Advances in clay-based mortars for protection against water penetration

Karozou Aspasia 1, Stefanidou Maria 1

Abstract


Earthen structures have been for centuries part of human history and civilization. However, the main threat of their endurance throughout time is their sensitivity against water. To overcome this problem, it is essential to focus on ways of increasing hydrophobicity as to shield against water penetration. This study focuses on new approaches based on nanotechnology and new generation materials as to protect clay based mortars against water intake. To increase their durability, two approaches were used. The first one was by introducing additives inside the clay matrix at various percentages, while the second approach was through surface treating agents without causing aesthetic changes. The results indicate the positive effect of most treatment methods followed in both approaches, while further investigation on the subject is held and encouraged.  


Keywords
