COMPOSITE LIME-SILICEOUS BINDER FOR AUTOCLAVE-HARDENED SILICATE PRODUCTS

摘要

FIELD: binding materials.;SUBSTANCE: invention relates to the technology of binding materials, it can be used in the manufacture of silicate pressed products. The composite lime-siliceous binder is prepared by joint grinding of 50 wt.% quicklime, 10-25 wt.% of quartz sand and additives. At the same time, as additives, the binder contains 15-30 wt.% of the carbonate rock of class A or B and 5-10 wt.% of the crushed stone from silicate pressed products of autoclave hardening. The grinding is carried out to a specific surface area of 400 m2/g. ;EFFECT: expansion of the raw material base, reducing the consumption of sand, increasing the raw and autoclave strength of products.;1 cl, 3 tbl, 1 dwg
