1. Scope

A5-1.1

This Standard addresses the definition of Portland cement; the chemical, physical, and uniformity requirements; the tests required; the procedures for inspection and sampling; the units of measurement, packaging, marking, and storage.

1.2

Types The five types of Portland cement covered in this Standard are identified as follows: (Type - Name) 10 - Normal Portland cement; 20 - Moderate Portland cement ( Moderate with respect to the heat of hydration or sulphate resistance.); 30 - High-early-strength Portland cement; 40 - Low-heat of hydration Portland cement; 50 - Sulphate-resistant Portland cement.

Note: The requirements of this Standard also apply to white Portland cement.

A8-1.1

This Standard addresses the requirements for two types of ma sonry cement for use in masonry mortar; Types N and S.

A23.5-1.1

This Standard addresses the requirements for supplementary cementing materials consisting of natural pozzolans, fly ash, ground granulated slag, and silica fume, added at the mixing plant to supplement the Portland cement in concrete.

1.2

This Standard provides for the acceptance of a supplementary cementing material either on the basis of tests on samples of a single lot or on the basis of test records of the source.

1.3

This Standard also addresses preblending of specific supplementary cementing materials as defined under Clause 3.

A362-1.1

General This Standard addresses the definition of blended hydraulic cement; its chemical and physical requirements; the tests required; the procedures for inspection and sampling; the units of measurement; and its packaging, marking, and storage. The intent of this Standard is to define the properties of the blended product; it does not include cases in which the supplementary cementing material is stored, weighed, and batched separ ately from the cement in the concrete mix at a concrete production facility or at a job site.

1.2 1.2.1 Basic Types The four types of blended hydraulic cement addressed in this Standard are (a) Portland blast furnace slag cement (S); (b) Portland flyash cement (F); (c) Portland silica fume cement (SF); and (d) ternary blend cement.

1.2.2

Nomenclature The naming practice is as follows: TE-A/B, where T = the equivalent performance to Type 10, 20, 30, 40, or 50 Portland cement; E = an indication that the cement has equivalent performance for the properties stipulated in Table 2; A = the predominant supplementary material; and B = the secondary supplementary material, only specified in a ternary blend.

Examples: 10E-S - a Portland blast furnace slag cement having equivalent perform ance to that of a Type 10 Portland Cement. 40E-F - a Portland flyash cement having equivalent performance to that of a type 40 Portland cement; and 50E-S/SF - a ternary blend cement having equivalent performance to that of a Type 50 Portland cement with slag being the predominant supplementary cementing material and silica fume the secondary supplementary cementing material. Note: Blended hydraulic cement may develop lower early compressive strengths than the corresponding Portland cement. This effect is more pronounced as the proportion of slag or fly ash is increased. When a Portland silica fume cement is used, experience indicates that early strengths are frequently higher than the strength of the corresponding Portland cement.

A363-1.1

This Standard addresses the physical and chemical requirements for cementitious hydraulic slag.

A456.1-1.1

General Test methods in this Standard address the chemical analysis of hydraulic cement and supplementary cementing materials. At the discretion of the laboratory, alternative methods demonstrated to be of acceptable precision and bias that further satisfy the qualification criteria of Clause 3 may be used for analysis.

1.2

Test Frequencies Refer to Table 1 of CSA Standard A456.2-A1 for frequencies of chemical testing.

A456.2-1.1
