Abstract
There is disclosed a softy mud solidifying agent which comprises cement, and at least two members selected from the group consisting of pozzolanic substances, inorganic compounds and organic compounds. The solidifying agent is capable of solidifying dredged earth, sand, softy mud, etc. in such a manner that their mixture can be re-cast into water to form submerged banks, artificial fish-gathering places, etc., without causing water pollution.
Claims2
A softy mud solidifier comprising:
- (a) cement as the principal component,
- (b) an inorganic compound, and
- (c) a mixture of a pozzolanic substance and an organic compound,
- said inorganic compound being one or more members selected from the group consisting of
- (i) lime and gypsum,
- (ii) calcined dolomite,
- (iii) calcium salts,
- (iv) sulfates, and
- (v) iron oxides,
