Powder and fine sand portions, accelerator and resin are mixed in one premixer and gravel, hardener and resin are mixed in a second premixer. The separate mixtures are brought together from the buffer (15) after the first and second premixers (14, 22) to a continuous mixer (25) to give a concrete mass for molding (31). To produce molded reaction resin concrete, a number of additives of different particle size namely a powder, fine sand and gravel are mixed with liquid resin and reaction agents namely hardener and accelerator. The powder and fine sand portions and at least part of the accelerator are prepared, on one side, and the gravel and at least part of the hardener are prepared on the other side. They are prepared separately in premixers (14, 22), each with a part of the resin component. The separate mixtures are brought together from the buffer (15) after the first premixer (14) and the second premixer (22) to a continuous mixer (25) to give a concrete mass for molding (31).
