ABSTRACT:
A solid fixation product of harmful, water-containing waste materials and cement, which product is highly resistant to leaching by water and salt solutions. The product has a high content of 20 to 50% of waste materials based on the dry weight of the waste in the product and a water content corresponding to a water-to-cement ratio of 0.2 to 0.45. The method according to the invention which permits producing of such products is characterized in that evaporation of the water-containing waste materials and the mixing with the fixation matrix takes place concurrently at temperatures of 100.degree. to 180.degree. C. The resulting solid fixation product is of relatively small volume and, accordingly, requires only relatively little storage space.
