30MPa parking garage concrete slab vs. 35MPa 3

[ali07]

Hi Guys,

What are the consequences of a well designed 30 MPa parking garage concrete slab (exposed condition) vs. 35MPa required as per code. As the slab in question is low by 5 MPa, as per engineering judgement, is it necessary to demolish the slab or are there any means to improve the durability/permability of the concrete to reduce the anticipated cracking due to freeze/thaw.

Just curious, Zambo. Whose insurer are you talking about? Sounds like purely a technical issue to me with work underway to find a solution.

Zambo... the Contractor should have due to his exposure.

It's a good time to get a Cadillac system that may outperform the original specified deck just to be safe!
