As it is known, one of the methods used to prevent corrosion
in reinforced concrete structures is corrosion inhibitors. It is also possible
for structures using inhibitors to encounter different environmental
conditions. Different environmental conditions may adversely affect the
strength and durability of the cement mortar structure. In this study, the
effects of commercial corrosion inhibitors containing calcium nitrite
(Ca(NO2)2), which is defined as inorganic, on the mortar structure under the
influence of sulfate, were investigated, taking into account environmental
conditions. In the study, 40x40x160 mm mortar samples were produced by using
crushed stone sand (0-4 mm) and CEM I 42.5 R Portland cement obtained from
Eskişehir region. The water-cement ratio was designed to be 0.50 in each sample
series. The amount of inhibitor added to the mortar mixture was used as 0%, 1%
and 2% of the cement dosage. Standard curing was applied to the produced
samples for 28 days. Standard curing was applied to the produced samples for 28
days. The samples, whose curing period is completed, are kept in 5% Na2SO4
solution for 7, 28 and 90 days. The applied solution is renewed every 15 days.
The compressive and flexural strengths, unit weights and ultrasonic pulse
velocity of the samples held under the influence of sulfate were investigated.
In the study, it was determined that the compressive strength of the samples
using 1% inhibitor was 2.27 % higher than the samples without inhibitor under
the 90-day sulfate effect, and the optimum use of 1% inhibitor was appropriate.
