Method for the production of granular materials designed to be used as aggregates and fillers in a mix containing a binder for the manufacture of articles in slab or block form. The method comprises a step of melting a mixture of selected minerals having a specific chemical composition, a step of casting the molten material, a step of cooling the cast material until a predetermined temperature is reached and a step of crushing and/or grinding the cooled material to obtain granular materials having a selected particle size and suitable for use as aggregates or fillers in the mix for the manufacture of articles in slab or block form. Moreover, the method comprises, upstream of the melting step, a step for recovery and collection of the manufacturing waste of other previously manufactured articles. The manufacturing waste is designed to compose at least partially the mixture of selected minerals. The invention also relates to a method for manufacturing articles in slab or block form from a mix containing the aggregates and the fillers and a binder.

A knitted spacer fabric has a tightly knitted bottom layer, a more loosely knitted upper layer and linking fibres extending across the space between the lower and upper faces. Settable material, e.g. cement, is introduced into the space between the upper and lower faces and can be caused to set by the addition of a liquid, e.g. water. Until set, the fabric is flexible and can be shaped but after the material in space has set, the fabric is rigid and can be used as a structural element in a wide range of situations. The bottom layer has an extension that extends beyond the upper face and is connected to the upper face by elastic connecting fibres that draw the extension towards the other face, thereby at least partly closing the space at the edge of the cloth and preventing the settable material from spilling out. In addition, the packing of the settable material and maximum space between the faces are such that only a predetermined amount of liquid can be accommodated within the space and that amount is matched to the water required to set the cement.

The invention relates to an environment-friendly artificial stone with low cost and high strength and a preparation method thereof, the artificial stone comprises the following raw materials in parts by mass: 60-80 parts of fritted sand; 10-30 parts of quartz powder; 9-14 parts of terephthalic unsaturated polyester resin; 0.6-1 parts of curing agent; 0.8-1 parts of coupling agent; 0.5-1 parts of pigment paste; 0.1-1 parts of pigment powder.
