This document outlines the requirements for concrete batching plants and laboratories. It discusses general plant requirements including computer controlled batching, plant type, printouts and calibrations. It also covers material storage and handling, factory conditions, and waste management. Laboratory requirements include equipment calibration and validity, curing rooms, test records, and traceability. Approved material sources must meet specifications, be properly implemented, and facilities and staff must be certified. The document provides guidance on concrete mix design, testing methods, and quality control.
