Abstract
A cementitious product has an exposed surface finish which is applied during formation of the product by a pressing process and which simulates the surface and aspect of natural stone provided by secondary processing.
Claims12
A method of manufacturing a cementitious product having exposed aggregate coarse particles, said method comprising the steps of:
- preparing a cementitious mix incorporating fine particles including sand and cement, aggregate coarse particles and water;
- and
- pressing a flowable mass against a surface of said cementitious mix to clean fine particles from aggregate coarse particles adjacent to said surface of the cementitious mix and to form a pressed cementitious product of which said surface has cleaned exposed aggregate coarse particles standing proud of said fine particles.
A method of manufacturing a cementitious product having exposed aggregate coarse particles, said method comprising the steps of:
- preparing a cementitious mix incorporating fine particles including sand and cement, aggregate coarse particles and water;
- pressing a flowable mass against a surface of said cementitious mix;
- said flowable mass:
- initially acting to compact said cementitious mix until the aggregate course particles are in a close packed arrangement;
- and
- further acting by applying continued pressure that deforms said flowable mass causing said flowable mass to flow around uppermost aggregate coarse particles and uppermost fine particles to be driven into areas between said aggregate coarse particles;
- whereby to clean fine particles from aggregate coarse particles adjacent to said surface of the cementitious mix and to form a pressed cementitious product of which said surface has cleaned exposed aggregate coarse particles standing proud of said uppermost fine particles.
