The experiment researches prove that the addition of the antiseptic, rust inhibitor and permeation resistance agent in the concrete is the simplest and economical effective measure.

Through permeability resistance test, sulfate corrosion test and abrasion resistance test, the relationship of construction techniques, concrete surface quality and durability was reached.

The text overpass test to co (?) firm the effect of the three kind of cement based capillary crystalline waterproof material Xypex, Naishen, JL, which can modify the strength.
