Abstract
Disclosed is a highly reactive hydraulic binder for the preparation of building, construction and raw materials which contains burned oil shale and at least one compound, selected from the group, consisting of an amorphous oxide of 3- and/or 4-valent cations, an amorphous hydroxide of 3- and/or 4-valent cations, and an aluminate of 1- and/or 2-valent cations, as well as at least one water reducing agent.
Claims19
A highly reactive hydraulic binder for preparing building, construction and raw materials, said binder comprising (i) burned oil shale, (ii) at least one member of the group of amorphous oxides of 3-valent cations, amorphous oxides of 4-valent cations, amorphous hydroxides of 3-valent cations, amorphous hydroxides of 4-valent cations, aluminates of single valent cations and aluminates of 2-valent cations, and (iii) at least one water reducing agent;
- said components (i), (ii), and (iii) being present in amounts effective to provide a hydraulically hardenable binder.
A process for hardening a highly reactive binder, said process comprising (i) mixing said binder with an effective mixing amount of water, wherein said binder comprises (a) burned oil shale, (b) at least one member of the group of amorphous oxides of 3-valent cations, amorphous oxides of 4-valent cations, amorphous hydroxides of 3-valent cations, amorphous hydroxides of 4-valent cations, aluminates of single valent cations and aluminates of 2-valent cations, and (c) at least one water reducing agent, and (ii) hardening the mixture.
A highly reactive hydraulic binder suitable for preparing building, construction and raw materials, said binder comprising:
- 1-99.3% by weight burned oil shale;

- 0.01-10% by weight of at least one water reducing agent;
- 0.01-7% by weight of at least one setting retarding agent;
- 0.1-50% by weight of at least one member of the group of amorphous oxides of 3-valent and 4-valent cations and amorphous hydroxides of 3-valent and 4-valent cations.
- up to 90% by weight of cementous material;
- up to 30% by weight of a polymeric material;
- and
- up to 20% by weight fiber material.
