"Recommended Practice for Evaluation of Strength Test Results of Concrete (ACI 214-77)." 14 pp.; $5.00 to ACI members, $8.50 to non-members; postage and handling fee $1.50. American Concrete Institute, P.O. Box 19150 Redford Station, Detroit, Mich. 48219.
This new ACI standard, ACI 214-77, supersedes ACI 214-65. It discusses the numerous variations that occur in the strength of concrete and presents statistical procedures which are useful in interpreting these variations.
One important change in the new standard involves Table 3.5, "Standards of Concrete Control." The overall variation of concrete is now expressed both in terms of standard deviation and coefficient of variations.
Covered in the new report are: variations in strength, including properties of concrete and testing methods; analysis of strength data, including statistical functions, strength variations and standards of control, and criteria for strength requirements, quality control charts, tests and specimens required, and rejection of doubtful specimens.
