Raw Materials
Review and testing of cementitious materials, aggregates, water and admixtures according to the applicable requirements.
Quality assurance
Quality control starts with materials and batching accuracy, continues through fresh-concrete testing, and is verified through hardened-concrete performance.
Control framework
Testing is supported by documented batching information, calibration checks and traceability appropriate to the approved project requirements.
Review and testing of cementitious materials, aggregates, water and admixtures according to the applicable requirements.
Computerised batching, weigh-system checks, mix identification and production records.
Slump or flow, temperature, air content where applicable, density and visual conformity checks.
Controlled sampling, specimen preparation, identification and curing before strength testing.
Compressive-strength review at specified ages, commonly including 7-day and 28-day results.
Connection of orders, delivery tickets, batch records, samples and test results for controlled review.
Laboratory capability
Laboratory results are reviewed alongside site conditions, batching information and the approved mix requirements. Where performance differs from expectation, technical review is initiated to understand the cause and define appropriate action.
Standards
Testing and control activities are carried out with reference to applicable project specifications and relevant BS EN or other approved standards. Project requirements govern the final inspection and testing plan.
Technical enquiry
Provide the strength class, durability requirements, workability, exposure, pour volume and intended placement method.
