ASTM C150/C150M-15 pdf free.Standard Specification for Portland Cement.
1.1 This specification covers ten types of portland cement, as follows (see Note 2):
1.1.1 Type I—For use when the special properties specified for any other type are not required.
1.1.2 Type IA—Air-entraining cement for the same uses as Type I, where air-entrainment is desired.
1.1.3 Type II—For general use, more especially when moderate sulfate resistance is desired.
1.1.4 Type IIA—Air-entraining cement for the same uses as Type II, where air-entrainment is desired.
1.1.5 Type II(MH)—For general use, more especially when moderate heat of hydration and moderate sulfate resistance are desired.
1.1.6 Type II(MH)A—Air-entraining cement for the same uses as Type II(MH), where air-entrainment is desired.
1.1.7 Type III—For use when high early strength is desired.
1.1.8 Type IIIA—Air-entraining cement for the same use as Type III, where air-entrainment is desired.
1.1.9 Type IV—For use when a low heat of hydration is desired.
1.1.10 Type V—For use when high sulfate resistance is desired.
5. Ingredients
5.1 The cement covered by this specification shall contain no ingredients except as follows:
5.1.1 Portland cement clinker.
5.1.2 Water or calcium sulfate, or both. The amounts shall be such that the limits shown in Table 1 for sulfur trioxide and loss-on-ignition are not exceeded.
5.1.3 Limestone. The amount shall not be more than 5.0 % by mass such that the chemical and physical requirements of this standard are met (see Note 3). The limestone, defined in Terminology C5 1, shall be naturally occurring and consist of at least 70 % by mass of one or more of the mineral forms of calcium carbonate.
Nom 3—The standard permits up to 5 % by mass of the final cement product to be naturally occurring, finely ground limestone, but does not require that limestone be added to the cement. Cement without ground limestone can be specified in the contract or order.
6. Chemical Composition
(. I Portland cement of each of the ten types shown in Section 1 shall coniorm to the respective standard chemical requirements prescribed in Table 1. lii addition, optional chemical requirements are shown in Table 2.
Nom 5—The limit on the sum. C3S + 4.75CA. in Table I provides control on the heat of hydration of the cement and is consistent with a ‘lest Mcthi Cl 86 scvcn-dav hcdl of hydriioii limit of 335 LJ(kg 180 calfgl. or a Test Method C1702 three-day heat of hydration limit of 315 kilkg 175 cal/gI.
NOTE 6—There are cases where performance of a cement is improved with 5O in excess of the Table I limits in this specitication. Test MethxI C563 is one of several methods a manufacturer can usc to evaluate the effect of sultate content on cement characteristics. Whenever SO1 content of a celilerit ecccds T4bIe I limits, Test Method C 1038 results provide evidence that excessive expansion (toes not occur at this higher sulfate content.
7. Physical Properties
7.1 Portland cement of each of the tcn types shown in Section 1 shall conform to the respective standard physical requirements prescribed in Table 3. In addition, optional physical requirements are shown in Table 4.
8. Sampling
. I When the purchaser desires that the cement he sampled and tested to verify compliance with this specification, perform sampling and testing in accordance with Practice C 183.ASTM C150/C150M-15 pdf free download.
