properties and performance.

• High admixture dosage can weaken the concrete structure

• Excessive admixture dosage can lead to delayed setting time

• Overdosing admixtures can cause segregation and bleeding in concrete mixtures
