COMPOSITION FOR FABRICATING STRUCTURAL ELEMENTS Russian patent published in 1998 - IPC

FIELD: manufacture of building materials. SUBSTANCE: invention more specifically relates to fabricating various small-size structural elements from liquid- glass compositions. Objective is achieved by that original structural composition contains multifunctional filler also functioning as hardening initiator. Filler constitutes a high-dispersity powder with specific surface 10000-11000 sq.cm/g formed upon neutralization of waste water from superphosphate production. When mixed with liquid glass, soluble glass binder is hardened by way of being transformed into disperse system with solid phase exhibiting binding properties when being isolated. EFFECT: reduced cost thanks to avoided use of expensive sodium silica-fluoride as filler. 2 tbl
