Extruded fiver reinforced cementitious products having stone-like properties and methods of making the same

Abstract

A cementitious composite product that can function as a substitute for stone and solid surface materials, such as granite, marble, and engineered stone is provided. Furthermore methods for manufacturing the cementitious composite product using an extrudable cementitious composition that can be extruded or otherwise shaped into stone-like building products that can be used as a substitute for many known stone products is disclosed. In one embodiment, the cementitious composite products can be manufactured more cheaply to be as tough or tougher and more durable than stone and solid surface materials.

1 . A cementitious composite product having stone-like properties, the product comprising an extrudable cementitious composition comprised of a hydraulic cement,
 aggregate, a rheology-modifying agent, and fibers substantially homogeneously distributed through the extrudable cementitious composition and included in an amount greater than about 2% (by volume of the extrudable cementitious composition), wherein the cementitious composite product has a hardness value of at least 4 MOH and a bulk density of at from about 1.3 g/cm 3  to about 2.3 g/cm 3 .
