    摘要: Radical polymerization-curing working material compositions having a prolonged working life which contain the following components (a) to (e): (a) a polymerizable unsaturated monomer; (b) a polymer being soluble of dispersible in the above component (a); (c) a radical polymerization initiator; (d) a transition metal soap; and (e) a compound capable of forming a complex or a chelate with the transition metal in the above component (d). These compositions are applicable at from low temperatures (about - 20 DEG C) in winter to high temperatures (about 70 DEG C), in particular, on the road surface in summer, etc.

    摘要: Chromates are produced from chromium traces in the starting components of cements because of oxidation by air at elevated temperatures during the production of cement and later adding water in order to produce cement mortar. Said chromates irritate the skin, cause allergies, and are possibly carcinogenic. The invention relates to a method and a substance for the reductive chromate detoxification of cement preparations by means of manganese(III) salts that are soluble in water at a pH exceeding 7. Also disclosed is the use of manganese(III) salts to reduce Cr(VI) compounds in cement preparations.
