| 摘要： | TRB’s National Cooperative Highway Research Program (NCHRP) has released Web-Only Document 140: Precision Estimates for AASHTO Test Methods T 186, T 154, and T 22, Determined Using CCRL Proficiency Sample Data. Web-Only Document 140 explores the precision estimates for American Association of State Highway and Transportation Officials’ Standard Test Method T 186 “Early Stiffening of Hydraulic Cement (Paste Method),” T 154 “Time of Setting of Hydraulic Cement Paste by Gillmore Needles,” and T 22 “Compressive Strength of Cylindrical Concrete Specimens.” |
