METHOD OF MANUFACTURING NON-PRESSURE ESPECIALLY LIGHT CONCRETE WITH CEMENT BINDER Russian patent published in 1999 - IPC

Abstract RU 2132835 C1

FIELD: manufacture of building materials. SUBSTANCE: method consists in stirring binder with polystyrene foam, cement-polystyrene paste being mixed with process foam in high-speed foam-concrete mixer. In the course of mixing, electric power plant ashes and lump lime are added to mixture to achieve following contents of components, wt %: cement 25- 60, process foam 7-15, polystyrene foam 0.5-1.5, ashes 20-30, lump lime 5- 10, and tempering water - the balance. Process foam is prepared in gerotor-type foam generator with rotation speed of gerotor couple 1000- 1200 rpm. EFFECT: reduced production expenses and combustibility of building material. 2 cl, 1
