Concrete Mix Design
Concrete Mix Design
(OP)
I am looking for information or experience with low drying shrinkage concrete. I am specifying an industrial type floor slab. The owner has had material handling operation issues with their current floor slab at the joints.
This will be a floor slab in an addition. I am reviewing the joint design and lay-out as well as the concrete mix design.
The goal is to have little or no curling at the concrete joints. Predictable joint sizes prior to filling/sealing.

Also, if you like you may specify type-K cement, which is shrinkage compensating in nature. You also can specify shrinkage compensating admixture for your mix.
You may need to pay spacial attention to curing of the concrete. If you do not like cracking or curling at all then you may have to prescibe longer curing period. You have to select the amount of reinforcement and spacing of contraction joints more carefully.

This pour was in a closed building and it looked like they were taking extra care in curing of the concrete.
