METHOD OF PRODUCTION OF DRY BUILDING MIX

摘要

FIELD: construction engineering; production of dry building mixes for protection of structures against aggressive external factors. ^ SUBSTANCE: proposed method includes grinding of expanded-clay lightweight concrete whose service life has expired or off-grade expanded-clay lightweight concrete together with natural witherite in presence of plasticizing additive. Proposed method excludes sulfate and biological corrosion and makes it possible to use expanded-clay lightweight concrete whose service life has expired or off-grade expanded-clay lightweight concrete. ^ EFFECT: enhanced waterproofness of structures at high humidity; utilization of technogenic waste. ^ 1 ex
