The present invention relates to a process for the manufacture of articles made of conglomerate material, more particularly in the form of slabs or blocks, starting from a mixture comprising an optionally expanded granulate of stone material or lithoid material, and a binder based on a resin obtained from acrylate vegetal oils. The present invention also relates to the articles thus obtained.

Prefabricated floor element (1) having an elongated shape wherein a longitudinal direction (X), a transversal direction (Y), a height direction (Z), two end faces (11) which delimitate the element (1) in the longitudinal direction (X), two lateral faces (12) which delimitate the element (1) in the transversal direction (Y), a lower face (13) and an upper planar face (14) that delimitate the element (1) in the height direction (Z) are defined, which comprises transversal continuous upper grooves (15) on the upper planar face (14) or lateral grooves (26) on the lateral faces (24), the lateral grooves (26) extending from the lower tab (TS) to the upper planar face (24). The invention also relates to a structure comprising such prefabricated floor element (1) and further comprising a linear supporting element (LS) which supports one end of the prefabricated floor element.

Disclosed is a measurement device for a vibration device of a concrete-block production plant. The vibration device has a vibrating table and impact strips arranged parallel to each other and parallel to the ground with relation to their longitudinal axes. The measurement device comprises at least one measurement unit for distance. The measurement unit is arranged above the vibrating table and the impact strips, wherein the measurement unit can be guided orthogonally to the impact strips and parallel to the ground using a guide unit. During the guiding process, the measurement unit operates at predefined measuring positions and/or positions determined during the guiding process via the impact strips and the vibrating table, using the measurement unit, the vertical distances from the top sides of the impact strips and/or the vibrating table to reference positions, which result from the heights of the measurement unit at the respective measuring positions, can be determined.

A cement-based artificial stone plate includes a cement-based plate body; and a metal mesh being embedded in the cement-based plate body; wherein the metal mesh is arranged with at least one fixing member, the fixing member defines a screw hole along its axis, and the screw hole of the fixing member is exposed on back of the cement-based plate body, and back of the plate body is provided with regular or irregular protrusions, between any two protrusions forms a groove, and bottom of each groove is close to the metal mesh.
