MODIFICATION OF FINE-GRAINED CONCRETE ADDITIVES CRUSHED PLASTIC

Abstract

Over the past 150 years, artificial marble has been used, which can have a variety of colors and textures, and also has the ability to easily take the required shape in the manufacture of parts of any complexity. There are many ways to obtain artificial marble and formulations of mixtures, most of which include cement as a binder and quartz sand as an aggregate. This paper shows that ground glass waste can be a substitute for quartz sand or a part of it in the preparation of mixtures for producing artificial marble, which leads to an increase in the strength of the material in compression and a decrease in its water absorption. Black iron oxide pigment, light ocher, redoxide have been approved as coloring additives in the production of artificial marble. It is proposed to unevenly distribute these additives in mixtures with the inclusion of ground glass waste, which makes it possible to achieve an approximate similarity in the appearance of the resulting material with natural marble.
