METHOD FOR PREPARING GAS-GENERATING AGENT USED TO MAKE POROUS CELLULAR CONCRETE MIXES Russian patent published in 1997 - IPC

Abstract RU 2081860 C1

FIELD: production of building materials. SUBSTANCE: present invention recommends to use polyethylene oxide for preparing gas-generating agent by grinding aluminium-based dispersed alloy. Polyethylene oxide with molecular weight (1.6-4.0)(1,6-4,0)10⁶ is used. Grinding is terminated as soon as polyethylene oxide reaches molecular weight (4.1-6.0)(4,1-6,0)10⁶, amount of polyethylene oxide accounting for 1-5% by weight of dispersed alloy weight. EFFECT: proposed is highly active gas-liberating agent useful in producing fast hardening concretes. 2 tbl
