class a and aa concrete properties
hi,
does anyone know the properties of class a and aa concrete
properties (stength and young's modulus)? thanks in advance.
jack
it seems to me that you would need to indicate the appropriate agency involved in order to get your answer. different agencies can have their own concrete class designations and their own specifications.
thanks, peinc.
i am doing a fem analysis on bridge approach slab and would like to have resonable properties for the concrete slabs normally classed as "a" and "aa".
jack
again, who is the specifying agency?????  penndot's class a or aa may not be the same as some other agency's class a or aa.  i am not aware of a universal designation for concrete classes.
