Nephrite-Bearing Mining Waste As a Promising Mineral Additive in the Production of New Cement Types

摘要: A growing demand for products made of jewelry and ornamental stones, including nephrite, requires an increase in mining volume. However, only less than 30% the extracted raw material is suitable processing. The rest low grade nephrites are substandard unclaimed, they negatively affect various life spheres. In this regard, their involvement industrial turnover actual task. One directions waste use production building materials, particular, cements. nephrite can act here as mineral additives. course research, optimal amount additive was determined, which cement mass. grinding time a mix 10 min. It found that introduction affects hydration activity compositions. Compressive strength mixed 25% higher control sample. At same time, new phases hydrated were not recorded. Good physical mechanical properties obtained cements achieved when hardening normal humidity conditions. Heat treatments do facilitate processes binary systems. conducted studies have shown be used additives production. This will allow development type product, but also reduction negative impact on environment.
