UGNIAI ATSPARAUS BETONO KOMPOZICIJA

摘要

The invention relates to building industry, especially to refractory concrete compositions, particularly to refractory concrete compositions with a catalyst waste supplement. Objective of the invention is to improve physical and operating characteristics. The refractory concrete composition contains binder with a catalyst waste, chamotte filler and ground chamotte; the binder is alumina chamotte and composition additionaly includes silica fume, reactive aluminium oxide, polycarboxylate ester with the ratio of components, in mass percent:@alumina cement 8-12@silica fume 2-10@reactive aluminium oxide 3-6@catalyst waste supplement 2-20@ground chamotte 5-20@chamotte filler 50-65@polycarboxylate ester 0,1-0,35@inhibitor 0,05-0,15@water residual amount.@
