The concrete-based high performance decorative material for severe climatic conditions

摘要

This paper presents experimental investigations on the development of high performance colored concrete-based decorative materials for regions with severe climatic conditions. The main idea of the research is the creation of concrete-based material with admixtures, consisting of mechanically activated crushed concrete fines. In this context, the influence of mechanic-chemical activation of admixture and coarse aggregate to the properties of decorative concrete were examined. Firstly, main features of the severe environment, which affects the decorative exterior materials, and methods of protection against them are shown. The optimized concrete mixes and their main properties are presented based on analysis of these features. The main areas of the usage of designed concrete-based materials are specified in the Siberian and Far East regions of Russian Federation.
