1、Designation: C 1489 01 (Reapproved 2008)1Standard Specification forLime Putty for Structural Purposes1This standard is issued under the fixed designation C 1489; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revi

2、sion. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEA units statement was added editorially as new subsection 1.2 in September 2008.1. Scope1.1 This specification covers lime putty produ

3、cts made fromhydrated lime or quicklime products. Lime putty is suitable foruse in masonry, plaster and stucco applications.1.2 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.3 This standard does not purport to address all of

8、icklime products used to makelime putty shall conform to the following chemical composi-tion requirements:Calcium and magnesium oxides (non volatile basis) 92 % min.Carbon dioxide (presoaked basis)If sample is taken at place of manufacture 5 % max.If sample is taken at other place 7 % max.4.2 Chemic

9、al composition of putty product of unknowncomposition must be determined by drying the sample in a CO2free atmosphere by a method such as Test Methods C25,Section 21, (Free Moisture in Hydrated Lime).5. Plasticity5.1 Lime putty shall have a plasticity of not less than 200Emley units when tested by t

10、he Emley method prescribed inTest Methods C110. Vicat consistency of the putty should beadjusted to a penetration of 20 6 5 mm prior to running theEmley test. If penetration results are above 25 mm, theconsistency of the putty can be increased by allowing the puttyto settle and decanting off the exc

If the penetration is below 15 mm, watershould be added to the lime putty to increase the penetration.When water is added to the putty, the putty should be mixed fora minimum of 15 s prior

12、to testing the penetration.6. Residue6.1 Residue of lime putty shall not be more than 0.5 % on a30 mesh sieve on a total putty weight basis. The residue of limeputty should be determined by the method in Test MethodsC110, Section 5, using an amount of lime putty equivalent toapproximately 100 g of s

Soaking Period7.1 Lime putty made from quicklime or hydrated lime mustbe soaked for a period of time prior to use of the product. Theactual time required to ensure complete hydration of the limeputty is dependent on the reactivit

16、y of the unhydrated oxidesused to make the putty.7.1.1 Lime putty made from quicklime must be soaked fora minimum of two weeks prior to use in construction applica-tions.7.1.2 Lime putty made with Type N hydrated lime must besoaked for at least 16 h prior to use.7.1.3 Lime putty made with Type S hyd

17、rated lime requiresenough soaking to wet the lime particles (minimum of 20min.).8. Popping and Pitting8.1 Lime putty shall show no pops or pits when tested inaccordance with the method prescribed in Test Methods C110.Vicat consistency of the lime putty should be adjusted to apenetration of 20 6 5 mm

18、 prior to running the popping andpitting test. If penetration results are above 25 mm, theconsistency of the putty can be increased by allowing the puttyto settle and decanting off the excess water or by the use of asuction pad such as the one used for the water retention test inTest Methods C110. I

19、f the penetration is below 15 mm, watershould be added to the lime putty to increase the penetration.When water is added to the putty, the putty should be mixed fora minimum of 15 s prior to testing the penetration.9. Density9.1 The wet density of the lime putty shall be no less than 80lbs/ft3and no

20、t more than 90 lbs/ft3. The density of lime puttycan be measured in the 400 ml cylindrical cup described in theApparatus Section of Test Method C 185. Care should be takenwhen placing putty in the cup to minimize the entrapment ofair. The cup should be filled in three lifts, tamping after eachlift t

21、o remove entrapped air. The top surface of the putty shouldbe struck and leveled with a metal spatula prior to weighing.The calculations used for the density determination can befound in Test Methods C110, Section 16.10. Sampling and Inspection10.1 The sampling, inspection, rejection, retesting, pac

22、kag-ing, and marking shall be conducted in accordance withPractice C50.11.
