Concrete Testing

Field Sampling & Testing

• Fresh concrete sampling, including test for temperature, slump, unit weight, and air content test by pressure and volumetric method
• On-site casting and curing of concrete samples
• Specific gravity test of grout by mund-balance
• Inspection of ready-mix plant operations for QA, including sieve analysis and determination of water-cement ratio

Laboratory Testing

• Compressive and flexural strength testing
• Rapid chloride permeability test (RCPT)
• Length change, drying shrinkage
• Density, water-soluble chloride
• Elastic modulus and creep testing (if required)

Core Sampling & Evaluation

• Extraction by core drilling from hardened concrete
• Testing for compressive strength and length measurement

Newly Added Advanced Tests:

• ASTM C495 – Compressive Strength of Lightweight Insulating Concrete
  Used for determining compressive strength of lightweight cellular or insulating concrete used in roofing systems and specialty applications.
• ASTM D4832 – Preparation and Testing of Controlled Low-Strength Material (CLSM) Test Cylinders
  Evaluates flowable fills and backfill materials (aka “lean concrete”), frequently used in utility trench restoration or underneath pavements. Ensures performance under load and ease of excavation if necessary.
• ASTM C1550 – Flexural Toughness of Fiber-Reinforced Concrete (Round Panel Test)
  Measures the energy absorption and ductility of fiber-reinforced concrete through load-displacement response of a centrally loaded round panel. Especially relevant for pavements, overlays, and tunnel linings.
