Decorative panel, and decorative floor covering consisting of said panels

A decorative panel, in particular a floor panel, ceiling panel or wall panel, comprising:

• a core layer having an upper side and a lower side,
• a printed decorative top layer connected, directly or indirectly, to said upper side of the core layer,
• a first panel side edge comprising a first coupling profile, and a second panel side edge comprising a second coupling profile designed to interconnect with a first coupling profile of a second, identical panel, both in horizontal direction and in vertical direction, wherein the first coupling profile comprises:
• an upward tongue,
• at least one upward flank lying at a distance from the upward tongue,
• an upward groove formed in between the upward tongue and the upward flank wherein the upward groove is adapted to receive at least a part of a downward tongue of a second coupling profile of another, identical panel, and
• at least one first locking element provided at a distant side of the upward tongue facing away from the upward flank,
• and wherein the second coupling profile comprises:
• a first downward tongue,
• at least one first downward flank lying at a distance from the downward tongue,
• a first downward groove formed in between the downward tongue and the downward flank, wherein the downward groove is adapted to receive at least a part of an upward tongue of a first coupling profile of another, identical panel, and
• at least one second locking element adapted for co-action with a first locking element of the other identical panel, said second locking element being provided at the downward flank,
• a third panel side edge comprising a third coupling profile, and a fourth panel side edge comprising a fourth coupling profile designed to interconnect with a third coupling profile of a another, identical panel, both in horizontal direction and in vertical direction, wherein the third coupling profile comprises:
• a sideward tongue extending in a direction substantially parallel to the upper side of the panel,
• at least one second downward flank lying at a distance from the sideward tongue, and
• a second downward groove formed between the sideward tongue and the second downward flank,
• wherein the fourth coupling profile comprises:
• a third groove configured for accommodating at least a part of the sideward tongue of the third coupling profile of a second identical panel, said third groove being defined by an upper lip and a lower lip, wherein said lower lip is provided with an upward locking element,
• wherein the third coupling profile and the fourth coupling profile are configured such that the third and fourth coupling profiles of two identical panels can be coupled to each other by means of a turning movement, which involves at least a part of the sideward tongue of a first panel being inserted into the third groove of the other identical panel, and wherein at least a part of the upward locking element of the other panel is inserted into the second downward groove of the first panel,
• wherein the core layer comprises at least one layer of foam concrete which is constituted by a matrix of concrete material in which air pockets in the form of cells are present,
• wherein the panel thickness is between 3 and 10 mm,
• wherein the concrete material comprises a particulate material comprising cellulose based particles,
• wherein the core layer comprises at least one reinforcement layer, wherein the at least one reinforcement layer comprises a textile layer, a cellulose layer, a carbon fibre layer, a glass fibre layer, or a combination thereof, and
• wherein the core layer comprises at least two foam concrete layers, wherein at least one reinforcement layer is situated in between two foam concrete layers.
