39、mine the net mass of concrete in the package (or packages), then empty into a clean, watertight container.3Specifications, Tolerances, and Other Technical Requirements of Weighing and Measuring Devices, Handbook 44, National Bureau of Standards.C387/C387M 11b314.2 Mix the concrete, determine the pro

40、perties of the fresh concrete, and mold and cure the specimens in accordance with theapplicable provisions of Practice C192/C192M, or modifications of them as outlined herein. Test the strength of the concrete inaccordance with Test Method C39/C39M.14.3 Mix the entire sample of the combined, dry mat

41、erial for concrete either by hand or by machine, except that hand mixingis not applicable to air-entrained concrete. Add mixing water in sufficient amount to produce a slump of 50 to 75 mm 2 to 3 in.14.4 Use a watertight, clean metal container for hand mixing, using either a blunted bricklayers trow

42、el, hands protected byrubber gloves, or a shovel, whichever is more convenient. Mix the dry batch until the materials appear to be uniformly distributed.Add water while mixing until the concrete is homogeneous in appearance and has the desired slump. If prolonged mixing isrequired because of the add

43、ition of mixing water in increments while adjusting the slump, the batch must be discarded and a newbatch made without interrupting the mixing to make trial slump tests.14.5 Place all materials in the mixer to be used for machine mixing.Amixing period of 3 min followed by a 3-min rest, followedby 2-

44、min final mixing is suggested, unless a different procedure is better adapted to the mixer being used. Cover the open end ofthe mixer during the rest period to reduce evaporation. Test the slump in accordance with Test Method C143/C143M uponcompletion of the mixing. If the slump test of the mixed ba

45、tch shows that additional water is required, return the sample used forthe slump test promptly to the mixer, add additional water, and remix the batch for 2 min. Retest the slump. If the slump is notfrom 50 to 75 mm 2 to 3 in., discard the batch.14.6 Discharge the mixed batch into a clean, watertigh

46、t container that has been predampened, then remix the batch by hand,using a scoop or trowel, until the batch appears to be uniform. Promptly determine the density in kilograms per cubic meter (orpound per cubic foot) in accordance with Test Method C138/C138M. Return samples used for the slump and un

47、it weight test tothe container, then remix the batch by hand and mold the specimens.14.7 Mold six cylinders from each batch, using three cylinders for test at 7 days and three at 28 days, except that in the caseof high early strength concrete, three cylinders shall be tested at 3 days and three at 7

48、 days. Compression test specimens shall becylindrical with a length equal to twice the diameter. The minimum specimen diameter shall be 75 mm 3 in., but the maximumdiameter is not limited, provided the number of specimens for a test as required in this section are molded from a single batch andthe s

49、ample taken in accordance with 13.1. For acceptance, the average of the strengths of the three specimens tested at each ageshall not be less than the compressive strength required in Table 1 for the type of concrete under test and no individual specimenshall have a strength less than 90 % of the required strength.14.8 The report of the tests of the concrete shall include the following:14.8.1 Net mass of dry, combined material in the bag or bags determined by subtracting the mass of the empty bag or bags fromthe gross mass
