Pure110+® Adhesive Anchoring System and Installations with DEWALT DustX+™ Automatic Dust Extraction
08321SD Pure110+ Adhesive Anchoring System
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 Pure110+ adhesive anchors
that are based on drilling into concrete using a hammer drill 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 Pure110+ 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, αhdb
---|---|---|---
DEWALT
Pure110+| 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 untracked 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-3298.
- See published literature for the specific adhesive anchor system for additional design and installation information which is available at anchors.DEWALT.com.
Pure110+ 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.
