I. CHEMICAL COMPONENTS OF CHEMSHINE

CHEMSHINE is a powder consisting of an inorganic compound made mainly of a special kind of silicate and an organic compound. CHEMSHINE does not contain any harmful components.

II. SOME EFFECTS ON THE EXPANSIVE STRESS OF CHEMSHINE

1) The expansive stress increased more than, 6,000 t/m2. (Fig. 1, 3, 4)

2) The larger the hole diameter is, the greater the expansive stress becomes. (Fig. 2)

3) 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.
