Quality Control and Quality Assurance| Concrete

All of the material producers who contribute to concrete construction have quality control programs of various degrees. A program may be only a benign visual determination or it may involve comprehensive testing. The selection and operation of a specific program are usually dictated by the enforcement of the law and tempered by the purchase price.
