CONCRETE QUALITY ASSURANCE USING ACCELERATED STRENGTH TESTING
This report provides additional information and guidance to division laboratories and field offices within the Corps of Engineers on the use of accelerated strength testing for predicting potential compressive strengths of concrete and assuring the quality of concrete production. Emphasis is placed on the use of ACI Standard 214 for interpreting accelerated strength test results. The report concludes that accelerated strength testing can apparently predict concrete potoential compressive strengths and assure proper quality control of concrete production if a valid regression equation is developed. The regression equation may be developed from laboratory or field test data. The regression analysis should use a minimum of 30 sets of test data which have a broad strength range. If project materials change during the course of construction, a new linear regression analysis must be performed using compressive strength data representing concrete made from the new materials. Additional investigative studies involving compressive strength test data for future projects are recommended to determine if additional guidance on the use of accelerated strength testing is needed.
