Enhancing Properties of Clay Mortars Using Nano-Additives
Earthen materials have been used in construction for centuries. Nowadays, a certain appeal towards natural materials rose again due to the various benefits they hold. Besides being inexpensive and approachable, earthen construction offers a clear sustainable method of modern manufacturing. Since earthen materials present high absorption and relatively low compressive strength, the main purpose of this study was to enhance these abilities of clay-based mortars using nanoadditives. To achieve the mechanical and physical invigoration of the clay matrix two different compositions were fabricated by the use of nanoclay, nanosilica and nanoalumina. The addition of nanoclay (NC) at 5%w/w of binder, indicated a lower water absorption and an increase in mechanical properties, while the use of nanosilica and nanoalumina combined at 1.5% and 1% w/w of binder respectively, outline a less stable and compact structure.
