(It includes GI's 2 and 3.)
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.
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.
This Standard addresses the requirements for two types of masonry cement for use in masonry mortar; Types N and S.
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.
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.
This Standard also addresses preblending of specific supplementary cementing materials as defined under Clause 3.
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 separately from the cement in the concrete mix at a concrete production facility or at a job site.
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.
The naming practice is as follows:
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.
10E-S - a Portland blast furnace slag cement having equivalent performance 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.
This Standard addresses the physical and chemical requirements for cementitious hydraulic slag.
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.
Refer to Table 1 of CSA Standard A456.2-A1 for frequencies of chemical testing.
This Standard sets out the various physical test methods for hydraulic cements, supplementary cementing materials, and cementitious hydraulic slag. It is divided into test methods and standard practices numbered A1 to A6, B1 to B7, and C1 to C8, representing dry tests, paste tests, and mortar tests, respectively. Each test method or standard practice contains a scope, referenced documents, summary of test, equipment and materials, and test procedure. The test methods are in the following order:
A1 Standard Practice for Sampling, Testing, and Inspection;
A2 Test Method for Determination of Density of Cement;
A3 Test Method for Determination of Cement Fineness by Wet-Sieving;
A4 Glass Content by the Modified McMaster Method;
A5 Rapid Test Method for Determining the Tendency of Silica Fume to Entrap Air in Mortar or Concrete;
A6 Test Method for Verification of Sand;
B1 Standard Practice for Mechanical Mixing of Hydraulic Cement Pastes and Test Method for Determination of Normal Consistency;
B2 Test Method for Time of Set of Hydraulic Cement Paste - Vicat Needles;
B3 Test Method for Time of Set of Hydraulic Cement Paste - Gillmore Needles;
B4 Test Method for Determination of Atmospheric Steam Expansion;
B5 Test Method for Determination of Autoclave Expansion;
B6 Test Method for Determination of Early Stiffening of Cement Paste;
B7 Test Method for Determination of Heat of Hydration;
C1 Standard Practice for Mechanical Mixing of Hydraulic Cement Mortars and Test Method for Determination of Flow;
C2 Test Method for Determination of Compressive Strengths;
C3 Test Method for Determination of Water Retention of Masonry Mortar;

C6 Test Method for Determination of Sulphate Resistance;
C7 Test Method for Determination of 28-Day Activity Index (Granulated Blast-Furnace Slag-Portland Cement); and
C8 Test Method for Determination of Sulphate Resistance of Mortar Bars Exposed to Sulphate Solution.
This Standard describes the materials and equipment used in testing hyraulic cements, supplementary cementing materials, and cementitious hydraulic slag.
