• Familiarization with apparatus & equipment used in testing of materials

  Why Is it Important to Be Familiar With Laboratory Apparatus & Their Uses?
• Familiarization with apparatus & equipment used in testing of materials

  1. When Field Testing indicates further study is needed

  2. Laboratory Testing is the next step!
• Construction materials testing laboratories

  • Equipped with laboratory equipment and apparatus
  • Costly
  • Sensitive
• Delay in testing of construction materials

  • Unable to hit the turn-over date
  • Increase the project cost
• Construction material testing


  • Critical for the viability and safety of a construction project
  • It can reveal any number of issues related to construction quality
  • It can highlight future risks, help classify a building site, and assist with engineering decisions
  • Without construction material testing, engineers and builders may not know if the quality of the construction meets the requirements
• Safe Handling


  Laboratory equipment can lead to dangerous side effects and that is why it is quite important to know how to handle properly
• Efficient Use


  Laboratory instruments required the proper knowledge to run or operate them. If they are not operated in the required way, it will not be helpful to churn out the desired results
• Proper Materials


  Many laboratory machines are designed to study and analyze samples from a variety of sources. This sample could be organic or inorganic, vegetable or mineral. Knowing which machine is for which kind of sample and what the machine is supposed to do is good for avoiding trouble
• Understanding Results


  After inserting the correct materials or calibrating a machine correctly, you still won't be able to finish your task unless you understand what it is that the machine has just done. Knowing which sections of any printouts or displays contain the most vital information and what that information means is important to completing the experiment
• Civil engineering projects largely depend on the quality of their materials; therefore testing equipment capable of providing consumers with accurate and repeatable results is imperative
• Properties of the materials tested

  • Aggregates
  • Soil
  • Concrete
  • Asphalt

• Plastic limit tools


  Designed to measure of the critical water content of fine-grained soils
• Shrinkage limit tools


  Designed to evaluates the water content of a soil where further loss of moisture will not result in an additional volume reduction
• Proctor soil compaction test tools

  Designed to understand compaction characteristics of different soils with change in moisture content
• Spatula
