Concrete Creep Coefficient
Concrete Creep Coefficient
(OP)
What is the normal range for concrete creep coefficient (sometimes called creep factor) as defined in EC2 Clause 7.4.3?

RE: Concrete Creep Coefficient
The long term creep coefficient is just the basic coefficient multiplied by the final coefficient.

has a function that will return creep and shrinkage coefficients to AS 3600 or EC2. There can be quite large differences between the two.

RE: Concrete Creep Coefficient
Is there a main reason why AS3600 can be almost double the value of EC2?
RE: Concrete Creep Coefficient
I guess it could mainly be due to the local aggregates ?
I had a look at the AS3600 page 40, there is a factor dependent on the hypothesis thickness,
which seems significant.
If I design a 1-m width of a floor slab, should I use the full perimeter of the slab ? or just should use the sides which expose to the atmosphere (i.g. only top and bottom for calculation of perimeter "u") ?
