Factors Affecting The Expansive Stress / Pressure Of WONDER FISSURE
- The expansive stress can be increased to more than 11,200 T/m². (Fig. 1 & 3)
- The larger the hole diameter, the greater the expansive stress becomes. (Fig. 2)
- There is little change in the expansive stress when the water ratio is in the neighborhood of approximately 30%. However, the stress is decreased as the water ratio is increased or decreased.

Fig. 3 Changes in the expansive stress of CM - A
|a. The expansive stress developed by WONDER FISSURE reach a maximum value at about 24 hours of reaction. However it still keeps increasing slightly even afterwards.|
|b. The expansive pressure of WONDER FISSURE decreases as the water to WONDER FISSURE powder ratio increases. The optimum ratio is 0.30.|
|c. The expansive capabilities of WONDER FISSURE increases with increase in ambient operating temperature upto the maximum operating temperature.|
|d. The expansive power of WONDER FISSURE decreases with increase in the diameter of pre-drilled hole above the optimal value.|
