1、Designation: C 1159 98 (Reapproved 2003)Standard Specification forSulfur Polymer Cement and Sulfur Modifier for Use inChemical-Resistant, Rigid Sulfur Concrete1This standard is issued under the fixed designation C 1159; the number immediately following the designation indicates the year oforiginal a
2、doption or, in the case of revision, the year of last revision. 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 the requirements for sulfurpolymer cement
3、and sulfur modifier for use in rapid setting andhigh strength applications of chemical-resistant sulfur con-crete.1.2 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are providedfor information only.1.3 This standard does not purport to addres

6、nitions of terms used in this speci-fication, see Terminology C 904.4. Types and Composition of Sulfur Concretes4.1 There are currently two types of commercial sulfurconcrete technology in use. Both utilize cyclopentadiene-typehydrocarbons reacted polymerically with sulfur, but the sulfurconcrete pr
7、oduction processes differ. Each technology is de-scribed further in 4.1.1 and 4.1.2.4.1.1 Type 1Type 1 sulfur concrete uses sulfur polymercement made by reacting a blend of dicyclopentadiene andoligomers of cyclopentadiene with sulfur. The sulfur polymercement shall conform to the chemical and physi
8、cal require-ments prescribed in Table 1.4.1.2 Type 2Type 2 sulfur concrete uses a sulfur modifiermade by reacting sulfur with an oligomeric polymer ofcyclopentadiene. The sulfur modifier shall conform to thechemical and physical requirements prescribed in Table 2. Thesulfur modifier is mixed with el

Physical Properties5.1 Particles of sulfur polymer cement and sulfur modifiershall be small enough (generally less than in. nominal size)to melt efficiently when exposed to heated aggregate whileminimizing the amount of dust part
10、icles (generally less than 74m) to reduce potential dust hazards.6. Methods of Sampling and Testing6.1 Sulfur polymer cement and sulfur modifier shall besampled and tested to determine the properties enumerated inthis specification in accordance with the following methods:6.1.1 SamplingWhen the purc
11、haser desires that the sulfurpolymer cement or sulfur modifier be sampled and tested toverify compliance with this specification, every precautionshall be taken to obtain representative random samples that willshow the true nature and condition of the material. Samplesshall be taken to represent as
12、nearly as possible an average ofthe bulk material sampled or to ascertain the maximumvariation in characteristics which the material possesses.6.1.2 Sulfur and carbon contents shall be determined bycombustion of a small sample of sulfur polymer cement orsulfur modifier using carbon/sulfur analyzing
13、equipment. Typi-cal equipment is that used for analyzing coal samples.6.1.3 Hydrogen content shall be determined by combustionof a small sample of sulfur polymer cement or sulfur modifierin an oxygen environment converting the hydrogen to watervapor measured using gravimetric procedures by absorptio
