Impregnating with quality silicone water repellent on the concrete surface is an effective method of protectingconcrete. Quality silicone water repellent has been widely used in the engineering profession because ofits desirable properties such as hydrophobicity, keeping concrete breathable and preserving the originalappearance of the concrete. The companies in China that produce silicone water repellent are listed. Testmethods in the specifications or standards about silicone water repellent in China are summed. The testmethods relative to durability of concrete impregnated with silicone water repellent (such as resistant tochloride ion penetration, resistant to alkali, resistance to freezing and thawing and weatherability etc.) andthe constructive quality (such as water absorption rate, impregnating depth and the dry velocity coefficientetc.) are compared and analyzed. The results indicate that there are differences among test methods relativeto different specifications with the same index and therefore, confusion has ensued when selecting testmethods. All test methods with the exception of the method of water absorption rate by using a Karstenflask are not non-destructive methods or conducted in a laboratory. Finally, further research on siliconewater repellent during application is proposed.
