AC200+ Adhesive Anchoring System
AC200+™ Adhesive Anchoring System and Installations with DEWALT DustX+™
Automatic Dust Extraction
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) requires that adhesive
anchors for concrete be installed using a specific drilling method. This is
because the drilling method used to create a hole in concrete and the
subsequent manufacturer recommended hole cleaning procedure for the adhesive
system has a significant effect on the bond strength of the installed adhesive
anchors.
Up until now, DEWALT published bond strengths for AC200+ adhesive anchors that
are based on drilling into concrete using a hammerdrill with a carbide drill
bit followed by a traditional hole cleaning process (e.g. blowing the hole
clean, brushing the hole, blowing the hole clean again). Fortunately,
additional hole drilling and cleaning options are now available for end users
from DEWALT due to the increased attention being given to dust control
solutions on jobsites in construction.
The DustX+ system allows users to drill
holes in concrete and clean the holes during the drilling process at the same
time (no extra cleaning steps are necessary with this system). The hollow
drill bits are attached to a self-cleaning HEPA vacuum which provide the dust
collection during drilling. DEWALT has conducted extensive supplemental
laboratory testing on AC200+ adhesive anchors installed in holes drilled and
cleaned using the DustX+ system in dry concrete.
The table below shows the results of the testing adhesive anchor system
crossed with the installation and cleaning method along with the corresponding
reduction factor derived from testing that should be applied to the bond
strength when calculating the bond strength capacity for the given adhesive
anchor and relevant conditions.
Adhesive Anchor System| Drilling Method| Cleaning Method| Bond Strength
Reduction Factor, andb
---|---|---|---
DEWALT AC200+| Hammer-drilling with standard carbide drill bits| Blow 2x,
Brush 2x, Blow 2x| N/A (baseline values)
Hammer-drilling with hollow drill bits (DustX+)| Hollow drill bits (DustX+)|
1.0 (no reduction)
N/A = Not applicable.
- Results shown are based on tension tests conducted in accordance with ACI 355.4/ASTM E488 in dry cracked and uncracked normal weight concrete; holes were drilled with a hammer drill and and standard carbide drill bit or hollow drill bit, as applicable.
- Standard carbide drill bits and hollow drill bits must meet the requirements of ANSI B212.15; ANSI compliance for hole drilling is required by ICC-ES ESR-4027.
- See published literature for the specific adhesive anchor system for additional design and installation information which is available at anchors.DEWALT.com.
AC200+ adhesive anchors will achieve published design strengths when the product is installed properly into holes drilled and cleaned in dry concrete with the DustX+ system.
