Overview
TCR Engineering, a NABL ISO/IEC 17025:2017 accredited laboratory (NABLT0726MH18640) in Navi Mumbai, tests concrete, cement and aggregates for construction and infrastructure projects. The laboratory runs cube and cylinder compression, flexural and split tensile tests, core testing, rebound hammer and UPV surveys, aggregate characterisation and full physical testing of cement per IS 4031.
Compression testing on cube and cylinder specimens (2,000 kN and 3,000 kN capacity machines). Flexural testing. Split tensile. Core extraction and compression. Rebound hammer surveys. Ultrasonic Pulse Velocity per IS 13311 Part 1. Aggregate crushing value, aggregate impact value, Los Angeles abrasion, specific gravity, water absorption. Cement testing per IS 4031 across consistency, setting time, soundness, fineness, and compressive strength.
How TCR Tests Concrete, Cement, and Aggregates
TCR runs the full concrete-quality workflow: compression testing on cube and cylinder specimens on 2,000 kN and 3,000 kN capacity machines, flexural and split-tensile testing, core extraction and compression, rebound hammer surveys, and Ultrasonic Pulse Velocity per IS 13311 Part 1.
- Compression: cube and cylinder specimens on 2,000 kN and 3,000 kN machines.
- Other strength tests: flexural and split-tensile, plus core extraction and compression.
- In-place assessment: rebound hammer surveys and Ultrasonic Pulse Velocity per IS 13311 Part 1.
- Aggregate: crushing value, impact value, Los Angeles abrasion, specific gravity and water absorption.
- Cement, per IS 4031: consistency, setting time, soundness, fineness and compressive strength.
Aggregate characterisation covers aggregate crushing value, aggregate impact value, Los Angeles abrasion, specific gravity, and water absorption. Cement testing per IS 4031 runs across consistency, setting time, soundness, fineness, and compressive strength. The material range extends to cement (43-grade and 53-grade OPC), GGBS, fly ash, micro silica, admixtures, mixing water, and fine and coarse aggregate.
Governing Standards
Concrete, cement, and aggregate acceptance is governed by the Indian standards below, with ASTM and EN methods available where a project specifies them.

| Flexural strength | Flexural strength of concrete | EN 12390 series |
| Split tensile | Split-tensile strength | ASTM C496 |
| Capping of cylinders | Specimen preparation | ASTM C617 |
| Sampling and analysis | Fresh-concrete sampling and workability | IS 1199 |
| Aggregate tests | Crushing, impact, abrasion, specific gravity, water absorption | IS 2386, IS 383 |
| Cement physical tests | Consistency, setting time, soundness, fineness, strength | IS 4031 |
| Ordinary Portland Cement grade | 43-grade and 53-grade OPC | IS 8112, IS 12269 |
| Concrete code of practice | Plain and reinforced concrete | IS 456 |
| Ultrasonic Pulse Velocity | Concrete homogeneity | IS 13311 Part 1 |
| Concrete mix design | Mix proportioning and trial mix | IS 10262, IS 456 |
