aci318-63
does anyone out there know what was the air-entrainment requirements for cast-in-place concrete in aci318-63?
any information is greately appreciated.

amokhta,
aci318-63 did not give explicit air contents for given f'c or aggregate size or exposure but it referneced aci 613 "recommneded practice for selecting proportions for concrete".
fyi - the '63 code was about 100 half-size pages - '02 is close to 500 full-size pages (including commentary)!
hth
ps aci international still sells the older codes - but all in print form, not pdf.
ingenuity:
thank you for the response.
best regards
