Technical Circular T-5/95 March 10, 1995

TO: All Headquarters Directors, Prof. Services, Planning & Major Projects All Regional Directors All Regional Managers, Prof. Services, Planning & Operations All District Highways Managers

SUBJECT :

CONCRETE ADDITIVES - SUMMARY OF TYPES AND USES

PURPOSE :

To inform Ministry staff as to the range of concrete admixtures currently used in British Columbia, and to provide general guidelines for appropriate use.

BACKGROUND :

The current edition of MOTH Standard Specifications for Highway Construction Section 211 "Portland Cement Concrete" was written in 1992 for the manufacture of plain concrete. Reference is made therein to Section 314 IIAdmixtures for Portland Cement Concretett. This latter section, written in 1985, discusses only Pozzolan admixtures, referring to CSA standards for details of air-entraining and chemical admixtures.

Many MOTH field staff do not have access to a set of current CSA standards. This Technical Circular is intended to summarize the range of admixtures now in common use in B.C. and will serve as an interim guide until Section 314 of the Standard Specifications is updated.

CONCRETE ADDITIVES - SUMMARY OF TYPES AND USES

1.0 ADMIXTURE TYPES

The main categories of admixture are described in the following section. The names of some commonly-used products are listed at the end. This list is for illustration only, and may not represent the complete range of products on the market.

1.1 Cement Types

Although not truly admixtures, the various types of portland cement, other than Type 10 (Normal) portland cement, are sometimes treated as if they belonged to such a category. Types 20 (Moderate), 30 (High Early Strength), 40 (Low Heat of Hydration), and 50 (Sulphate Resistant) portland cements are seldom encountered in Ministry use.

1.2 Cement Replacements

1.2.1 Pozzolans

Pozzolans, naturally-occurring volcanic ash, are used as an admixture to portland cement. The pozzolan combines with the water-soluble free lime (CaO) from the portland cement, providing additional strength while reducing expansion and permeability of the hardened concrete. Section 314 refers to Type N for natural ash, and Type F for flyash (see below). Sometimes, pozzolans are marketed with combinations of properties, to act as retarders, etc. Current Ministry policy does not permit the use of pozzolans in bridge decks.

1.2.2 Flvash

Flyash is a man-made pozzolan, recovered from coal-burning thermal generating plants. Type F flyash is produced when anthracite, bituminous or sub- bituminous coal is burned; it is generally low in lime, giving lower heat of curing and sulphide and sulphate resistance similar to Type 50 portland cement. Type C flyash comes from lignite or sub-bituminous coal; their higher lime content gives them self-hardening properties, making them more useful for high early strength concrete. In its dry form, flyash is more absorbent and flows more easily than portland cement. Trial mixes must be carried out on each type of flyash to determine the f1yash:cement replacement ratio - usually greater than 1:l.

1.2.3 Silica Fume

Silica fume, also known as condensed silica fume, volatilized silica or microsilica, is a byproduct of electric arc furnaces. It behaves as a pozzolan due to its extreme fineness and high silica content.

CONCRETE ADDITIVES - SUMMARY OF TYPES AND USES

1.3 Accelerators and Antifreeze Admixtures

Because calcium chloride increases heat of hydration, thus increasing the concrete temperature, it was often used to permit placing in unheated forms during the winter. The Ministry does not allow use of chloride admixtures because of corrosion problems.

Recently, other chemical "antifreeze" admixtures have been tried out, including: chlorides, nitrates, sulphates, carbonates, urea and polyglycolester.

1.4 Retarders

Retarding admixtures are used to control setting times and to reduce heat of hydration. They are most often used in hot weather, or in large monolithic pours. They are less often used to permit longer time for finishing of large slabs.

1.5 Air-Entrainment

The entrainment of a small amount of air in concrete, typically 4 to 8%, realize benefits, including: better workability, reduced segregation, reduced permeability and increased freeze/thaw resistance. Improper use of admixtures can cause either excessive air or "entrapped" air (where the air bubbles interconnect), both of which are harmful to concrete.

1.6 Water Reducers

Water reducing admixtures permit reductionof water in concrete mix without loss of slump, or an increase in slump without loss of strength. Some of these admixtures retard setting time of concrete, while others have little or no effect.

1.7 Superplasticisers

Superplasticisers are organic chemical admixtures classified as Category A (melamine based) and Category B (naphthalene based). As with water reducing admixtures mentioned above, superplasticisers may be used either to increase slump without loss of strength, or to retain slump while increasing strength. Superplasticisers are most commonly used where concrete is to be pumped to the forms. A plain concrete mix with a 75 mm slump could have the slump increased to 200 mm or more after addition of superplasticiser. The effect is short-lived, so superplasticiser is usually added to the ready-mix truck at the site. They should be used only where necessary, and the Ministry does not permit their use for bridge decks.

1.8 Water Repellents

Integral water repellant admixtures based on stearic acid are occasionally used on floor slabs, brick mortar and other areas in industrial buildings. They would not normally be encountered in Ministry work.

2.0 DISCUSSION

Admixtures other than pozzolans or air entraining agents are not usually required for the typical small MOTH project. On larger projects, however, superplasticisers are essential where concrete is pumped. Where required by the project conditions, admixtures recognized by CSA can, if used properly, greatly improve the quality of concrete.

3.0 RECOMMENDATIONS

In the early phases of project planning, MOTH staff must obtain complete mix data, including a description of all admixtures, their brand names, dosage, purposes and precautions. No mix should be accepted prior to receiving complete data, regardless of how reputable the testing agency or ready-mix supplier. Most Ministry contracts contain a price item for trial mix preparation. This should be used to verify mix proportions, admixtures and materials on all but the smallest jobs. Questions regarding specific admixtures or their recommended dosage should be referred to the Regional Geotechnical and Materials Engineer, or to the Central Materials Laboratory in Victoria.

LIST OF TYPICAL PRODUCT NAMES

The B . C . Ministry of Transportation and Highways does not have a list of recognized concrete admixtures. Attached, as an interim guide, is a copy of an 8-page list of admixtures accepted by the Ontario Ministry of Transportation. The list was issued in 1992, but is believed to be still current.
