Abstract
The article suggests recycling aluminium and pipe industry wastes in the production of refractory materials. New compositions of light fibrous concrete are developed, compared to the known structures they have improved physical and mechanical properties and a low cost. This is achieved due to the lack of heat treatment and utilization of industrial waste. Aluminous slag and sulphate sludge are stored in open landfills. Recycling of slag and sludge helps to improve the ecological state of environment. This article describes the chemical composition of the waste and suggests the optimal ratio of the mixture components. The properties of refractory fibrous concretes were defined at hardening of mixture in the natural conditions in the absence of heat treatment.
