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. | ||||
