Sažetak
The focus of this paper is on the results of
investigation conducted to find strength
relationships in foamed aerated concrete in which
cement has been partially replaced by pulverized
cow bone by weight, up to 20 % at interval of 5 %.
Concrete beam specimens of dimension 150 x 150
x 750 mm were used for the modulus of rupture test,
while cylinder specimens 150 x 300 mm were used
for the splitting tensile strength test. Compressive
tests were carried out using 150 x 150 x 150 mm
cube specimens. The results showed that (i) both
the ratio of splitting tensile strength to compressive
strength, and modulus of rupture to compressive
strength were decreased with an increase in the
replacement of cement with pulverized cow bone,
(ii) both the ratio of splitting tensile strength to
compressive strength, and modulus of rupture to
compressive strength increased with curing ages.
Also, the expressions relating splitting tensile
strength and the modulus of rupture with
compressive strength of foamed concrete
containing pulverized bone as partial replacement
of cement yielded results that compared well with
the experimental data.
