1 Introduction to SCC and Federal Efforts Gary Jakovich, P.E. FHWA Federal Lands Bridge Office Sterling, VA Louis N. Triandafilou, P.E. FHWA Resource Center Baltimore, MD
2 Topics Covered Funding Program Introduction to SCC What is it? History of Development of SCC Performance Benefits of SCC Characteristics of SCC Mixture Applications of SCC Mix Design Principles Limitations and Areas of Concern Guidelines Research Efforts
3 IBRD Program Promote, Demonstrate, Evaluate and Document: Innovative designs, materials, construction methods, repair, rehabilitation techniques IBRC = $21 M/year IBRD= $13.1M/Year HPC = $4.125M/Year
4 What is SCC? Self Consolidating Concrete (SCC) is concrete that does not require vibration to achieve full consolidation.
5 Traditional Concrete Construction Vibration necessary Labor intensive Skill dependent Quality varies
6 Poor Consolidation
7 Drilled shafts with congested reinforcement High slump concrete would not do it. SCC will work!
8 History of SCC Developed in Japan in the late 1980 s Motivations: Decreasing Availability of Skilled Labor Quality without Vibration Durable Structures European consortium formed in 1996 Use in Europe has grown rapidly since
9 The Three Key Characteristics of SCC Ability to flow into forms Ability to pass through reinforcement Resistance to segregation
10 Benefits of Self-Consolidating No Vibration Needed (Reduced Labor Cost) Less Noise Better Pumpability Concrete Reduced Wear on Equipment Faster Construction Improved Durability through Better Consolidation High Strength
11 Filling ability SCC Demonstration Passing ability Resistance to segregation
12 SCC Deck Pour
13 SCC Prestressed Girders Used in Japan

16 Applications of SCC in Japan Anchorages completed in 2 years rather than 2 ½ years!
17 Applications of SCC in Europe Cast time reduced by 35 40% Labor reduced by 50% No repair for defects

27 Self-Consolidating Concrete (SCC) 2001: Precast arch bridge 5,000 psi, 2,500 coulomb 2005: 8 Bulb-T beams 8,000 psi, 1,500 coulomb
28 SCC Beams Rte 33 (2005)
29 Smooth Surface Finish
30 Bugholes Rte 33 SCC Regular
31 What makes the Difference Same Basic Ingredients as traditional concrete Mix Design Admixtures Superplasticizer Viscosity Modifier
32 General Principles of Mix Design Limit the maximum size of aggregate Use a high ratio of fine aggregate to coarse Use a well-distributed aggregate gradation Use superplasticizer (polycarboxylate works best) Use viscosity modifying admixture (VMA) Use low water/cement ratio
33 Current Limitations Test Standards Limited experience Cost implications Structural design specifications Construction specifications
34 Performance Concerns Cracks Due to Shrinkage Resulting from the large amount of fine aggregate Pressure on Formwork Modulus of Elasticity Strand Bond Loss of Flowability due to: Hot Weather Long Haul Distance Delays at the Job Site
35 Guidelines and Specifications PCI Interim Guidelines for Self-Consolidating Concrete published in 2003 PCI SCC Guide Specification currently under development ACI Committee 237 SCC Standard of Practice ACI Committee 211 Proportioning SCC ASTM Test Methods Slump Flow, J-Ring and Column Segregation
36 SCC at Auburn University SCC in Drilled Shafts
37 Problems with Drilled-Shaft Concrete Conventional Concrete Self-Consolidating Concrete Debris Tremie Debris Tremie
38 Use of SCC for Drilled-Shafts SCC technology has great potential for drilledshafts as it may: offer high flowability through reinforcement cage reduce the amount of bleed water offer more resistance to segregation offer sufficient workability after extended times (6-10 hours) SCC may thus minimize some of the problems encountered in the past.
39 Proportions for Drilled-Shaft Applications Mixture Constituents SCC Conv. DSC Type I/II Cement 465 pcy 500 pcy Class F Fly ash 230 pcy (33%) 125 pcy (20%) Fine Aggregate, ASTM C 33 (SSD) 1,280 pcy 1,216 pcy Coarse Aggregate Amount (SSD) 1,616 pcy 1,811 pcy Coarse Aggregate Description No. 78 River Gravel No. 67 Water 284 pcy 270 pcy Extended-Set Control Admixture 6 to 10 fl oz/cwt 6 to 10 fl oz/cwt Mid-Range Water Reducer 4 fl oz/cwt - Polycarboxylate High-Range Water Red. 4 to 6 fl oz/cwt 4 to 6 fl oz/cwt Viscosity-Modifying Admixture (VMA) 2 fl oz/cwt - w/cm Sand/Aggregate (by volume)

46 Performance Specifications Workability Slump flow > 600 mm Remain flowable 90 minutes Withstand a slope of 3% Pumpable 90 minutes through pipes 100 m long
47 SCC Specifications Ohio DOT c. Provide fresh concrete for both the old mix and the new SCC mix for ODOT to produce shrinkage beams. Shrinkage tests will be performed on both mixes and compared. The SCC mix will not be allowed to exhibit more shrinkage than the old mix.
48 SCC Specifications Florida DOT Special Provisions issued December 2003 for Precast / Prestressed Concrete Products
49 FL DOT Special Provisions The slump flow spread shall be +2.5 in. of target. The Engineer may allow a maximum target slump flow spread of.. The difference between the slump flow spread with and without the J-ring shall be less than 2.0 in. [50 mm]. The slump flow time T 50 shall be between 2-7 sec. The VSI shall not exceed 2.
50 IL DOT SCC Specifications IL DOT QC/QA Program Addendum for Precast Concrete Products using SCC issued August 1, 2004 Defines Design Slump Flow Range, Product Slump Flow Range & Hardened VSI.
51 SCC Specifications Specifications should... Be realistic & practical Not overly restrictive Note that SCC is different from conventional HPC only in terms of its fluidity and ability to consolidate without the use of mechanical vibration.

53 Passing Ability: J - Ring Test (ASTM C 1621)
54 Slump Flow Test J-Ring Column Segregation
55 Performance Specifications Mechanical Properties 28 day comp. Strength = Similar to HPC Creep and Shrinkage = Similar to HPC Durability Freeze-thaw resistance HPC

59 NCHRP Study NCHRP Project SCC for PC, PS Concrete Bridge Elements: Deliverables: Develop properties and performance criteria Provide mix design recommendations Recommend Test Methods Fresh and Hardened Properties Durability characteristics Structural Design and Construction Specifications
60 Closing Remarks Design SCC to meet project needs: Teamwork and Coordination is Required between: Designer Specification Writer Materials Engineer Contractor Subcontractor/Supplier SCC has major technical and economic advantages
61 Can we afford not to consider SCC?
62 Good HPC But poor consolidation!
63 Good HPC, But poor consolidation! SCC would have cost too much?
64 Think SCC in your next project! Intricate and complex forms Congested reinforcement Architectural surfaces Precast/Prefabricated elements Quality and high productivity
