    1、Designation: C 399 98 (Reapproved 2008)e1Standard Practice forUse of Chemical-Resistant Resin Mortars1This standard is issued under the fixed designation C 399; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revis

    2、ion. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.e1NOTEA warning note was editorially corrected in July 2008.1. Scope1.1 This practice provides information on the handling andproper use of

    3、chemical-resistant resin mortars such as thosecovered in Specification C 395.NOTE 1Resin mortars and grouts are differentiated as follows: resingrouts are applied to the joints, generally14 in. (6 mm) wide, after thebrick or tile are set in place (grouting or tile setters method). Resinmortars are t

    4、roweled onto the brick or tile, generally in a18 in. (3 mm)thickness, before the brick are laid in place (buttering or bricklayersmethod). Refer to Practice C 723.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to S

    5、I units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and deter

    6、mine the applica-bility of regulatory limitations prior to use. Specific precau-tions are given in Sections 5 and 5.2.2.

Storage4.1 When stated on the package, the manufacturers recom-mendations shall be followed. In all cases, storage shall be ina dr

    9、y place with containers tightly closed and away from openflames. Some resins should be stored in a cool place attemperatures as low as 40 to 50F (5 to 10C) to extend theirshelf life. Powder or resin that has become wet or otherwisecontaminated shall not be used.5. Hazards5.1 Consult manufacturers Ma

(WarningOpen flames must be kept from the area.“No Smoking” signs should be posted.)6. Equipment6.1 For hand mixing, a shallow mortar box shou

    11、ld beprovided. A suggested size is 2 ft2by 4 in. (600 mm2by 100mm) deep.6.2 Equipment for power-mixing ranges from small mixers,such as described in Practice C 305, to simple beaters used onlow-speed motors. A suitable container is a round-bottom panor a 5-gal (20-L) pail, which is commonly availabl

    12、e.6.3 Equipment may be required for heating or coolingmaterials as conditions dictate.6.4 All mixing equipment should be clean and dry.7. Mixing7.1 For hand mixing, measure the liquid into the mortar box,then stir the powder in gradually, working out all lumps and airbubbles. Mix with a masons trowe

    13、l or other suitable tool.1This practice is under the jurisdiction of ASTM Committee C03 on Chemical-Resistant Nonmetallic Materials and is the direct responsibility of SubcommitteeC03.02 on Monolithics, Grouts and Polymer Concretes.Current edition approved June 1, 2008. Published July 2008. Original

    14、ly approvedin 1957. Last previous edition approved in 2003 as C 399 98 (2003).2For referenced ASTM standards, visit the ASTM website, www.astm.org, orcontact ASTM Customer Serivce at serviceastm.org. For Annual Book of ASTMStandards volume information, refer to the standards Document Summary page on

    15、the ASTM website.1Copyright ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959, United States.7.2 For power mixing, measure the liquid into the containerand mix in the powder gradually and uniformly.7.3 Mortars shall be mixed in accordance with the manu-facturer

    16、s specifications. It is recommended that some meansof measuring be devised so that the batches are uniform.Simple volume measurements may be used, but weighing ispreferred. Consult the manufacturer if variations in proportionsare being considered.7.4 Batch size should be varied according to temperat

    17、ure. Inhot weather, batches may be as small as 10 lb (5 kg), and incold weather they may be increased to as much as 50 lb (23kg).7.5 No additives such as sand, portland cement, or watershould be added.7.6 Containers of resins and powders should be closed whennot being used.8. Handling8.1 Resin morta

    18、rs cure very slowly at low temperatures. Ifwork must be carried on at temperatures below 60F (16C),chemical-resistant construction units should be heated and thearea enclosed and heated to obtain proper cure. However,certain resin mortars can be used satisfactorily at lowertemperatures.8.2 Mortar sh

    19、ould be transferred immediately from themixing vessel and spread in a thin layer on the mortar pan, asmortar heats up during setting and thick layers or large massesretain this heat. Retained heat shortens the working time.8.3 Mixed mortar that has become unworkable shall not beretempered with resin

    20、 liquid but shall be discarded.8.4 When resin mortars are to be exposed to temperaturesbelow 60F (16C) or above 90F (32C) during mixing,application, or setting, special precautions are required. Themanufacturer should be consulted for recommendations.9. Laying Chemical-Resistant Brick or Tile9.1 Bri

    21、ck and tile are covered by Specifications C 279,C 410, and C 980.9.2 The brick or tile shall be dry. Minimum and maximumtemperature of the brick or tile at the time of use shall be 50 to90F (10 to 32C). Sufficient time is required to establishtemperature equilibrium within the brick or tile.9.3 Wall

    22、s with No Sulfur Back-JointSpread a bed-joint ofmortar the width of the brick or tile and14 to38 in. (6 to 10mm) thick. Butter one end and the back side of each brick ortile with approximately14 in. (6 mm) thickness of mortar.Press the brick or tile into the bed and against the wall andadjacent unit

    23、 until the joint in each is as near to18 in. (3 mm)thick as good workmanship will permit. Trim off excess mortarand return it to the mortar board.9.4 Walls with Sulfur Back-JointSpread a bed-joint asdescribed in 9.3. Butter one end of each brick or tile and lay it14 in. (6 mm) away from the wall. Af

    24、ter each course has beenlaid, pour the back-joint with molten sulfur cement in accor-dance with the Practice C 386.9.5 Floors With Bed-JointSpread the mortar on the floorto approximately18-in. (3-mm) thickness. Spread approxi-mately14 in. (6 mm) thickness of mortar on two adjacent edgesof the brick

    25、or tile. Press into the bed and against the startingcurb or brick until the joint is as near to18 in. (3 mm) thick asgood workmanship will permit. Trim off the excess mortar andreturn it to the mortar board.10. Cleaning Mortar From Chemical-Resistant Brick orTile10.1 Various compounds and applicatio

    26、n methods are avail-able from mortar manufacturers for masking brick or tile tokeep mortar from adhering to them. Such compounds may beremoved by steam or water after the joints have hardened.10.2 The manufacturer of the mortar should be consulted forthe method of cleaning mortar from the face of th

    27、e brick or tilebefore hardening, since the cure of certain mortars is affectedby contact with water.11. Cleaning the Equipment11.1 Clean equipment according to manufacturers recom-mendations. Remove hardened mortars from metal equipmentby sandblasting. Most solvents used for cleaning are flam-mable,

    28、 and therefore precautions should be taken. (Warning,see 1.3 and 5.2.)12. Curing12.1 Resin mortars are generally formulated to cure readyfor use in 24 to 48 h at normal temperatures. The manufacturershould be consulted for details.12.2 Methods are available for speeding the cure of resinmortars. Con

    29、sult the manufacturer for details.12.3 The construction should be protected from weather andwater, and from mechanical damage until the mortar is cured.13.
