Abstract—The Concrete is today’s main building material. Our age of globalization requires a stable and fully-functional infrastructure that connects people and markets. This infrastructure is based on concrete. Modern road and bridge construction would be inconceivable without concrete, as would skyscrapers and industrial buildings. Bigger, higher, wider the global construction boom constantly sets new challenges for materials and technology, as the size and number of buildings increase. That’s why concrete will remain the Number one building material in the future. The Water is the primary agent of deterioration and cause of many physical processes of deterioration, or it can be a vehicle for transport of aggressive ions which cause chemical process of deterioration. The movement of water in concrete is controlled by the permeability of concrete. Permeability is the most important indicator of durability of concrete. The Concrete is a versatile building material, used especially in civil engineering in combination with steel. However, concrete and steel are vulnerable to harmful substances that penetrate into the building material by means of moisture. This can result in costly concrete damage due to reinforcement corrosion. This is an undesired characteristic and can lead to deteriorating outcomes, affecting its physical functionality, aesthetics and durability in service life. The Only effective preventive measures such as hydrophobic impregnation provide reliable protection for concrete structures in turn prolong service life and durability. Thus in the present investigation an attempt has been made to study the effectiveness and performance of Impregnate material on rate of flow of water in concrete with two different Grades of concrete and hydrophobic impregnates by conducting RILEM tube test method. Results will provide comparative data to analyze and determine the difference in performance between the impregnate materials, and identify the most effective performing agent.
