ABSTRACT
The supervisor responsible for the concrete structure will generally have the benefit of substantial back-up as regards concrete quality control. Most contractors have a department, or at least a person, usually an engineer, to deal with the underlying concrete technology of construction. The duties of this department or person will include:
formal details of quality control; ensuring that aggregates, cement, water and admixtures conform with the local specification; carrying out prescribed trial mixes; sampling and testing materials and fresh concrete; testing hardened concrete and ensuring compliance with specification requirements; ensuring that weigh batching plant and measuring equipment is maintained and regularly
calibrated; conducting special tests such as using covermeter, Schmidt hammer and pulse velocity equipment
in non-destructive testing, as required; dealing with problems which arise in the event of non-compliance with specification.
