Indicative Test Results
Slip resistance (AS/NZS 4586-2004) - 51W (risk of slipping when wet = low)
Flexural strength - dried (ASTM C880) - 5.5 MPa
Flexural strength - wet (ASTM C880) - 4.0 MPa
Density (ASTM C97-02) - 2226 kg/m3
Water absorption (ASTM C97-02) by volume (porosity) - 9.5%
Water absorption (ASTM C97-02) by weight - 4.3%
Resistance to salt attack weight loss (AS/NZS 4456.10) - 5.8%
Resistance to salt attack classification (AS/NZS 4456.10) - C (not suitable for frequent wet, dry & salt attack cycles, therefore not recommended for use around swimming pools or water features)
Resistance to salt attack (AS/NZS 4456.10) mode of decay - moderate to severe surface pitting, therefore not recommended for use around swimming pools.
NB The benchmarks for use of stone around salt water pools is 0.1% weight loss or less with a minimum slip resistance classification of W.
