Impact of Penetrating Sealers and Internally Mixed Hydrophobic Compounds on Durability of Concrete

Durability of concrete is greatly impacted by infiltration of water into its pores. Utilizing penetrating sealers can help improve the concrete’s durability. Penetrating sealers come in a variety of forms, but the most common are silane and siloxane. This thesis will explore the impact of these, as well as other surface treatments on the durability of concrete. Silane was also tested as an admixture to observe behavior as an integrally mixed compound. Conclusions are drawn from contact angle, depth of penetration, absorption, and degree of saturation results. Silane and soy methyl ester are the most effective at improving the durability concrete out of the treatments tested. Each showed increased depth of penetration. Both also decreased absorption rates and increased time to critical saturation. Integrally mixed silane at recommended doses did not show improvement in durability, but is worth investigating further. Evaluation of field samples showed that silane is also effective at improving the durability of concrete joints. However, it does not necessarily prevent joint deterioration due to spalling.
