192 Chem-Stud SPIN TYPE CAPSULE ADHESIVE BASE MATERIAL Solid Concrete SIZE RANGE 3" to 1-1" Anchor Rod, No. 3 to No.10 Reinforcing Bar ANCHOR MATERIAL Ester Based Resin PRODUCT DESCRIPTION The Chem-Stud Anchor System consists of self contained two-part glass capsules and matching chisel pointed anchor rods which are installed using a rotary hammer drill and rod adapters. The Chem-Stud adhesive is an ester based resin material packaged in a single use glass capsules designed for installation of 3" through 1-1" threaded rods in solid concrete and masonry materials. It can also be used for reinforcing bars. CHEM-STUD CAPSULE CHEM-STUD 5" (16mm) The outer capsule contains epoxy acrylate resin (vinyl ester) in which quartz aggregate is suspended. The inner capsule contains a benzoyl peroxide hardening agent. When the components are combined, they form an adhesive mortar which mechanically bonds the anchor rod to solid base material. This type of system must be used with a chisel pointed anchor rod and must be spun into the anchor hole using a rotary hammer drill. CHEM-STUD CHISEL POINTED HARDWARE Capsule Chisel-Pointed Rod Internally Threaded Insert The threaded anchor rods have a 45 chisel point cut on one end to properly mix the components contained in the capsule during installation. A 90 point is formed on the internally threaded inserts. The threaded rod or reinforcing bar used must have a chisel point to mix the components contained in the capsule during installation.

CHEM-STUD RECOMMENDED SETTING TIME The setting times the for the Chem-Stud adhesive mortar are listed below. The setting time is the minimum time required for the mortar to reach its published physical properties and is listed for the base material temperature, not ambient air temperature. For example, when making installations inside a building in exterior walls during the winter, the temperature of the hole may be different than the interior temperature and should be measured to determine the setting time required. In order to ensure proper mixing, the capsule contents should be conditioned to 60 F. prior to use. BASE MATERIAL TEMPERATURE SETTING TIME 68 F. & over 20 minutes 50 F. to 68 F. 30 minutes 32 F. to 50 F. 1 hour 23 F. to 32 F. 5 hours 14 F. to 23 F. 10 hours 5 F. to 14 F. 18 hours 0 F. to 5 F. 24 hours Cure Time should be doubled for wet concrete. CHEM-STUD ADHESIVE PROPERTIES RESISTANCE OF CHEM-STUD ADHESIVE TO S The resistance of the cured Chem-Stud adhesive to various chemicals was determined according to ASTM Specification C 581 by laying molded samples of the resin in the respective chemical agents. The samples were subjected to a bending strength test before and after a 12 month exposure to the chemicals. The adhesive was rated as resistant if there was no visible deterioration and less than 25% reduction in bending strength. This exposure is extreme. Under normal installation conditions, the adhesive is exposed to the chemical agents only at the surface of the concrete around the top of the anchor hole.

196 PERFORMANCE DATA ULTIMATE LOAD CAPACITIES - THREADED ROD IN CONCRETE The following capacities are the ultimate or failure load for the Chem-Stud adhesive when tested with high strength anchor rod in several compressive strengths of concrete. The capacity of the anchor rod should be taken into account in the design of any anchorage. The combinations of capsules shown are required to ensure that the proper bond area is achieved for each of the embedments listed. Do not attempt to use more than two capsules as the drill equipment used for installation may not have enough torque to properly spin the rod into the capsule. For installations where the combined length of capsules exceeds the length of the anchor hole, crush the first capsule using the anchor rod, then insert the second capsule. The larger capsule should be inserted into the anchor hole first. ANCHOR DRILL EMBED. MAX.

The steel strength values are based on ASTM Standard A 615. The ultimate tension loads for the Chem-Stud adhesive should be used as a guide. Actual results may vary depending on the base material condition and reinforcing bar tolerances. A chisel point must be cut at the end of the reinforcing bar that is initially installed through the capsule(s). The combinations of capsules shown are required to ensure that the proper bond area is achieved for each of the embedments listed. Do not attempt to use more than two capsules as the drill equipment used for installation may not have enough torque to properly spin the rod into the capsule. For installations where the combined length of capsules exceeds the length of the anchor hole, crush the first capsule using the anchor rod, then insert the second capsule. The larger capsule should be inserted into the anchor hole first. REBAR DRILL EMBED. NUMBER AND SIZE ULTIMATE BOND STRENGTH (LBS.) GRADE 60 REBAR SIZE DIA.

