ASTM C881: Standard Specification for Epoxy Resin Based Bonding Systems for Concrete
Seven types of epoxy system are defined, based on the application:
Type I: For Bonding Hardened Concrete to Hardened Concrete (non-load bearing)
Type II: For Bonding Fresh Concrete to Hardened Concrete (non-load bearing)
Type III: Bonding Skid-Resistant Materials to Hardened Concrete (low modulus)
Type IV: Bonding Hardened Concrete to Hardened Concrete (load bearing)
Type V: Bonding Fresh Concrete to Hardened Concrete (load bearing)
Type VI: Bonding and Sealing Pre-Cast Elements with Internal Tendons and Span by Span Erection
Type VII: Sealing Segmental Pre-Cast Elements
The epoxy is characterized by viscosity into three grades:
Grade 1: Low Viscosity (2,000 cp maximum)
Grade 2: Medium Viscosity (2,000 – 10,000 cp)
Grade 3: Non-Sag
Use temperature is defined by classes:
Class A: For use below 40°F
Class B: For use between 40°F and 60°F
Only defined for Types I through V
Class C: For use above 60°F
Class D: For use between 40°F and 65°F
Only defined for Types VI and VII
Class E: For use between 60°F and 80°F
Class F: For use between 75°F and 90°F
ASTM C 1059: Standard Specification for Latex Agents for Bonding Fresh To Hardened
Concrete
Type I (Redispersable) latex bonding agents are restricted for use in interior work not subject to water
immersion or high humidity
Type II (Non-redispersable) latex bonding agents may be used for areas subject to high humidity or immersion
in water as well as in dry areas
ASTM C 309 Standard Specification for Liquid Membrane-Forming Compounds for Curing
Concrete
The physical appearance of the curing compound is described by three types:
Type 1
The curing compound is clear or translucent without dye
Type 1-D
The curing compound is clear or translucent with fugitive dye
Type 2
The curing compound is white pigmented
The type of “solids” in the curing compound is characterized into one of the following classes:
Class A
No restrictions on the type of solids
Class B
Solids must be a resin (NO wax based solids)
ASTM C 1315 Standard Specification for Liquid Membrane-Forming Compounds Having
Special Properties for Curing and Sealing Concrete
The physical appearance of the curing and sealing compound is described by two types:
Type I
The curing and sealing compound is clear or translucent
Type II
The curing and sealing compound is white pigmented
The tendency for the curing and sealing compound to yellow or discolor upon exposure to UV light is
classified as follows:
Class A curing and sealing compounds are essentially non-yellowing
Class B curing and sealing compounds are for applications where moderate yellowing is not prohibited
Class C curing and sealing compounds are for use where significant color change is acceptable
ASTM C 1107 Standard Specification for Packaged Dry, Hydraulic-Cement Grout (Non-Shrink)
Prior to 2005, ASTM C 1107 specified three grade classifications for non-shrink grout:
Grade A Pre-Hardening Volume-Adjusting
Grade B Post-Hardening Volume-Adjusting
Grade C Combination Volume-Adjusting
In 2005 the grading classifications were removed from ASTM C 1107. However, many project
specifications have not been updated and still refer to these three grades. The current ASTM C 1107
requires that all non-shrink grouts undergo the same testing and comply with the same requirements.
Therefore, there are no grades in the current C 1107 specification.
ASTM C 920 Standard Specification for Elastomeric Joint Sealants
Sealant types are characterized by number of components:
Type S
Single component, typically air or moisture cured
Type M
Two or more components, chemically cured
Grades are classified by viscosity:
Grade P
Pourable sealant, also referred to as self-leveling
Grade NS
Non-sag sealants
Sealant classes are defined by their ability to withstand movement:
Class 12-½
Capable of handling movement (contraction or expansion) of 12.5% of the original joint width
Class 25
Capable of handling movement (contraction or expansion) of 25% of the original joint width
Class 35
Capable of handling movement (contraction or expansion) of 35% of the original joint width
Class 50
Capable of handling movement (contraction or expansion) of 50% of the original joint width
Class 100/50 Capable of handling movement of 50% contraction and 100% expansion
ASTM C 928 Standard Specification for Packaged, Dry, Rapid-Hardening Cementitious
Materials for Concrete Repairs
Three types (R1, R2, and R3) of packaged, dry, rapid-hardening cementitious materials are classified
by physical and performance properties:
