  1. TEST METHODS AND RESULTS

 

  • Water absorption & bulk specific gravity

 

Five specimens were tested in accordance with ASTM C97 – 02.

 

Detailed test results are given in Table 1 and are summarised in the table below.

Sandberg Water Absorption Bulk Specific Gravity
Reference (%) (kg/m3)
Range Mean Range Mean
G34878 0.07 – 0.13 0.11 2716 – 2736 2722

  • Compressive strength

 

Specimens were tested in accordance with ASTM C170 – 90 (1999).

 

Twenty specimens were tested with the load applied in an unknown bedding direction, with ten tested after oven drying for at least 48 hours and ten after saturation in water for at least 48 hours in each case.

 

Detailed test results are given in Table 2 and are summarised in the table below.

G34880 Unknown – wet 49.56 – 139.96 108.93

  • Modulus of rupture

 

Specimens were tested in accordance with ASTM C99 – 87 (2006).

 

Twenty specimens were tested with the load applied in and unknown bedding direction, with ten tested after oven drying for at least 48 hours and ten after saturation in water for at least 48 hours in each case.

 

Detailed test results are given in Table 3 and are summarised in the table below.
