Re: Concrete Density

[Subject Prev][Subject Next][Thread Prev][Thread Next]


The lateral pressure of wet concrete can be a little tricky as it is affected by a lot of variables such as the original slump, temperature, w/c ratio, add mixtures that retard or accelerate, and the rate of placement such as in a large tall column.  If you are seriously designing formwork I would suggest looking at ACI-347R, "Guide to  Formwork for Concrete" which has very good guidelines and formula for lateral concrete pressures and other suggestions for additional live loads.

I have a couple general concrete questions.  1) what is the density of cured concrete in a saturated state?  (i.e. a saturated sidewalk)  2) do concrete roof tiles increase in weight substantially when wet?  3) what is the approximate equivalent lateral pressure of a concrete mix against formwork?  Thanks for any input.
