Method of Test for Flexural Strength of Concrete (Using Simple WSDOT Beam with Center-Point Loading) T 802 Are statistically analyzed flexural strength results for five 14 – day beams shown on the mix design? Flexural strength should be 5-05.3(1) equal to or greater than 650 psi. 5-05.3(1), Is the quality level of the beam specimens greater than 80%? 1-06.2(2)D WSDOT FOP Compressive Strength of Cylindrical Concrete Specimens. for AASHTO T 22 Are the results of five sets of 28 day compressive strength 5-05.3(1) cylinders provided? Does the compressive strength data indicate average compressive 5-05.3(1), strength of 4000 psi or greater? 5-05.3(4)A WSDOT FOP Air Content of Freshly Mixed Concrete by the Pressure Method for WAQTC T 152 Does the mix design indicate air content between 3 7%? 5-05.3(4)A – ASR Mitigation Section 9-03.1(1) If the ASA database indicates Mitigation Required” and the ASR 14 Day test results is 0.21 to 0.45% the “ASR – design must include at one of the following: Low Alkali Cement per Section 9-01.2(3).
