QUALITY MANAGEMENT - Testing
Materials Inspection and Testing
The QA & Technical Manager, in conjunction with the Area Managers, is responsible for the performance and/or witnessing of inspections and testing at the supplier’s premises to establish compliance with specified requirements. Stage inspection/witnessing activities may comprise the following:
Product Inspections, Samples & Random Checks
All raw materials are visually inspected and random loads systematically sampled and tested in accordance with the specification for those particular materials.
All loads are checked for workability before leaving site. Random concrete loads (typically, every 80M³ or 10-15 truckloads) have samples taken for the testing of workability and compressive strength. Three sample cubes are produced for compressive strength testing; one cube for 7 day
and two cubes for 28 days or, as requested by the customer.
Hourly temperature control checks are undertaken as a minimum and where temperature controlled concrete is produced; every load is physically tested to ensure compliance to the customer’s specification.
Aggregate Test Reports and Frequency
Every six months, third party local Municipality approved Testing Laboratories undertake aggregate testing and produce independent test reports for:
Particle Size Distribution.
Material finer than 75 m in mineral aggregates by washing.
Clay lumps and friable particles.
Density, relative density & absorption of Coarse Aggregate.
Shell Content in Coarse Aggregates.
Determination of Partially Crushed Faces of Aggregates.
Soundness of Aggregates by using Sodium / Magnesium Sulphate.
Ten Percent Fines Value.
Lost Angeles Abrasion.
Acid Soluble Chloride, Acid Soluble Sulphate and Light Weight Particles.
Potential Alkali-Silica Reactivity of Aggregates.
Aggregate Drying Shrinkage.
Copies of the latest independent aggregates test reports are available upon request. MBmix will also produce in-house test reports in accordance with specific customer requirements, as required.
