Plastic and stone, the by the solidification is produced from the sand, composition for the consolidation of the sand and a method for the consolidation of the sand

摘要

The object of the invention is a by the solidification is produced from the sand plastic and stone, characterized in that the following constituents: 65 – 80 w -% sand, 5 – 15 w -% of water glass, water glass hardener in 5 – 10 w -% based on the water glass, 3 – 10 w -% sulfur polymer, 3 – 8 w -% nano - and / or micro - silica, wherein the plastic and stone has a density of 1,65 – 1,85 kg / dm³, the water absorption capacity of & 6,4%, the wear of 0,1 – 0,4 cm, the frost resistance of 44 cycles and the fire resistance of & 1150°C. The subject matter of the invention are also the composition for the consolidation of the sand and the process for the solidification from the sand.
