  1. Presentation Summary • Company History • Concrete Basics • USCP’s Product Line / Highlights • Manufacturing Plant • Questions

  2. US Concrete Products • Started in 2000 • Principals’ background with the Sakrete Company • Did all company specialty product mix designs

  3. Concrete Basics • Its as simple at 1-2-3 • 1 part cement meeting ASTM C 150, 2 parts concrete sand meeting ASTM C 33, 3 parts coarse aggregate meeting ASTM C 33

  4. ASTM Designations – Why they are important • Cement meeting ASTM C 150 assures the proper chemical make up for consistency in performance and long term durability • Foreign imported cements can be cheaper but you don’t know exactly what you are getting from shipment to shipment

  5. ASTM Designations – Why they are important • Aggregates meeting ASTM C 33 gradation requirements assures the proper particle size distribution • Proper particle sized distribution is critical to produce concrete with long term durability

  6. ASTM C 33 – Concrete Sand Sieve (Specification E 11) Percent Passing 9.5-mm (3⁄8-in.) 100 4.75-mm (No. 4) 95 to 100 2.36-mm (No. 8) 80 to 100 1.18-mm (No. 16) 50 to 85 600-μm (No. 30) 25 to 60 300-μm (No. 50) 5 to 30 150-μm (No. 100) 0 to 10

  7. ASTM C 33 – #8 or 3/8” Aggregate Sieve (Specification E 11) Percent Passing 12.5-mm (1/2-in.) 100 9.5-mm (3/8-in.) 85-100 4.75-mm (No. 4) 10-30 2.36-mm (No. 8) 0-10 1.18-mm (No. 16) 0-5 600-μm (No. 30) 300-μm (No. 50) 150-μm (No. 100)

  8. Total Particle Size Distribution • 7 different sizes total between 3/8” #50 sieve • Cement fills the voids between the particle sizes

  9. Total Particle Size Distribution – Why is this important? • The matrix created helps assure the long term durability of the concrete • Assures water addition is not excessive – too much fine aggregate needs more water • Optimizes the use of materials

  10. Typical Sand Gradation – Competitors use Sieve (Specification E 11) Percent Passing 9.5-mm (3⁄8-in.) 100 4.75-mm (No. 4) 100 2.36-mm (No. 8) 100 1.18-mm (No. 16) 50 to 85 600-μm (No. 30) 30 to 40 300-μm (No. 50) 0 to 10 150-μm (No. 100) 0

  11. Why do they use this gradation? • Most of the major suppliers have their sand dried by another company • The sand used is conveyed pneumatically • Multiple particle sizes as defined by ASTM C 33 would segregate in the pnuematic conveying process

  12. How do we know this? • USCP dries aggregate for major competitors

  13. What are full depth concrete repair materials? • Full-Depth Repairs • 4.0 Material Considerations • Typical full-depth repair operations utilize concrete mixes containing 390-502kg/m3 (658-846 lbs/yd3) of either cement Type I or Type III cement. A set-accelerator is frequently used to permit opening in 4 to 6 hours. . . . Regardless of the mix design used, the concrete mixture for full-depth repairs should have the following properties: • 6.5 ± 1.5 percent of entrained air in the concrete (less air may be permissible in nonfreeze areas). • 50 to 100 mm (2 to 4 in.) slump • Mixes using Type III cement may require slightly more mix water than a similar mix with Type I portland cement. However, too much extra water may cause the concrete to suffer from high shrinkage during curing. A water-reducing admixture will disperse cement particles and reduce the water necessary for workability. Above can be found at http://www.fhwa.dot.gov/pavement/full4.htm .

  14. Deck Mix line for full depth repair • Engineered concrete in pre-packaged form • Single component • Graded coarse & fine aggregates for proper particle-size distribution • ASTM C33 concrete sand with gravel meeting ASTM #8 (3/8”) • AE - 80lb. bag, .61 cu.ft. • FP – 50lb. Bag, .42 cu.ft. (neat) .52 cu.ft (ext) • Air-entrained • Corrosion inhibitor

  15. Full Depth Repair Deck Mix AE & FP • Deck Mix AE – Air Entrained Concrete with Corrosion Inhibitor • Deck Mix FP – Air Entrained with Corrosion Inhibitor, designed specifically for form and pump applications

  16. Just add water Contains gravel Air entrained 6” slump at time of placement Water/Cement ratio of .37 Shrinkage Compensated Corrosion Inhibitor Features of Deck Mix AE & FP:
