FIELD: construction. ^ SUBSTANCE: raw mix for light-weight concrete production contains, wt %: cement 61.50-62.30, foam polystyrene 5.8, neutralised air-entraining resin SDO 0.15, nickel containing sludge 3.0 - 5.0, the rest is water. Raw mix is produced by mixing foam polystyrene granules, water and nickel containing sludge. While mixing cement and the solution of the aforesaid resin are introduced. ^ EFFECT: improved strength of polystyrene concrete, decreased average density and improved operational characteristics of structures and items made of polystyrene concrete. ^ 3 ex, 1 tbl |
