1、Designation: C 1059 99Standard Specification forLatex Agents for Bonding Fresh To Hardened Concrete1This standard is issued under the fixed designation C 1059; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revisi
2、on. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers latex bonding agents, suitablefor brush, broom, or spray application, to bond fresh concreteto hardene
3、d concrete.1.2 These bonding agents are intended for bonding newconcrete to old concrete such as interior surfaces, floors,roadways, bridge decks, ramps, runways, walks, and curbs.1.3 The values stated in either inch-pound units or SI unitsshall be regarded separately as standard. Within the text, t
4、he SIunits are shown in brackets. The values stated in each systemmay not be exact equivalents, therefore, each system must beused independently of the other without combining values inany way.2.

Classification and Use3.1 This specification provides for the classification of thelatex bonding agents in accordance with use.3.1.1 Type I (Redispersable), is restricted for use in interiorwork not subject to water immersion or high humidity.3.1.2 Type II (Non-redispersable), may be used
6、for areassubject to high humidity or immersion in water and is suitablefor use in other areas.4. Ordering Information4.1 Purchase orders for these materials shall identify:4.1.1 The number of this specification and the required type,and4.1.2 Supplementary requirements if necessary.5. Physical Proper
7、ties5.1 The material shall conform to the requirements of Table1 when tested in accordance with Test Method C 1042.6. Sampling6.1 For sampling of bulk quantities, a batch or lot shall beconsidered a unit of manufacture as prepared for shipment ormay consist of a blend of two or more production runs
8、ofmaterial. A composite sample shall be taken and it shallprovide a volume of at least 1 gal 4 L.6.2 When the bonding agent to be sampled is in containers,the sample shall be obtained by taking a portion out of thecontainers that is equal in number to the next integer largerthan the cube root of the
9、 total number of containers in the lot.Grab samples shall be taken from each container and they shallhave a volume of at least12 pt. 0.25 L.6.3 All the sample containers shall be sealed to preventleakage or dilution and shall be properly marked for identifi-cation and correlation.7. Rejection7.1 The
10、 purchaser has the right to reject the bonding agentif it fails to meet the bond strength requirement, appearscurdled or otherwise nonuniform, or if it has a rank odor.8. Packaging and Package Marking8.1 The proprietary name and type of the organic bondingagent and the net quantity in gallons or lit
11、res shall be plainlymarked on the containers in which the material is delivered.Similar information shall be provided in the shipping advicesaccompanying packaged or bulk shipments of admixtures.9.
