Simulating Natural Stone.
Cast stone is a blend of ground-up natural stone, coloured cement, sand, and reinforcing fibre. Forms are produced by casting mixtures into designed moulds to create a broad range of window dressing and trim, terrace railings, doorframes, entranceways, and exterior wall coverings. Cast stone suggests aesthetic elegance, offers character, plus it will not deteriorate. Complements stucco, brick cladding, and any natural stone veneer. Cast Stone can be used for architectural trim elements, facade, and moulding, including columns for your next project. It can be cast in a wide range of colours and stone finishes. Unlike some materials, weathering tends to improve the appearance of cast stone over time, helping it appear more natural. Moreover, it can be reinforced, allowing it to have both the structural advantages of concrete and the aesthetics of natural cut stone. Since cast stone is a heavy product, it is anchored into wall systems and used as an architectural feature, on commercial and residential buildings.
CAST STONE VS PRECAST CONCRETE
Cast stone is a version of precast concrete consisting on fine aggregates, water reducing admixtures and a higher strength than traditional precast. The Cast Stone Institute defines cast stone as having a minimum strength of 6500 PSI (45 MPa).
Sanderson Concrete’s standard precast concrete typically exceeds 42 MPa – and our cast stone will often exceed 60 MPa. Mix strengths are often determined by aggregates and pigments – however softer aggregates can be allowed for with careful gradation and proper use of chemical admixtures and water reducers.
