Abstract
Techniques are described for treatment of ash and paper to eliminate them from the environment and to produce ceramic particles useful as light-weight aggregate (e.g., for use in concrete products). The ash may be that resulting from incineration of rubbish or sewage sludge or it may be fly ash from power plants. The ash and waste paper are mixed with clay and water, shaped into desired shapes and sizes, after which the particles are fired to produce ceramic particles which are lighter in weight than natural aggregates.
Claims20
A process for making ceramic particles comprising the steps of:
- (a) forming a suspension of clay in water;
- (b) adding ash and fibrous organic matter to said suspension;
- (c) reducing the water content of said suspension to less than about 60% by weight to form a sludge;
- (d) shaping said sludge to form particles of desired size and shape;
- and
- (e) firing said particles at a temperature and for a time sufficient to form ceramic particles.
A process for making ceramic particles comprising the steps of:
- (a) forming a suspension of clay in water;
- (b) adding ash and organic matter to said suspension, wherein said organic matter comprises paper;
- (c) reducing the water content of said suspension to less than about 60% by weight to form a sludge;
- (d) shaping said sludge to form particles of desired size and shape;
- and
- (e) firing said particles at a temperature and for a time sufficient to form ceramic particles.
A process for converting ash and paper to ceramic particles comprising the steps of:
- (a) forming a suspension of clay in water;
- (b) adding said ash and said paper to said suspension;
- (c) reducing the water content of said suspension to less than about 60% by weight to form a sludge;
- (d) shaping said sludge to form particles of desired size and shape;
- and
- (e) firing said particles at a temperature and for a time sufficient to form ceramic particles.
