GENERAL INFORMATION

AVAILABLE IN NEW ZEALAND ONLY
(Australia refer to ChemSet TM Reo502 TM PLUS range)

Product

EPCON ™ C6 PLUS is a heavy duty pure Epoxy for anchoring threaded studs and reinforcing bar into cracked and uncracked concrete.
Compliance
European Technical Assessment (option 1) – ETA-18/0675 Design according to:

•  AS1170.4 – Earthquake Actions
• EN1992-4 (formerly ETAG001 Annex C, E & TR045)
• NZS3101 (A3) Section 17 – Seismic Design C1
• Use enclosed data for simplified calculation method
  Use Ramset TM iExpert Anchor Software for optimised calculation or where a greater range of anchor layout detail is needed.

Benefits, Advantages and Features

• 100 year working life Greater productivity:
•  Anchors in dry, damp, wet or flooded holes
• Easy dispensing even in cold weather Greater security:
• Strong bond
• Rated for sustained loading Versatile:
• Anchors in carbide drilled and diamond drilled holes*
• Cold and temperate climates Greater safety:
• Low odour
• VOC Compliant
• Suitable for contact with drinking water

Installation

1. Drill recommended diameter and depth hole.
2. Important: Use Ramset ™ Dustless Drilling System to ensure holes are clean. Alternativly clean dust and debris from hole with stiff wire or nylon brush and blower in the following sequence: blow x 2, brush x 2, blow x 2, brush x 2, blow x 2.
3. Dispense adhesive to waste until colour is uniform light grey ( 2-3 trigger pulls ). Insert mixing nozzle to bottom of hole. Fill hole to 3/4 the hole depth slowly, ensuring no air pockets form.
4. Insert Ramset ™ ChemSet ™ Anchor Stud/rebar to bottom of hole while turning.
5. Allow EPCON ™ C6 PLUS to cure as per setting times.
6. Attach fixture.

Installation and performance details: EPCON ™ C6 Plus and ChemSet ™ Anchor Studs

* For anchor spacings or edge distances less than the minimum, please refer to the simplified strength limit state design process to verify capacity.
** Tension values are based on service temperature limits -40˚C to +70˚C only. If service temperature limits is beyond this range please contact Ramset Engineer.
**Note: Seismic Cracked concrete combined pull-out and concrete cone resistance, tension = N 0 Rd,p,seis = αNseis N 0 Rk,p,seis /γMsp where γMsp = 1.5

***Note: Seismic Cracked Concrete steel resistance, tension = NRd,s,seis = αNseis N 0 Rk,s,seis / γMs (kN) where γMs = 1.5 (Grade 5.8 & 8.8 steel), γMs = 1.87 (A4 316 SS) and γMs = 1.5 (HCR 1.4529 stainless steel)
# Note: HOT-DIP GALVANIZED ANCHORS – for Seismic C1reduced characteristic steel shear capacity the following reduction factors shall apply;
M10 Multiply VRd,seis *0.47
M12 Multiply VRd,seis *0.47
M16 Multiply VRd,seis *0.54
M20 Multiply VRd,seis *0.54

ENGINEERING PROPERTIES ChemSet ™ Anchor Studs and Threaded Rod

Refer to “Engineering Properties” for ChemSet ™ Anchor Studs Grade 5.8 and AISI 316 Stainless Steel in the SARB ANZ on page 141.

Select anchor to be evaluated

Table 1a Indicative combined loading – interaction diagram

Notes:

• Shear Limited by Grade 5.8 zinc plated steel capacity
• Tension limited by C1 concrete capacity using nominal depths
•  No edge or spacing effects
•  f’c = 30 MPa
