Safety Notes and Product ApplicationDayton Superior strives to ensure that all products supplied from its manufacturing plants meet or exceed the safety requirementsinherent in the proper use of its products. However, the performance of a product can be greatly affected by the manner in whichthe product is used. It is imperative that the user be instructed in the proper installation and use of the products displayed in thishandbook prior to job application.Product production runs are constantly sampled and tested to assure the user a high standard of quality. Samples are testedin Dayton Superior test facilities or at independent testing laboratories. The safe working loads listed in this handbook weredetermined from the results of the testing program and other industry sources.Dayton Superior publishes the safe working loads and the associated minimum safety factors of its products and stronglyadvises that the minimum safety factors not be compromised. When there are unusual job conditions, the minimum safetyfactors must be increased by the user. Refer to the provisions of the American National Standards Institute (ANSI A 10.9),the Occupational Safety and Health Administration (OSHA) Act, Part 1910, and the American Concrete Institute (ACI)Recommended Practice for Concrete Formwork (ACI 347) and ACI 318 Building Code when considering product safety factors.DAYTON SUPERIOR TECHNICAL ASSISTANCEDayton Superior Technical Assistance has trained personnel to service inquiries, take-offs and details for the users of DaytonSuperior quality splicing accessories.Technical Assistance:877-266-773207/181General andTechnical InfoGeneral and Technical Information
General andTechnical InfoGeneral and Technical InformationTable 1.1 Reinforcing Bar DataReinforcing BarsSize Designations and Nominal DimensionsBar SizeDesignationNominal [20]0.750#7[22]–0.875#8[25][25]1.000Ultimate Specified Tensile Capacity (lb)ASTM A615ASTM A706Grade60Grade75Grade80Grade100Grade 60Grade 0Note: The nominal dimensions of a deformed bar are equivalent to those of plain, round bar having the same weight (mass) per foot (meter) as the deformed bar. Nearly all reinforcing bars currently producedin the USA are marked with the metric numbers 13, 16, etc., to designate bar sizes. These bar numbers correspond to the traditional designations, 4, 5, etc., as shown in the table above. ACI 318-14 still lists thebar sizes traditionally using #3 - #18 designations. The tables in this manual typically designate bar sizes as #3[#10] or just with the traditional designation, #3.Table 1.2 Mechanical Requirements for Standard ASTM Deformed Reinforcing BarsNote: For the mechanical requirements of rail-steel and axle-steel bars, see ASTM specifications A616 and A617, respectively.Type of Steeland ASTMDesignationASTM A615Carbon SteelASTM Strength2(psi)3-64040,00060,000#3 – 11%#4-6 – 12%#3-5 – 3½ d#6 – 5d6060,00090,000#3-6 – 9%#7-8 – 8%#9-11, 14, 18 – 7%#3-5 – 3½ d#6-8 – 5d#9-11 – 7d#14, 18 (90 ) – 9d7575,000100,000#3-8 – 7%#9-11, 14, 18 – 6%#3-8 – 5d#9-11 – 7d#14, 18 (90 ) – 9d8080,000105,000#3-8 – 7%#9-11, 14, 18 – 6%#3-8 – 5d#9-11 – 7d#14, 18 (90 ) – 9d100100,000115,000#3-8 – 7%#9-11, 14, 18 – 6%#3-8 – 5d#9-11 – 7d#14, 18 (90 ) – 9d6060,00078,00080,0004#3-6 – 14%#7-11 – 12%#14, 18 – 10%#3-5 – 3d#6-8 – 4d#9-11 – 6d#14, 18 – 8d8080,00098,000100,0004#3-11 – 12%#14, 18 – 10%#3-5 – 3½ d#6-8 – 5d#9-11 – 7d#14, 18 – 9d3-111418Maxim
ACI 318 Chapters 18 and 25 state the requirements for mechanical splices. They are: Type 1 Mechanical Splice shall develop in tension and compression as required at least 125% of the specified yield of the bar. Example: For ASTM A615 Grade 60 bar: 1.25 x 60,000psi 75,000psi
the basket and can be secured with large nails which can be either hand driven or shot from a powder actuated gun. (See Figure 2B) Once the concrete is placed and is set, sawing can take place across the center line of the basket usually at a depth of ¼ of the slab thickness thus allowing the slab to crack and form the nec-essary contraction .

Important Notes - Concrete Page 1 IMPORTANT NOTES Concrete INTRODUCTION Concrete is the world's most widely used construction product that consists of mainly Portland cement mixed with sand, water and gravel. Concrete has high compressive strength but limited tensile strength, and rebar corrosion can cause concrete to spall.
