FIELD: chemistry.
SUBSTANCE: invention relates to production of building materials and specifically large size thin-wall panels. The fibre-reinforced cement mixture contains portland cement, quartz sand, cellulose fibre, kaolin, polyacrylamide, polyphenyl ethoxysiloxane and water, with the following ratio of components, wt % per dry substance: portland cement - 19-23, quartz sand - 63.9992-68.99995, cellulose fibre - 5-6%, kaolin - 6-7, polyacrylamide - 0.00005-0.0001, polyphenyl ethoxysiloxane - 0.0007-0.0008, wherein the degree of grinding of the quartz sand is 210-310 m2/kg, the degree of grinding of cellulose fibre is 30-35°SR and the degree of grinding of kaolin is 1300-1400 m2/kg.
EFFECT: high bending strength of the finished product while reducing consumption of portland cement.
