A CONCRETE MIXTURE FOR FILLING

摘要

A concrete mixture for filling linings of heat units of high slag resistant and a high degree of adhesion contains, % by weight: 47-59 of electrocorundum; 18-20 of finely dispersed alumomagnesial spinel of the fraction less than 0.5 mm; 10-14 of mixture of ultradisperse aluminas with specific surface area of 4.4-5.0 m2/g and 15.5-16.5 m2/g at a ratio of 1-3:0.5-1.5; 9-11 of high alumina cement; 3.88-7.86 of non metallurgical mille alumina with the content of particles, less than 4 mum not leas than 40 %; 0.07-0.13 of organic propylene fiber with fibers length of 4-8 mm, 0.01-0.05 of water-soluble methyl celluloses.
