Physico-mechanical properties of foam concrete with a keratin-based foaming agent

Abstract

The work shows that the technology for producing keratin-based foaming agent, in terms of its physicochemical characteristics, is highly competitive with other foam concrete with another foaming agent. The study describes the compositions of foam concrete on the basis of a keratin-based foaming agent and its basic physicomechanical properties. The effect of the keratin-based foaming agent in terms of increasing the timing of the beginning and end of the cement setting in cement systems is less than in traditional foam concrete. This is explained by the presence of the complex additive MB-01 and Aquatron-6, which seal the Plato channels and contribute to retaining more water in the foaming agent films. A complex of technological methods for the use of keratin raw materials and calcium hydroxide for its hydrolysis, as well as the mineral-chemical additives MB-01 and Aquatron-6, made it possible to produce foam concrete with given properties of strength and density.
