Abstract:
PURPOSE: A porous artificial stone excellent in water absorption and ventilation is provided to use as stone on which plants grow or to landscape relief carving. CONSTITUTION: The porous artificial stone, looked like basalt, is manufactured by the following steps of: preparing mixed ash by mixing 50-90vol.% of activated carbon powder passing through a 1-500mesh sieve with 10-50vol.% of expanded pearlite powder passing through a 100-500mesh sieve, wherein zeolite, yellow earth, volcanic ash and elvan are optionally added; adding polyethers for rigid(or semi-rigid) urethane foam to the mixed ash and then adding isocyanate in a volume ratio of mixed ash/ polyol/ isocyanate of 0.8-1.8 : 0.4-0.6 : 0.4-0.6; mixing mixtures for 40-90sec in a rate of 2000-500rpm; pouring mixtures into a mold and covering a lid to the mold; hardening for 1hr and de-molding.

Abstract:
The invention relates to an agglomerate containing at least one of the following water-soluble or water-dispersible materials as a bonding base polymer: carboxylized and/or alkoxylized starch, cellulose ether and fully synthetic vinyl polymers and/or polyacrylates. The agglomerate is characterized in that it contains a disintegrant which produces a high swelling pressure, but, advantageously, does not gel. The agglomerate can have a regular geometric form or not. Its weight should be between 0.5 and 500g. The agglomerate is used in particular in the production of lump-free paste.
