DEWALT Pure 110 Plus Adhesive Anchoring System

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. 1Bond 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]. 2The 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. 3The 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. 4Short-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. 5Characteristic bond strengths are for sustained loads including dead and live loads. Characteristic bond strengths are also applicable for short-term loading. 6 Permissible installation conditions include dry concrete and water-saturated concrete. 7Bond strength values for uncracked concrete are applicable for structures assigned to Seismic Design Categories A and B only. 8 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.
