This practice is useful in laboratory research on rheology of hydraulic cement systems as it has been shown to provide a paste with rheological properties similar to those obtained in a concrete from which the aggregate had been removed. Mixing of paste using C305 is not satisfactory as the paste is not thoroughly mixed, due to the absence of sand. In this practice the shear imparted to the cement paste is significantly higher than in C305 and therefore it is known as high-shear mixing.1.1 This practice covers the high-shear mixing of hydraulic cement pastes. 1.2 The values stated in SI units or inch-pound units are to be regarded as the standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This specification covers performance criteria for latexes and redispersible powders when used as modifiers in hydraulic cement concretes and mortars to improve adhesion and reduce permeability (see Note 1). Note 18212;For further information concerning theory, benefits, limitations, and applications of polymer-modified hydraulic cementitious mixtures, refer to ACI 548.3R-09. 1.2 The performance criteria are based on certain property changes that are achieved by use of the polymer modifier when compared to reference concrete or mortar (Test Methods C1439). 1.3 Prepackaged, proprietary mortar products are not included in this specification. Also, this specification covers only those materials contained in the reference or test mixtures listed in Test Methods C1439. 1.4 The values stated in SI units are to be regarded as standard. 1.5 The following precautionary statement pertains only to the test method portion, Section 10, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This specification pertains to the criteria and tests to be used for determining whether a(n) organic or inorganic processing addition, when used in the recommended amount at the option of the cement producer in the manufacture of hydraulic cements, meets the requirements as prescribed by definition in Specifications C150, C1157, C845, and C595. The materials listed in the following former ASTM Specifications shall be considered as meeting the organic processing additions requirements of this specification: C150 – 62, for Portland Cement – 58 T, for Portland Blast-Furnace Slag Cement – 58 T, for Portland Pozzolan Cement – 58, for Slag Cement 1.2 The following safety hazards caveat pertains only to the test methods described in this specification.

1.1 This specification covers cold-weather admixture systems to be added to hydraulic-cement concrete when the temperature of the concrete immediately after placement will be as low as -5.0 °C [23.0 °F] prior to the time of initial set. 1.2 This specification stipulates tests of the cold-weather admixture system with suitable materials as described in 11.1-11.3 or with materials proposed for specific work (See 11.5). Unless otherwise requested by the purchaser, tests shall be made using suitable concreting materials as described in 11.1-11.3. Note 18212;Whenever practicable, tests should be made using the concreting materials, the mixture proportions, and batching sequence proposed for the specific work (See 11.5) because the time of setting, compressive strength gain, and other properties may vary. 1.3 This specification provides three levels of testing. 1.3.1 Level 18212;During the initial approval stage, proof of compliance with the performance requirements defined in Table 1 demonstrates that the cold-weather admixture system meets the requirements of this specification. Uniformity and equivalence tests (See Section 6) shall be carried out to provide results against which later comparisons can be made. nbsp;nbsp;nbsp; 1.3.2 Level 28212;Limited retesting is described in 5.2, 5.2.1, and 5.2.2. Proof of compliance with the requirements of Table 1 demonstrates conformity of the admixture system with the requirements of this specification. 1.3.3 Level 38212;For acceptance of a lot or for measuring uniformity within or between lots, when specified by the purchaser, uniformity and equivalence tests (See Section 6) shall be used. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.5 The text of this standard references notes and footnotes, which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.6 The following precautionary caveat pertains to the test methods portion, Sections 11-18, of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. WARNINGFresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.
