Key Responsibilities:

Concrete Testing:

• Fresh Concrete Slump Test: Perform slump tests to measure the consistency and workability of fresh concrete mixes.
• Concrete Cubes Preparation: Prepare concrete cube samples for compressive strength testing.
• Concrete Cube Compressive Strength Test: Conduct compressive strength tests on concrete cubes and record results.

Aggregate Testing:

• Sieve Analysis for Coarse and Fine Aggregates: Conduct sieve analysis to determine particle size distribution for both coarse and fine aggregates.
• Fine and Coarse Aggregate Fines Content Test: Measure the amount of fines in both coarse and fine aggregates to ensure compliance with specifications.

Soil and Density Testing:

• Proctor Test for Compacted Soil: Perform Proctor compaction tests to determine the optimum moisture content and maximum dry density of soil.
• Sand Cone Test for Field Density: Conduct field density tests using the sand cone method to determine in-place soil compaction.

Documentation and Reporting:

• Maintain accurate records of all tests performed, including the test methods, results, and any observations.
• Prepare and submit test reports as per industry standards and project specifications.
• Ensure compliance with safety standards and laboratory protocols.

Laboratory Maintenance:

• Ensure all laboratory equipment is calibrated, well-maintained, and in proper working condition.
• Assist in organizing and maintaining laboratory supplies and materials.

Collaboration and Communication:

• Work closely with engineers, project managers, and other stakeholders to ensure test results meet project specifications.
• Communicate results and any anomalies to senior laboratory staff or engineers.
