Early Age Concrete and its Effect on Adhesive Anchor Bond Strength in
Concrete
ACI 318-19, Chapter 17 and ACI 318-14, Chapter 17 (and by reference to the
2021 IBC, and the 2018 IBC and 2015 IBC, respectively) require that adhesive
anchors be installed in concrete with a minimum age of 21 days at the time of
installation. DEWALT currently publishes bond strengths that are based on
concrete which has achieved its 28-day compressive strength and has cured for
a minimum of 21 days. Concrete that is less than 21 days old is considered
early age (aka ‘green’) and may influence the performance of adhesive anchors.
Occasionally, waiting a minimum of 21 days to install adhesive anchors is not
feasible, often due to scheduling and job site logistics. As a result, DEWALT
has conducted progressive laboratory testing with several adhesive anchor
systems at various concrete ages and adhesive cure time intervals. The table
below shows the concrete age at the time of anchor installation crossed with
the adhesive cure time after anchor installation. If installations in early-
age concrete are considered, the corresponding reduction factor derived from
testing for the given conditions is provided and must be applied to the bond
strength when calculating the design bond strength capacity for the given
anchor, as applicable.

- Installing adhesive anchors in concrete having a minimum age of less than 21 days at the time of anchor installation is not in compliance with ACI 318 and must be approved by the engineer of record and AHJ, as applicable. Actual concrete compressive strength at the time of anchor installation must be used for design.
- Results shown are based on tension tests conducted in accordance with ACI 355.4/ASTM E488 in dry uncracked normal weight concrete at room temperature. The average minimum 7-day concrete compressive strength was approximately 2300 psi.
- Holes were drilled with a hammer drill and standard carbide drill bit and cleaned following published instructions. Hollow drill bits (DEWALT DustX+ System) may be considered, as applicable.
- Published minimum cure times vary based on the adhesive anchor system and the temperature of the base material. Anchors were not loaded until time of testing.
- See published literature for the specific adhesive anchor system for minimum cure times and additional design information which is available at www.DEWALT.com.
- The reduction factor for early age concrete is supplemental to all other relevant design considerations for the specific application, as applicable.
In addition to what is presented previously in this bulletin, DEWALT has also conducted supplemental installations and testing in 3-day old concrete with the following adhesive anchor system.

- Installing adhesive anchors in concrete having a minimum age of less than 21 days at the time of anchor installation is not in compliance with ACI 318 and must be approved by the engineer of record and AHJ, as applicable. Actual concrete compressive strength at the time of anchor installation must be used for design.
- Results shown are based on tension tests conducted in accordance with ACI 355.4/ASTM E488 in dry uncracked normal weight concrete at room temperature. The minimum 3-day concrete compressive strength was approximately 1650 psi.
- Holes were drilled with a hammer drill and standard carbide drill bit and cleaned following published instructions. Hollow drill bits (DEWALT DustX+ System) may be considered, as applicable.
- Published minimum cure times vary based on the adhesive anchor system and the temperature of the base material. Anchors were not loaded until time of testing.

- The reduction factor for early age concrete is supplemental to all other relevant design considerations for the specific application, as applicable.
The adhesive anchor systems will achieve published design strengths for relevant loading conditions when the product is properly installed into holes drilled in concrete. The adhesive anchors must be installed in accordance with all other published installation instructions specific to the application and conditions of the connection.
Product Usage Instructions
Before installing adhesive anchors, ensure the following:
- The concrete has a minimum age of 21 days at the time of anchor installation.
- Obtain approval from the engineer of record and AHJ (Authority Having Jurisdiction) if installing in concrete with an age of less than 21 days.
- Use the actual concrete compressive strength at the time of anchor installation for design purposes.
Test Conditions
The bond strength reduction factor and cure times mentioned in the manual
are based on the following test conditions:
- Tension tests were conducted in dry uncracked normal-weight concrete at room temperature.
- Average minimum 7-day concrete compressive strength of approximately 2300 psi.
- Holes drilled with a hammer drill and standard carbide drill bit, following published instructions.
Cleaning Options
For cleaning the drilled holes, consider the following options:
- Follow the published instructions for cleaning using a standard method.
- Consider using hollow drill bits (DEWALT DustX+ System) if applicable.
Minimum Cure Times
The minimum cure times vary based on the adhesive anchor system and the
temperature of the base material.
- Anchors should not be loaded until the specified minimum cure time has passed.
- Refer to the published literature for the specific adhesive anchor system for minimum cure times and additional design information available at www.DEWALT.com.
Reduction Factor for Early Age Concrete
The reduction factor for early age concrete is supplemental to all other
relevant design considerations for the specific application.
Frequently Asked Questions (FAQ)
Q: Can I install adhesive anchors in concrete less than 21 days old?
A: No, installing adhesive anchors in concrete with a minimum age of less than
21 days is not compliant with ACI 318. Approval from the engineer of record
and AHJ must be obtained, and the actual concrete compressive strength at the
time of installation must be used for design.
Q: What are the test conditions for bond strength reduction factor and cure
times?
A: The bond strength reduction factor and cure times mentioned in the manual
are based on tension tests conducted in dry untracked normal-weight concrete
at room temperature. The average minimum 7-day concrete compressive strength
was approximately 2300 psi.
Q: How should I clean the drilled holes?
A: Follow the published instructions for cleaning using a standard method.
Alternatively, consider using hollow drill bits (DEWALT DustX+ System) if
applicable.
Q: When can I load the anchors?
A: Anchors should not be loaded until the specified minimum cure time has
passed. Refer to the published literature for the specific adhesive anchor
system for accurate minimum cure times.
