(1) (2) Ring This shall be of those made of anti-corrosive metal having 12 mm in height, about 65 mm in inner diameter and about 2 mm in thickness, The upper and lower surfaces shall be finished in flatness and shall come in close contact with the upper and lower boards respectively. Upper Board and Lower Board These shall be of glass plates having a size of about 85 mm x 85 mm, the upper board (2) 2 mm in thickness and the lower board 3 mm therein, also free from warping strain and well kept in close contact with the ring. ( 3) Levelling Spatula Fig. 1 (3). This shall be of those having the size shown in

5 3 (4) Burette This shall be those having a content not more than 50 ml and to be used in chemical analysis. Notes (2) it makes the glass plate easily operatable to cut a notch of V-shape on the upper board beforehand. i (3) When pack the interior of anti-corrosive ring with the sample, those to be able to level1 at 4 mm in height of the sample Test Method (1) Volumetry of Rin Mount the ring approximately upon the middle of the lower boar:.and let come in close contact ( 4, with each other so as not to leak water. Fill water (at about 20%) to about fullness in the ring with a burette, cover with the upper board ( 5, and further add water until no air bubble have been seen more. Find the volume v, (mi) of ring from the reading difference of the burette. (2) Volume of Sample and Measurement of Contraction Upon the approximately middle of the lower board mount the ring, upon the lower board within the interior of ring let the sample keep well in close contact with the ring and the lower board, spread so as not to let the clearance admit thereinto, level to flatness by the use of a levelling spatula and make the thickness of the sample 4 mm. Fill up the water to about fullness in vacant portion of the ring by the use of a burette, cover ( 5, with the upper board and add water until no air bubble have been seen more in the interior. Find the poured water quantity VI (mi) from the reading the burette. Discard the poured water, remove the upper board, place three pieces of specimens within a desiccator (240 mm in diameter of middle board) of 45 k 3 % (6) humidity, let alone for 15 days and find also similarly the poured water quantity v2 (mi). Find the contraction S (%) of the sample from the following formula: where ve : volume of sample (mi) Ve (mi) = V, - VI

6 ~~~~ JIS A*575L Notes (4) At this time it is preferable to seal from the outer side of the lower board and ring with grease so as not to leak water. When covering with the upper board, carry out so as to slide upon the ring, however, never press from above the upper board. In order to maintain the humidity at 45 i 3 %, it is preferable to use saturated potassium carbonate solution. Rem ark : When the test device is weighed before and after filling the sample in the ring, the weighing of the sample enables to find the apparent specific gravity of the sample. Hereby the existence of vacant space is to be capable of being checked. Fig. 1.

(2) Lower Board The board same as the lower board for contraction test specified in (2).

7 5 (3) Filter Paper The filter paper of 11 cm diametral Class 2 specified in JIS P L, Test Method Heap the filter paper in five sheets upon a glass plate and place the ring on the approximate middle. Fill up the ring to fullness to the upper rim with the sample and level to flatness. After letting alone for 15 days measure the stains on the filter paper as follows: (1) Measure the stained width from inner periphery to outward of the ring at the quartering point including the maximum staining width and the average value (mm). (2) Count the number of sheets of oil stained paper including the filter paper being in contact with the caulking compounds. 4.4 Slump Test Devices Use the test devices as those shown in the following: (1) Channel Type Container Those made of brass sheet (about 1 mm thick) into a channel shape of 100 mm in length, 15 mm in inner width and 10 mm in depth. Polish the inner surface of the channel in finishing and let it in vertical when being loaded with the sample (see Fig. 2). (2) Cleanse the test device with Grada No. 2 in JIS K 2201 and furthermore wash it with neutral detergent. Next, wash well with water and confirm the cleanness. Fig. 2. Channel Type Container for Slump Test Unit: mm

