MULTILAYER CEMENTITIOUS STRUCTURE

摘要

The multilayer structure disclosed comprises an upper layer and a lower laye r both made of a cementitious matrix. An intermediate layer made of a non-wove n fibrous material and filled with a non-cementitious filling material is sandwiched between the upper layer and lower layer. The structure may advantageously comprise a plurality of intermediate layers included in a cementitious matrix. Among other things, adding a product inside the fibrous layer may reduce the weight of the structure and avoid contact between the different cement layers, thereby providing numerous advantages.
