Abstract

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.

Highlights

The development of Russia's northern and eastern regions, which are characterized by severe climatic conditions, according to the Government order of July 5, 2010
The usage of decorative materials is based on proven technologies, developed in 1950-80’s [5,6,7].Besides low capillary porosity, Corresponding author: pilipenko.ans@gmail.com decorative materials should meet the specific requirements on the quality of the front surface of the windshield and to ensure the absence of snow accumulation on the surface of buildings
Developed concrete can better resist the effects of the severe climatic conditions

Summary

Introduction

The development of Russia's northern and eastern regions, which are characterized by severe climatic conditions, according to the Government order of July 5, 2010 No 1120-r "The Strategy of socio-economic development of Siberia 2020", due to the construction of new and reconstruction of the old transport network, energy network, information and telecommunication infrastructure of Siberia, residential and industrial projects. Traditional materials based on cement binder could not always meet these requirements, but their main disadvantage is the relatively low durability. Depending on the method of grinding, the concrete waste may have different properties which make it optimal for use in certain materials [8] All of these types of industry waste have been studied for possibility of their usage in decorative concrete previously [9]. The creation of high-performance concrete-based decorative materials for regions with severe climatic conditions could be economically attractive This could be achieved by development of high-performance concrete with high compressive strength (60-120 MPa and above), frost resistance (more than the F400), water-resistance (more than the W12),low abrasion (less than 0.4 g/cm2), and high bleaching resistance
