32、-resistant materials are to be exposed in service.7. Test Specimens7.1 The number of specimens required is dependent uponthe number of test media to be employed, the number ofdifferent temperatures at which testing is performed, and thefrequency of test intervals. The test specimens shall consist of
33、sets of a minimum of three cylinders for one medium at asingle temperature and for each test interval. In addition one setof at least three specimens shall be available for test immedi-ately following the conditioning period, and other sets of atleast three, equivalent to the number of test temperat
34、ures, forthe total test period. Calculate the total number of specimensrequired as follows:N 5 nM 3T 3I!1nT1n (1)where:N = number of specimens,n = number of specimens for a single test,M = number of media,T = number of test temperatures, andI = number of test intervals.NOTE 3For calcium aluminate ce
35、ments, strength and weight changesare a natural phenomena, with the degree of change being dependent uponthe test conditions involved. Therefore, when conducting chemical resis-tance tests on these products, additional sets of control samples should beprepared for testing at each test temperature an
36、d each test interval. Theimmersion medium for these control samples will be potable water.7.2 Make all specimens for a single determination from asingle mix.7.3 Test Method APrepare test specimens to be used inaccordance with Test Method A as described in 8.1.

If the faces of the specimen are not flat, smooth, andnormal to the cylinder axis, they may be sanded, ground, ormachined to specification. Exercise care that the frictional heatdeveloped during such op
38、erations does not damage the speci-mens.7.4 Test Method BPrepare test specimens to be used inaccordance with Test Method B as described in 8.1.

Preparation of Specimens8.1 Specimen Preparation for Test Methods
42、 A and B:8.1.1 Resin, Silicate, and Silica MaterialsMix a sufficientamount of the components in the proportions and in the mannerspecified by the manufacturer of the materials. Fill the moldsone-half full. Remove any entrapped air by using a cutting andstabbing motion with a spatula or rounded-end r
43、od. Fill theremainder of the mold, working down into the previouslyplaced portion. Upon completion of the filling operation, thetops of the specimens should extend slightly above the tops ofthe molds. When the molds have been filled, strike off theexcess material, even with the top of the mold. Perm
44、it thematerial to remain in the mold until it has set sufficiently toallow removal without danger of deformation or breakage.8.1.1.1 Silicate MaterialsSome silicates may require cov-ering during the curing period. After removal from the molds,acid-treat the specimens, if required, in accordance with
45、 therecommendations given by the manufacturer. No other treat-ment shall be permitted. Record the method of treatment in13.1.3.8.1.2 Sulfur Materials:8.1.2.1 Sulfur MortarsSlowly melt a minimum of 2 lb(900 g) of the material in a suitable container at a temperatureof 265 to 290F (130 to 145C) with c
46、onstant agitation. Stir tolift and blend the aggregate without beating air into the melt.Place the piece of plastic sheet containing the14-in. (6-mm)round hole over the open face of the mold with the holecentered on the face. On top of the piece of plastic sheet andsurrounding the hole, place a sect
47、ion of plastic tubing or pipe1 in. (25 mm) in diameter by 1 in. high. Pour the meltedmaterial through the hole into the mold and continue to pouruntil the section of tubing or pipe is completely filled. Theexcess material contained in the hole in the plastic sheet acts asa reservoir to compensate fo
48、r shrinkage of the material duringcooling. Allow the specimen to remain in the mold until it hascompletely solidified. Upon removal, file, grind, or sand thesurface flush, removing the excess material remaining at thepouring gate.8.1.2.2 Sulfur Polymer Cement ConcretesPrepare speci-mens in accordanc
