7.3.9. Deleterious Material Test

Try these first

1. 1.

   What are deleterious materials?

   Hint

   Think about what can weaken concrete.

2. 2.

   Name one testing method for deleterious materials.

   Hint

   Focus on the types of tests we discussed.

3. 3.

   What is the purpose of the Deleterious Material Test?

   • To enhance concrete strength
   • To detect harmful materials
   • To measure aggregate weight

   Hint

   Consider why we test aggregates.

4. 4.

   True or False: Organic impurities can improve adhesion in aggregates.

   • True
   • False

   Hint

   Recall the impact of organic materials.

5. 5.

   You are tasked with conducting a detailed evaluation of aggregates for a large construction project. Describe the steps you would take to test for deleterious materials, including any considerations for lab setups and safety measures.

   Hint

   Think about lab safety and the systematic process of testing.

6. 6.

   Discuss the potential long-term impacts of not performing the Deleterious Material Test on a concrete project. Give examples of how structure integrity might be compromised.

   Hint

   Consider both immediate and eventual structural consequences.
