METHOD OF PREPARING POLYSTYRENE CONCRETE MIX Russian patent published in 1997 - IPC

Abstract RU 2090532 C1

FIELD: manufacture of building materials, particularly, light-weight concrete polystyrene filled mixes. SUBSTANCE: method for preparing polystyrene concrete mix comprises stirring granular polystyrene with organic additive, mixture of saponified wood resin and caprolactam waste from aqueous benzene layer based on mono- and dicarboxylic acids in 30-60 and 40-70 ratio and subsequently mixing with cement and water, the ratio of components is as follows, wt.-%: cement, 67-62; granular polystyrene, 5-6.5; organic additive, 0.15-0.35; and water, the balance. Composition strength of concrete after 28 days is 127 kgf/sq.cm. bending strength is 4.8 kgf/sq.cm. heat conduction is 0.103 W/m.K. EFFECT: more efficient preparation method. 3 cl, 2 tbl
