DEWALT Pure110 Epoxy Adhesive Anchoring System

INTRODUCTION

Pure110+® Epoxy Adhesive Anchoring System and Installations with Core Drilled Holes into Concrete
DEWALT has conducted supplemental testing on the Pure110+ for use with threaded rods and rebars into diamond core drilled holes. Up until now, the Pure110+ has had published performance data in holes drilled with a hammer- drill into concrete (i.e. rotary impact drills or rock drills with a carbide drill bit). This information is provided in our published information and included in ICC-ES ESR-3298. DEWALT has performed additional testing with Pure110+ in holes drilled into concrete with a diamond core bit to also offer bond strength performance data for this drilling method. The information presented below is based on test results and assessment of data in accordance with ICC-ES AC308 and ACI 355.4. The tabulated information is provided with the intention it will be considered for use to determine adhesive anchor design strengths in concrete in accordance with ACI 318 Chapter 17 and CSA A23.3 Annex D. See the Pure110+ technical pages and ESR-3298 at www.DEWALT.com for additional design information, including steel strength and concrete breakout strength design information which may be needed to complete a full anchor design.

Permissible installation conditions6

For SI: 1 inch = 25.4 mm, 1 psi = 0.006894 MPa. For pound-inch units: 1 mm = 0.03937 inch, 1 MPa = 145.0 psi.

Bond strength values correspond to a normal-weight concrete compressive strength f’c = 2,500 psi (17.2 MPa). For concrete compressive strength, f’c between 2,500 psi and 8,000 psi (17.2 MPa and 55.2 MPa), the tabulated characteristic bond strength may be increased by a factor of (f’c / 2,500)0.10 [For SI: (f’c / 17.2)0.10].
The modification factor for bond strength of adhesive anchors in lightweight concrete shall be taken as given in ACI 318-14 17.2.6 or ACI 318-11 D.3.6, as applicable, where applicable.
The maximum short-term service temperature may be increased to 162°F (72°C) provided characteristic bond strengths are reduced by 3 percent. Long-term and short-term temperatures meet the requirements of Section 8.5 of ACI 355.4 and Table 8.1, Temperature Category B.
Short-term base material service temperatures are those that occur over brief intervals, e.g. as a result of diurnal cycling. Long-term base material service temperatures are roughly constant over significant periods of time.
Characteristic bond strengths are for sustained loads including dead and live loads. Characteristic bond strengths are also applicable for short-term loading.
Permissible installation conditions include dry concrete and water-saturated concrete.
Bond strength values for uncracked concrete are applicable for structures assigned to Seismic Design Categories A and B only.
For structures assigned to Seismic Design Categories C, D, E or F, the tabulated bond strength values for cracked concrete do not require an additional reduction factor applied for seismic tension (αN,seis = 1.0), where seismic design is applicable.

INSTALLATION SPECIFICATIONS

INSTALLATION SPECIFICATIONS FOR PURE110+ ADHESIVE ANCHORS IN CORE DRILLED HOLES
The diamond core drill bit nominal size is the same as the existing carbide drill bit nominal size for each respective threaded rod and reinforcing bar diameter. See the Pure110+ technical pages at www.DEWALT.com for any additional installation information.

DEWALT-Pure110-Epoxy-Adhesive-Anchoring-System-fig-1

For pound-inch units: 1 mm = 0.03937 inch, 1 N-m = 0.7375 ft-Ibf. For SI: 1 inch = 25.4 mm, 1 ft-lIbf = 1.356 N-m.

Torque may not be applied to the anchors until the full cure time of the adhesive has been achieved.
These torque values apply to ASTM A36 / F1554 Grade 36 carbon steel threaded rods and ASTM A193 Grade B8/B8M (Class 1) stainless steel threaded rods.
For any case, it must be possible for the steel anchor element to be inserted into the cleaned drill hole without resistance.
For installations below the minimum edge distance, min, down to the reduced minimum edge distance, min,red, the reduced maximum torque is max,red.
