•  SOME EFFECTS ON THE EXPANSIVE STRESS OF STAFFII

1• The expansive stress of STAFFII reaches maximum force in about 24 hours of reaction.

However, it still increases afterwards.

2• The expansive stress of STAFFII will decrease if water ratio increases.

3• The expansive stress of STAFFII will increase with rising ambient temperature.


4• The expansive stress of STAFFII will increase if the diameter of pre-drilled hole is bigger.
