1 General Information General Information Pure15 0-PRO Epoxy Injection Adhesive Anchoring System ProDUCT DESCRIPTION The Pure150-PRO is a two-component epoxy adhesive anchoring system. The system includes injection adhesive in plastic cartridges, mixing nozzles, dispensing tools and hole cleaning equipment. The Pure150-PRO is a high strength adhesive designed for various applications and hole drilling techniques. It is also very suitable for bonding rebar to concrete as post-installed reinforcement application. SECTION CONTENTS General Information Installation Information Design Information Material Information Ordering Information System Components GENERAL APPLICATIONS AND USES FEATURES AND BENEFITS Designed for use with reinforcement bars of internationally common grades Consistent performance in uncracked and cracked concrete Flexible anchorage lengths of up to 2000 mm Simple installation Versatile low odor formula with long working time Applicable for wide range of medium temperatures Cartridge design allows multiple uses using extra mixing nozzles ApprovalS AND LISTINGS EOTA TR 023 F240 REBAR CONNECTIONS Loading Conditions A+ A B C Pure150-PRO Epoxy Reinforcement Bar Grades f y = 400 to 600 MPa APPROVALS eta-13/0049 STATIC QUASI-STATIC Suitable Base Materials TECH MANUAL 2013 DeWalt Volume 2 9/

Blow the hole clean using a hand pump or compressed air 2 times minimum. 3.) Brush the hole with the proper wire brush 2 times minimum. For complete installation instructions, see technical approval. 4.) Blow the hole clean using a hand pump or compressed air 2 times minimum. 5.) Fill the hole up to approximately 2/3 with adhesive. 6.) Push the rebar into the hole while turning slightly. 7.) Allow the adhesive to cure for the time specified for the actual concrete temperature prior to applying any load

3 Design Information Design Information The following information is meant to give the designer aid in the preliminary design process. No responsibility is taken for the correctness of the data. Reinforcement bars installed by Pure150-PRO adhesive proved as good as cast-in reinforcement bars. For this reason their design complies with the concrete design approach which basically determines the anchorage length required to transfer a given design load from the reinforcement bar into the concrete. For further details and background information please see the introduction of this manual and to the respective design codes. anchorage length Basic anchorage length: (EN Section 8.4.3) l b,rqd = (ø / 4) x (s sd / f bd ) with: ø = diameter of the rebar s sd = calculated design stress of the rebar f bd = design value of bond strength Basic design value of bond strength f bd for various concrete strength classes [MPa] (valid for good bond conditons) C12/15 C16/20 C20/25 C25/30 C30/37 C35/45 C49/59 C45/55 C50/ Reduction factor for poor bond condition as defined in EN Section 8.4.2: h = 0.7 Design anchorage length Anchorage (EN Section 8.4.4) Design anchorage length Overlap joint (EN Section 8.7.3) l b,d = l v l 0 l v l b,d = l v l b,d = l v l b,d = a 1 a 4 a 5 l b,rqd l b,min l b,d = l o l o = a 1 a 5 a 6 l b,rqd l 0,min a 1 = 1.0 (straight bars) a 1 = 1.0 (straight bars) = (c d ) / c d = min{s/2; c} = (c d ) / c d = min{s/2; c} = 1.0 (no transverse reinforcement) = 1.0 (no transverse reinforcement) a 4 = 1.0 (no welding) a 5 = p p = ultimate transverse pressure l b,min = max {0.3 l b,rqd ; 10 ; 100 mm} under tension = max {0.6 l b,rqd ; 10 ; 100 mm} under compression a 4 = p p = ultimate transverse pressure a 5 = (p t / 25) = lapped bar ratio p t l 0,min = max {0.3 a 6 lb,rqd ; 15 ; 200 mm} under tension TECH MANUAL 2013 DeWalt Volume 2 9/
