'Polycrete' is ACO's trade name for polymer concrete produced in Australia. It is a verstile, durable, composite material produced by mixing a variety of mineral fillers with a synthetic or natural resin binding agent. This advanced engineering material is used in many industries but is most common in the building and construction industries where its long life and material properties make it ideal for many products.
Material Features High resistance to chemical and biologocal attack Lightweight compared to cement concrete products Excellent noise and vibration absorption Excellent dielectric properties Good weathering and UV resistance Zero water absorption Can be cut with masonry drills and grinders Can be recycled as rubble or crushed for use as road foundation Approximately 4 times the flexural strength of cement concrete Good thermal properties and stability Ultra smooth finish which encourages efficient hydraulic flow     Material Properties     Bending strength Shear strenth Compressive strength Modulus of elasticity Specific gravity Water absorption Operating temperature Surface roughness Manning's coefficient 20 MPa 20 MPa 90 MPa 22,000 MPa 2,200 kg/m3 0.05% by weight up to 80°C 25 um 0.011   Polycrete Polycrete, also referred to as artificial granite, is a composite material consisting of dry aggregate fillers and a monomer system, polymerised in place by catalysed peroxide decomposition The principal components of Polycrete are gravel, sand and calcium carbonate bound together with a polymer resin. Commonly used in areas subject to heavy wear and high loadings such as carparks, roadways and industrial areas.   Hydraulic Performance The ultra-smooth internal surface gives superior flow characteristics (Manning's Co-efficient 0.011). When compared to conventional concrete or GRC, for a given cross-section, ACO Polymer Channels enable greater discharge rates to be achieved or longer lengths of channel to be installed. Chemical Resistance ACO Polymer Channels can be used in most environments where acids and dilute alkalis are likely to be encountered. ACO Chemical Channel should be specified for more aggressive situations; further details available upon request. Durability Polycrete has a very high compressive strength, but a little reasonable care is required in handling. Correctly specified and installed, ACO Drain products have a virtually unlimited design life.   Cleaning & Maintenance Polycrete as a material requires no maintenance and the channels are easily accessible for cleaning or maintenance of the drainage run. Mould Resistance Polycrete Channels require less maintenance than concrete channels. The smooth, impervious surface of Polycrete resists biological growth. HDPE Plastic High Density Polyethylene (HDPE) is an easily moulded plastic material making it ideal for the complex shapes of the ACO Cablemate plastic pit bodies. The resulting product is lightweight, durable and will withstand severe handling. HDPE is ideal for light duty applications, where the flexing of the material is not a major concern. High resistance to chemical and biological attack Lightweight Durable to withstand severe handling Easy to cut with drills and saws Zero water absorption Excellent dielectric properties Other Materials ACO uses a variety of different material for covers depending on the applications. Covers are available manufactured from Portland cement concrete, Polymer concrete, fabricated steel and stainless steel. When steel is used it is galvanised to the AS1650/1980 standard. The cover material is determined by cost, application and performance required. Home Page | CONTACT ACO NOW