8 JIS A*575L btI8 U Test Method So as to let the channel type container not admit air bubble, fill up the channel carefully with the sample uniformly to fullness. Suspend this for 24 h in vertical and then suspend successively for 24 h in vertical within a vessel at a temperature 30% K higher than that specified in 3.3. Express the slump value by the distance from the lower end of the container to the suspending tip in mm. 4.5 Adhesion Test Devices Use the test devices as shown in the following (1) to (3): (1) Filling Table Those as shown in Fig. 3. (2) Pulling Bed Those as shown in Fig. 4. (3) Gypsum Square Bar Mix gypsum ( ) and Toyoura standard sand for Portland cement testing at a ratio of 1 : 1 by weight, make into a gypsum mortar at a water-gypsum ratio of about 60 % and mould into a size of 18 mm x 18 mm x 130 mm. The gypsum square bar shall be dried at a temperature of about 40% to a constant weight before being used for the test. (4) Cleanse the filling table in compliance with (2). Note ( 7, To be those of Grade A specified in JIS R Test Method (1) Fill the sample up to about fullness into a joint portion (15 mm x 15 mm x 110 mm) in the filling table between the gypsum square bar and the fixing bed as shown in Fig. 3, and keep it stand for 15 days. Carry out the filling by the use of a spatula or a knife carefully so as not to let stain the upper surface of gypsum square bar. In this case, set the equipment so as to let the caulking compounds come in contact with the moulded surface side of gypsum square bar. (2) After leaving for 15 days, cutting the middle of the surface skin on the sample, if formed, slightly in the longitudinal direction with a razor or others, fit the filling table to a pulling device as shown in Fig. 4 and detach the fixing device for the gypsum square bar. In this case fit the fixing bed so as to be fixed by being engaged into the groove existing in the pulling device.

9 7 (3) Next, fit the hook as Fig. 4, pull in a distance of 15 mm and observe the state of the sample and the adhesion of it to the fixing bed as well as to the gypsum square bar. Consider those free from breaking-off of adhesive surface and sample to be accepted. Note Remark: Consider the standard required time to be 20 sec. Care should be taken on use when there is seeping of oil of not less than 5 mm from the contact surface of sample to gypsum square bar. Fig. 3. Filling Table for Adhesion Test Unit: mm

(2) Penetrometer This shall be the penetrometer and needle specified in JIS K (3) Gypsum Square Bar This shall be moulded in similar manner to the gypsum square bar specified in (3). Provided that the size shall be considered to be 20 mm x 40 mm x 100 mm Test Method (1) Fill the sample into the caulking compound filling part (15 mm x 40 mm x 95 mm) of the filling device shown in Fig. 5 to about fullness. Carry out the filling by the use of a spatula or knife carefully enough so as not to let air bubbles admit therein.

11 9 (2) Next, after standing still for about 24 h, remove surface skin produced, if any, let the needle or penetration measurement penetrate for 5 sec. at the falling gross weight of 12.5 g along the joint centre, and measure the said penetration quantity up to 0.1 mm by means of a penetrometer. Carry out the measurement three times and find the average value Pl. Wipe the needle at every time of measurement with a soft cloth saturated with a small quantity of industrial gasoline specified in (2) and further wipe with a dry soft cloth to use. (3) Level the surface of the sample, let alone for 14 continuous days, remove the surface skin produced, if any, and find the average penetration quantity Ps in the same method as (2). (4) Find the hardening rate from the following formula: Hardening rate (%) = V X 100 Remark: In case where the measured value is strikingly changing, there is possibly the case of vacant space existing in the sample. In such a case re-test may be carried out. Fig. 5. Filling Device Unit: mm Gypsum square bar Space to be filled with caulking compounds Space to be filled with caulking compounds

12 JIS A* OU03383 O Cracks Before pulling in the adhesion test and before removing the surface skin in the hardening rate test, observe with the naked eye the existence of surface cracks also the existence of stripping in the adhesive portion. At this time accept the case where no crack and stripping are.produced. 4.8 Alkali Resistance Test Devices Use the test devices as shown in the following (1) Polyethylene Beaker content. This shall be of those having 300 ml Test Tube This shall be of those about 15 mm in outer diameter and 105 mm in length. Test Method Wash well the outer surface of a test tube with a hanger at the top as shown in Fig. 6, dry and then apply the sample in a thickness of about 3 mm as shown in Fig. 6. Pour about 300 ml of saturated calcium hydroxide solution of Grade 1 specified in JIS K 8575 into a polyethylene beaker and hereinto hang the test tube in the approximate middle of the beaker so as to let the lower sample immerse by 3 cm into the solution. After being immersed for 15 days, cut the sample to strip off and observe the adhesivity to the glass. Accept the case where there is no difference between the adhesivities of the upper and lower samples seen. Remark: In case where no alkali resistance is especially needed, the test may be omitted.
