DEFLOCCULATION OF HIGH ALUMINA MATRIX SYSTEMS WITH POLYCARBOXYLATE ETHER ADDITIVES

A comparative analysis of the effectiveness deflocculating effect Russian and international polycarboxylate ethers additives on rheological properties high-alumina matrix suspensions is presented in this article. For production functional systems, submicron activated α-alumina modified high alumina cement are used ratio 80:20 90:10 wt. %, respec-tively. fluidity with a moisture content 20% carried out to assess pres-ence different deflocculants concentrations. All grades manifested by rather effects identifying suspensions. The best recorded for suspen-sions deflocculated Cinteflow DUO 60 (0.38 %). large influence expiration time noted. Probability thickening within 30 min. illumination largely determined type introduced deflocculants. spreadability has been studied. certain casting mixtures 12 maximum diluting using Sinteflow DM 50 (0.34 Deflocculants based polycar-boxylate produced Sintez OKA Group Companies (Russia) show impressive efficiency compared complex deflocculant Peramin AL 200 300 (Kerneos, France).
