Abstract

 

Aim: To improve the life of concrete by surface modifications and to increase hydrophobic nature of concrete by porosity reduction through rice husk coating.    

 

Methodology: Rice husk ash was dispersed in ethanolic solution containing fluoroalkyl silone to prepare super hydrophobic coating. This solution was sprayed on the layer of commercial adhesive coated on the concrete.

 

Results: Water contact angle of 150.3 was observed on the coated concrete. The cumulative water uptake was reduced up to 40.38%.    

 

Interpretation: Super hydrophobic coating on concrete requires roughness which was created by silica particles in the rice husk. Penetration of water into the coated concrete was successfully reduced, but did not prevent completely. The coating did not affect the surface hardness or the compressive strength, but surface porosity was reduced.

 

Key words: Hydrophobicity, Modified concrete strength, Porosity, Rice husk
