29. Outline What is the P2P Initiative? What is a Prescriptive Specification? What is a Performance Specification? What are the Benefits of P2P? What Activities are Underway? How to Specify Concrete using Current Codes?

30. What is the P2P Initiative? Stands for Prescription-to-Performance Initiative of the ready mixed industry through the NRMCA Coordinated by P2P Steering Committee under the NRMCA Research, Engineering and Standards Committee Members include technical representatives, product suppliers, contractors, engineers, and architects

31. Why Performance? Shifting Expertise to Concrete Producers Reduce Conflicts in Specifications Identify Roles and Responsibilities Controlling Construction Cost (through optimization) Meet Greater Demands on the Product (through innovation) Improving Quality Systems Training and Certification Programs

32. Construction Cost Savings of P2P Innovative construction means and methods Improved construction schedules More efficient structural designs Simplified specifications and submittal process Optimized mix designs

33. Innovative Technologies High-Strength Concrete High-Performance Concrete Self- Consolidating Concrete

34. Improved Quality Systems Product Development Testing Labs Material Handling

35. NRMCA Training and Certifications Plant and Truck Certification Plant Manager Certification Concrete Technologist Certifications Certified Delivery Professional (drivers) Concrete Certified Sales Professional Under development Concrete technologist responsible for performance mixes Concrete producer certification based on quality system

36. P2P Goals Allow performance specifications as an alternative to current prescriptive specifications Leverage expertise of all parties to improve quality and reliability of concrete construction Assist architects/engineers to address concrete specifications in terms of functional requirements Allow flexibility on the details of concrete mixtures and construction means and methods Better establish roles and responsibilities based on expertise Continue to elevate the performance level of the ready mixed concrete industry Foster innovation and advance new technology at a faster pace

37. What is a Prescriptive Specification? Details mixture proportions and construction means and methods Do not always cover intended performance May conflict with intended performance Example: Low w/c for durability could increase thermal and shrinkage cracking Requirements are generally not directly enforceable Producer held responsible for performance and defects, even though he lacks the freedom to make changes Prevents mixture optimization for performance No incentive for quality control / batch uniformity

38. Prescriptive Specification Intended Performance Placing/Finishing Strength Min Shrinkage Resistance To: Freeze-Thaw Corrosion Sulfate attack ASR Cracking Abrasion Prescriptive Criteria Slump Max w/cm ratio Min cement content Min/max air Min/Max pozzolans/slag Blended cements Aggregate grading Source Limitations Chloride Limits

39. Prescriptive Specification Intended Performance Placing/Finishing Strength Min Shrinkage Resistance To: Freeze-Thaw Corrosion Sulfate attack ASR Cracking Abrasion Prescriptive Criteria Slump Max w/cm ratio Min cement content Min/max air Min/Max pozzolans/slag Blended cements Aggregate grading Source Limitations Chloride Limits Some prescriptive criteria are required by code but many are not

40. Prescriptive Specification Example w/c ratio = 0.40 Min. cement = 600 pcy Strength = 3500 psi No SCM Aggregate grading 8 – 18% No reactive aggregate Low alkali cement Shrinkage = 0.04% max No cracking No curling Slump 5 ± 1 inch Setting time 4 ± 0.5 hrs Max temp 85° F Impermeable Uniform color

41. Example: Water Cement Ratio Cement Water Air Cement Water Air Paste

42. w/cm alone does not control strength Source: ACI 211

43. w/cm alone does not control permeability Source: ACI 232, 233, 234

44. What is a Performance Specification? Performance requirements of concrete Hardened state for Service (meeting owner’s requirements) Plastic state for Constructability (meeting the contractor’s requirements) Focus on performance and function Assignment of responsibility Flexibility to adjust mixture ingredients and proportions to achieve consistent performance Changes in weather conditions Changes in materials Measurable and enforceable Defined test methods and acceptance criteria

45. How would it work? Qualification requirements would be established for producers Performance criteria would be specified by the A/E Contractor would partner with producer to establish constructability criteria Submittal will demonstrate compliance with specified requirements Compliance through pre-qualification tests and limited jobsite acceptance tests

46. Who Benefits from P2P? Owners Engineers/Architects Concrete Contractors Concrete Producers

47. Benefits to Owners from P2P Improved quality Improved performance Reduced construction time Reduced cost Higher confidence in concrete construction Innovative solutions

48. Benefits to Engineers/Architects Focus on function rather than composition Strength, Durability, Shrinkage, etc. Simplified submittal review Improved product consistency Reduced conflict with contractor/producer Reduced risk Producer responsible for concrete mix design Innovative solutions

