Abstract
This part of research program investigates the influence of applying the widely used
additives, such as accelerators (Calcium Chlorides CaCl 2 ), Inhibitors (Sodium Nitrite
NaNO 2 ), and Water Reducing Agents (Super -Plasticizer) on the Mechanical
properties of concrete; The Uniaxial Compressive Strength, Absorption of water, and
Disintegration of concrete at different time intervals, to introduce an imagination of
concrete behavior when chemicals are used. These additives were varyingly added to
plain concrete cube samples. Meanwhile control mixes out of the interference of
chemicals were prepared simultaneously, to deduce a rational conception about the
best behaving mix against harmful surrounding conditions. A mathematical treatise
was discussed from the experimental data to interpolate the results of each category
for each test.
The essence of this research surpasses the straightforward announcement for the
advantages of additives to a balanced comparison between benefits gained and the
undesirable sequences resulted from .It has been found that the use of certain
substances inevitably brings problems to concrete durability against aggressive
circumstances (results indicate that mixes contain sulfates fail quickly under the
disintegration of concrete test despite the prior strength oftenly noticed). The use of
aim-contradicting subjects gives high resistibility against corrosion of reinforcement
[1]. But it doesn't commensurate with the damage of corrosion (disintegration) of
concrete itself. So, results as well as mathematical manipulations give us an
evaluation of how additives act and a prediction of their future effect on concrete.
