Effect of halloysite nanoclay on mechanical properties, thermal behavior and microstructure of cement mortars.

Many studies have targeted the application of clay in cement composites and declared some enhancement on the properties of concrete. However there is little knowledge on nanoclays and their effect on the mechanical properties and durability of cement composites. Halloysite nanoclay is one of the sub...
