Efficient Ceramics Based on Organic Waste of the Republic of Khakassia

The problem of accumulation of production and consumption waste is one of the most acute environmental problems of today. In Russia, a large amount of waste is generated annually, which is often stored or buried instead of being involved in an economic turnover. One of the promising areas for using industrial waste is the production of building materials. Purpose : The study of complex burnout additives to improve construction and technical properties of effective ceramic bricks. Methodology : Clay, wood sawdust, technical hydrolysis lignin, fly ash are used in experi-ments. The samples are produced by semi-dry pressing. Physical and mechanical properties of products are determined according to standard methods. Research findings : Determination of the effect of additives on the properties of ceramic bricks. The average density, thermal conductivity and fire shrinkage of the obtained ceramic products are determined. Research findings confirm the prospects of using a complex additive of lignin with sawdust for the production of effective ceramics. In this case, the additive content should not exceed 20 % of the total ceramic mass.
