(25
17、6 0.8 mm) in diameter by 1 6 132 in. (25 6 0.8mm) high. The molds may be constructed in any manner that will allow formation of a test specimen of the desired size. Typicalmolds may consist of a 1 in. thick flat plastic sheet in which 1 in. diameter, smooth-sided holes have been cut, and to the bott
18、omof which a 14 in. (6 mm) thick flat plastic sheet (without matching holes), is attached by means of screws or bolts. Alternatively,the molds may consist of sections of round plastic tubing or pipe, 1 in. in inside diameter and 1 in. long, having sufficient wallthickness to be rigid and retain dime
19、nsional stability during the molding operation, and a 14 in. thick flat plastic sheet on whichone open end of each section can be rested. With the latter style of mold, the tubing segment may be sealed with a material suchas caulking compound or stopcock grease. For most types of specimens it is sat
20、isfactory to simply seal one end of the tubingsegment with strips of 2 in. wide masking tape.NOTE 1For use with sulfur materials, an additional piece of flat plastic sheet at least 18 in. (3 mm) thick containing a 14 in. (6 mm) hole and a sectionof plastic tubing 1 in. (25 mm) in diameter by 1 in. h
21、igh are required. They are used to form a pouring gate and reservoir in the preparation of sulfurmaterial specimens.5.5.2 Mold Method BMolds for the 2 in. (50 mm) cube specimens shall be tight fitting and leakproof. The parts of the molds,when assembled, shall be positively held together. The molds
22、shall be made of metal not attacked by the material. The sides ofthe molds shall be sufficiently rigid to prevent spreading or warping. The interior faces of the molds shall be manufactured toensure plane surfaces with a permissible variation of 0.002 in. (0.05 mm). The distances between opposite fa
23、ces shall be 2 6 116in. (50 6 0.8 mm). The height of the molds, measured separately for each cube compartment, shall be 2 6 116 in. The anglebetween adjacent interior faces and top and bottom planes of the mold shall be 90 6 0.5 measured at points slightly removed fromthe intersection of the faces.5
24、.5.3 Mold Method CMolds shall be right cylinders made of heavy gage metal or other nonabsorbent material. The cylinderdiameter shall be at least four times the nominal maximum aggregate size in the mix. The minimum cylinder diameter shall be2 in. (50 mm). The cylinder height shall be two times the d