49. Benefits to the Contractors Improved communication / coordination Constructability requirements addressed Predictable performance Innovate on construction means and methods

50. Benefits to Concrete Producers Eliminates conflicts in specifications Improved clarity in what needs to be furnished Encourages innovation Rewards investment in quality control Allows optimization of mixtures for performance Allows adjustment of materials/proportions to compensate for changes in materials and weather Provide innovative products

51. What are the Challenges? Acceptance of Change Trust / Credibility Knowledge Level (training) Reference Codes and Specifications Prescriptive limitations Measurement and Testing Reliability of existing tests Reliability of jobsite tests

52. What Activities are Underway? Communication Engineers, Architects, Contractors, and Producers Articles and presentations Developing Producer Quality System / Qualifications Developing Model Spec / Code Revisions Look at model codes from other countries (Canada, Europe, Australia) Look at similar initiatives in the US (FHWA and DOTs) Documenting Case Studies Conducting Research Test Methods for Performance Quantifying differences between prescriptive and performance mixes Delivering Training Programs

53. How to Specify Concrete Using Current Codes Objective: Minimize prescriptive requirements Comply with ACI 318 Chapter 3, 4 and 5 Example: 3 story concrete building with first level parking Structural slabs, beams, and columns Slabs-on-grade (parking) Foundation walls Footings Freezing and thawing (with deicing chemicals) Soils contain sulfates (severe) Unusual to have freeze-thaw and sulfate exposure Items in are comments Most concrete does not require prescriptive criteria Yellow

73. Concrete Placement Measure, batch, mix, deliver, and provide delivery ticket for each batch of concrete in accordance with ASTM C 94. Do not add water to concrete during delivery or during placement. Water is permitted to be added to a batch of concrete at the project site before placement of the batch begins provided that the amount of water added does not exceed the allowed amount indicated on the delivery ticket.

74. Field Quality Assurance Testing: Owner shall engage a qualified testing agency to perform concrete field tests and prepare test reports. Concrete Field Tests: Concrete Test Samples: Samples for concrete tests shall be taken in accordance with ASTM C 172.

75. Field Quality Assurance (cont’d) Compressive Strength Tests on concrete: Samples shall be taken not less than once per day, nor less than once for each 150 yd 3 of concrete, nor less than once for each 5000 ft 2 surface area for slabs or walls. Acceptance based on standard cured cylinders in accordance with ASTM C 31 and tested at 28 days in accordance with ASTM C 39. Strength test results are the average of two specimens. Tests of slump, air content, temperature and density shall be made and recorded with the strength test results. Consider testing at 56 or 90 days for high volumes of SCMs. Average of two cylinders represent a strength test result by ACI 318 If a 7 day test is specified for informational purposes (not acceptance), clearly indicate that in the specification. The installer and manufacturer may choose to make additional cylinders for field cured specimens to monitor early age strength for form removal and reshoring. Field cured specimens are typically not recognized for acceptance.

76. Field Quality Assurance (cont’d) Strength of each concrete class shall be deemed satisfactory: The average of three consecutive compressive-strength tests equals or exceeds specified compressive strength Any individual compressive-strength test result does not fall below specified compressive strength by more than 500 psi. When compressive strength tests indicate low strength, follow procedure in ACI 318 chapter 5.6.4 Investigation of low-strength test results

77. Field Quality Assurance (cont’d) Air Content: ASTM C 231. Air content tests shall be performed on concrete at least at the same frequency as compressive strength testing. The provisions of ASTM C 94 shall apply for acceptance of air content of concrete. Only use air content as an acceptance criterion if there is an air content requirement ACI 318 establishes an air content tolerance of ±1.5% ASTM C 94 permits a jobsite adjustment if the air content is low Allows for retesting prior to rejecting concrete

78. Field Quality Assurance (cont’d) Slump: ASTM C 143; one test when concrete is sampled for strength tests. Temperature: ASTM C 1064; one test when concrete is sampled for strength tests. Density: ASTM C 138; one test when concrete is sampled for strength tests. Test results shall be reported to architect, engineer, concrete producer, and concrete contractor within 48 hours of testing.

79. Recap Comply with ACI 318 Place limits on materials in concrete based on the exposure of the concrete. Plan to propose changes to ACI 318 Chapter 4 – Durability Requirements to allow performance-based alternatives Plan to develop model performance-based specifications based on the new provisions
