High Performance Concrete Specifications

and Field Applications

Design Needs 1. Early Communication for Design

Performance Criteria Work with Industry Reps - Admixture, Cement,

Concrete Laboratories, Concrete Producers

2. Mix Design Development Test Trials- Lab or Field

3. Form Work Discussions with Industry Manufacturers

3. Specifications then designed around Concrete and Construction specifics needed

4. Allocation for Multiple Jobsite Mock ups. Especially if Architectural !!!

Field Performance NeedsPre-qualified Testing Laboratory-

12k psi, 14kpsi, 16kpsi and soon to be 20kpsi cannot be handled by just anyone

Laboratory Needs plenty of curing room storage Cylinder Grinding Machine Compression Machine able to handle 25,000psi

plusField Sampling unlike you have never seen before Curing Room Sea Container on site

Proper Cylinder making handling Self Consolidating Spreads of 30”+

Concrete NeedsState of the Art Chemicals- High Range

Waters Reducers, Set Controlling, Slump Retaining, Air De-Entraining

90 Minutes Need Not Apply- Prescriptive Concrete is replaced by Performance Concrete

Attentive Concrete Pumping- Stronger pumps, Modified Production

Seasonal Performance- Concrete will behave differently depending on season
