1、Designation: C 150 07Standard Specification forPortland Cement1This standard is issued under the fixed designation C 150; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates
2、the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers eight types of portland cement,as follows (see Note 2):1.1
3、.1 Type IFor use when the special properties specifiedfor any other type are not required.1.1.2 Type IAAir-entraining cement for the same uses asType I, where air-entrainment is desired.1.1.3 Type IIFor general use, more especially when mod-erate sulfate resistance or moderate heat of hydration isde
4、sired.1.1.4 Type IIAAir-entraining cement for the same uses asType II, where air-entrainment is desired.1.1.5 Type IIIFor use when high early strength is desired.1.1.6 Type IIIAAir-entraining cement for the same use asType III, where air-entrainment is desired.1.1.7 Type IVFor use when a low heat of
5、 hydration isdesired.1.1.8 Type VFor use when high sulfate resistance isdesired.NOTE 1Some cements are designated with a combined type classifi-cation, such as Type I/II, indicating that the cement meets the require-ments of the indicated types and is being offered as suitable for use wheneither typ
6、e is desired.NOTE 2Cement conforming to the requirements for all types are notcarried in stock in some areas. In advance of specifying the use of cementother than Type I, determine whether the proposed type of cement is, orcan be made, available.1.2 When both SI and inch-pound units are present, the
7、 SIunits are the standard. The inch-pound units are approxima-tions listed for information only.1.3 The text of this standard references notes and footnoteswhich provide explanatory material.

44、uirements of this specification.11.2 At the option of the purchaser, retest, before using,cement remaining in bulk storage for more than 6 months orcement in bags in local storage in the custody of a vendor formore than 3 months after completion of tests and reject thecement if it fails to conform t

46、hall be rejected and if theaverage mass of packages in any shipment, as shown bydetermining the mass of 50 packages selected at random, is lessthan that marked on the packages, the entire shipment shall berejected.12. Manufacturers Statement12.1 At the request of the purchaser, the manufacturer shal
47、lstate in writing the nature, amount, and identity of anyair-entraining addition and of any processing addition used,and also, if requested, shall supply test data showing compli-ance of such air-entraining addition with Specification C 226and of such processing addition with Specification C 465.12.
48、2 When limestone is used, the manufacturer shall state inwriting the amount thereof and, if requested by the purchaser,shall supply comparative test data on chemical and physicalproperties of the cement with and without the limestone (SeeNote 5). The comparative tests do not supersede the normaltest
49、ing to confirm that the cement meets chemical and physicalrequirements of this standard. The amount of limestone incement shall be determined in accordance with Annex A2.NOTE 5Comparative test data may be from qualification tests per-formed by the manufacturer during formulation of the cement withlimestone.13.
