Abstract

ABSTRACT:- This research was studying the effect of added aluminum fiber from the
waste product of aluminum factories on the properties of concrete mixes. The study involved
a reference concrete mix (M0) without admixture of aluminum and compare with three mixes
(M3,M5,and M10) ,with three percent (3%,5%, and10%) from weight of cement, Specifically
The thermal conductivity factor (k) was calculated depending on the equation of ACI code
(122-R-2002) for mix concrete. The laboratory testes (slump flow, density, compressive
strength) were doing for the cubes samples with dimension (150*150*150) to concrete
mixes(M0,M3,M5),and M10) in age (7,14,and 28)day. The affect thermal conductivity factor
of concrete was depended on the effect of workability, density and compressive strength with
age sample. The results were getting from the testing found the density ,thermal conductivity
factor and compressive strength decreasing with adding the admixture of aluminum (7%-
20%),(17%-45%) and (30%-54%) respectively, because of the reaction between the
aluminum fiber with compound of cement cause the babble gas (Cellular concrete ) due to
reduction in the density and compressive strength .
