Abstract
The invention relates to a method for the production of concrete blocks or concrete slabs of varying formats and sizes, whereby concrete is filled into molds for several blocks or slabs, the surface layer of which or the facing concrete layer of which has a base color and the surfaces, which have regions of difference colors, is puddled by means of vibration and/or compacting and subsequently hardened, whereby, before puddling, at least one portion of a pigmented and/or variously-pigmented and/or a color- and/or various color-containing finishing material is projected or thrown by means of at least one application device.
Claims27
A method for fabricating concrete blocks comprising the steps of:
- providing a plurality of molds,
- charging raw concrete into said molds forming blocks;
- applying to each block of said blocks a surface layer wherein said surface layer has a fine-grained adapted grain structure not greater than screen cut C4,
- throwing at least one portion of a pigmented finishing material on said surface layer of said formed blocks by at least one applicator to produce colored places simulating natural rock wherein said finishing material has a graded granulometric composition having a maximum grain diameter of 2 mm,
- compacting and vibrating said blocks, and
- curing said blocks.
A method for fabricating concrete blocks comprising the steps of:
- providing a plurality of molds,
- charging raw concrete into said molds forming blocks, each of which has a surface layer wherein said surface layer has a fine-grained adapted grain structure not greater than screen cut C4,
- throwing at least one portion of a pigmented finishing material on said surface layer of said formed blocks by at least one applicator to produce colored places simulating natural rock,
- compacting said blocks, and
- curing said blocks wherein said applicator has at least one centrifugal feeder disk to which said at least one portion of said finishing material is supplied and wherein said applicator has at least one metering vessel containing a finishing material and having a metering strip, said metering vessel being guided over said molds.
A method for fabricating concrete blocks comprising the steps of:
- providing a plurality of molds,
- charging raw concrete into said molds forming blocks, each of which has a surface layer,
- throwing at least one portion of a pigmented finishing material on said surface layer of said formed blocks by at least one applicator to produce colored places simulating natural rock,
- compacting said blocks, and
- curing said blocks wherein a plurality of applicators are utilized for one of said molds and wherein a plurality of applicators (4) are utilized for one of said molds.
