Concrete used in performing air content test shall not be used in fabricating test <br /> specimens. <br /> D. Mark each test cylinder with job name,Contractor's name,mix number,date,location of <br /> pour and measured slump. In addition, mark measured air content when air-entraining <br /> admixture is specified. <br /> E. ITL shall submit copies of test results to Owner,Architect and Contractor as soon as <br /> practicable after they are made. <br /> 3.8 EVALUATION OF TEST RESULTS AND FAILURE TO MEET STRENGTH <br /> REQUIREMENTS <br /> A. Test results: Evaluate in accordance with ACI 214. <br /> B. Evaluations shall be valid only if samples have been taken and tests have been conducted <br /> in accordance with ACI and ASTM specifications and methods as applicable. <br /> C. If strength tests performed on concrete cylinders,cast at time concrete is placed,fail to <br /> meet specified 28 day values,or if samples have not been taken and tests conducted as <br /> specified,concrete represented by such samples and tests shall be considered questionable <br /> and shall be subject to further testing at expense of Contractor. <br /> D. These additional tests of questionable concrete shall be performed by Independent Testing <br /> Laboratory, acceptable to Architect,and shall be conducted in accordance with ASTM <br /> C42. Concrete cores may be obtained in field,or load tests conducted and results <br /> evaluated in accordance with ACI 318,Chapter 20. <br /> E. Test results obtained by use of impact hammer or sonoscope,unless correlated with other <br /> data,will not be considered conclusive in evaluating strengths of concrete. <br /> F. If additional testing fails to demonstrate strengths adequate for intended purpose of <br /> member or members in question,as determined by Architect,remove questionable <br /> concrete and replace with concrete meeting specifications. <br /> END OF SECTION <br /> ADDENDUM#1 <br /> 1607.001 -ORONO ICE ARENA (CP-2) Page 03300 - 13 <br />
