on technical notes now.

Business
• Bill Phelan – Concrete slabs over vapor retarder field testing:
Not enough data to make an industry statement. It looks like 0.04%
shrinkage on poly is “no problem”. Per Harrison, dominant joints
are a big issue and this committee needs to address it. Neuber may
have a project that is measureable. McPhee has had recent
experience using extended jointing (with steel fibers) at 75 to
100’ with minimal curling.
• Dennis Ahal – Finishing lightweight concrete: Deny provided a
summary of finishing problems related to air entrained concrete and
cautioned that specifying higher F numbers require enhanced
finishing equipment use which may lead to delamination
issues.
• Peter Craig – Avoiding moisture related problems: No ongoing
research – should be ready within several months
• Pat Harrison – Liquid surface treatment standard: Need to get
going ahead with this. Will revitalize it with chair..
