Starting Time:   5:00 PM PST

End Time:   8:00 PM PST

Sponsor(s): ACI Southern California Chapter

Description:
Compressive strength tests are used for concrete acceptance based on criteria defined in ACI 318 and ACI 301. Tests results not meeting these criteria are referred to as low strengths. This presentation covers the “low strengths” topic in detail and provides answers to questions such as:
what is considered a strength test and what is not, what the minimum frequency of testing is, what the acceptance criteria for strength tests are, and how to investigate strength tests not meeting the acceptance requirements. In addition, steps needed by a concrete supplier, in case acceptance criteria are not met, will also be discussed.
