The properties of the ready-mixed concrete in the fresh and hardened states are prone to variations on account of a number of factors. These properties are dependent upon the properties of different ingredients used in concrete, the process control measures, optimization efforts in mix proportions and the degree of quality control exercised by the producer.
- Strict control on the quality of all input materials used in production through rigorous in-house or third-party testing
- Stringent process control measures involving thorough inspection, good upkeep of equipment, monthly scale calibration of weighing devices, etc.
- Continuous monitoring of the key properties of concrete in the fresh and hardened states, including their statistical analysis
- Adopting the world-renowned Quality Scheme for Ready-Mixed Concrete (QSRMC) from U.K, for ensuring QA & QC. This involves continuous monitoring on all stages of production and supply i.e. order processing, purchase/control on input materials, concrete mix design, process control, sales, delivery and statistical quality control.
The Company’s production facilities in different locations are supplemented with a state-of-the-art central laboratory for testing of concrete and its ingredients. All central laboratories are fully equipped with latest testing equipment conforming to the requirements of relevant codes of the Bureau of Indian Standards. The routine tests done in the laboratories include the following:
- Aggregate gradation (once in a week)
- Moisture content (at least twice in a day)
- Silt content
- Plastic Density
- Compressive strength of concrete: at 28 days ( 7/56/90 – day testing optional, depending on customer requirement)