200 DESIGN CRITERIA BASE MATERIAL THICKNESS The minimum recommended thickness of solid concrete or masonry base material, BMT, when using an adhesive anchor is 125% of the embedment to be used. For example, when installing an anchor to a depth of 4", the base material should be at least 5" thick. Conversely, the maximum embedment should be 80% of the base material thickness. If a concrete slab is 10" thick, an 8" depth would be the maximum recommended anchor embedment. This does not apply to products designed for installation in hollow base materials. S S E D = Anchor Size S = Spacing E = Edge Distance BMT = Base Material Thickness COMBINED LOADING For anchors loaded in both shear and tension, the combination of loads should be proportioned as follows based on the Uniform Building Code: T 5 /3 () S VS T A () V A Where: Ts = Applied Service Tension Load TA = Allowable Tension Load Vs = Applied Service Shear Load VA = Allowable Shear Load Dependent upon the election to conduct certain optional independent test procedures, many ICBO evaluated products are currently analyzed more conservatively with the following proportion. T () S VS T A () V A TS TA 1.0 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 0 5 /3 + 1 + 1 TS VS () () TA VA + 1 (straight line) 0.1 0.2 03 0.4 0.5 0.6 0.7 0.8 0.9 1.0 VS VA E 5 /3 TS VS () () TA VA D 5 /3 S + 1 (parabolic) BMT S ADHESIVE ANCHOR SPACING AND EDGE DISTANCE Adhesive type anchors can be installed closer to the edge of a concrete slab than mechanical anchors with no cracking of the base material. The published ultimate and allowable working loads are based on testing conducted at the spacing and edge distance required to obtain maximum load and should be reduced to account for decreased spacing and edge distance. The reduction load factors listed are cumulative. For example, the allowable working load for an anchor which is installed at a spacing and an edge distance less than that required for maximum load capacity would be multiplied by the appropriate factor from both the spacing and edge distance tables. The factors are normally applied to the allowable working load of the adhesive resin and then compared to the allowable strengths of the steel anchor rods used. See the Design Example featured earlier in this manual. SPACING BETWEEN ADHESIVE ANCHORS The following table lists the load reduction factor, Rs, for each anchor diameter, D, based on the center to center anchor spacing. To obtain the maximum working load in tension or shear, a spacing of 8 anchor diameters (8D) or greater should be used. The minimum recommended anchor spacing is 4 anchor diameters (4D) at which point the allowable working load for the adhesive resin should be reduced by 30%. Anchor spacing closer or less than 4 diameters (4D) need to be field tested. Actual base material conditions will determine any applicable reduction factor.

201 EDGE DISTANCE FOR ADHESIVE ANCHORS EDGE DISTANCE - TENSION For adhesive anchors loaded in tension, the following table lists the load reduction factor, Re, for each anchor diameter, D, based on the anchor center to edge distance. To obtain the maximum tension load, an edge distance of 6 anchor diameters (6D) and greater should be used. The minimum recommended edge distance is 4 anchor diameters (4D) at which point the allowable working load for the adhesive resin should be reduced by 40%. Edge distances closer or less than 4 diameters (4D) need to be field tested. Actual base material conditions will determine any applicable reduction factor.

The anchor holes should be prepared following the standard installation procedures with the following exceptions. Special care should be taken to clean the anchor hole as a slurry of concrete paste tends to form on the walls of the anchor hole when drilling under water. Insert the proper size capsule into the anchor hole. Be sure the capsule is fully inserted to the bottom of the hole. Follow the standard installation instructions for spinning the anchor rod used into the capsule with an appropriate tool for submerged use. The setting time of the Chem-Stud adhesive in submerged applications depends upon the base material temperature as shown previously. Laboratory tests and field experience have shown that a decrease of 15 to 20% in the ultimate tension load capacity can be expected for an adhesive anchor which is installed under water. The design professional should include this reduction in his calculations. If the tension capacities are critical, a job site test is recommended. 1" www.powers.com
