This research presents an empirical relationship between modulus
of elasticity with compressive strength concrete that is prepeard
from localized materials and containing several perecentages of
natural pozzolan (0 ,10 ,15, 20)% , also for tow cem
ent quantity
(350 ,400 ) Kg/m3 and for tow ages(28 ,90 ) day .Then comparing
the experimentally obtained result with the mechanical properties
calculated using the recommend relationship from the various
design codes. A new empirical relationship between elastic
modulus, and compressive strength for concrete containing natural
pozzolan is proposed.
