Production of modifying additives for highways

Abstract

Abstract The article presents a description and operating parameters of the technological process for the production of modifying additives for concrete and asphalt concrete based on exhaust gas dust in the production of silicon by operations. Described is a foam product, which is a raw material for obtaining fullerene-like carbon, a modifying additive MD2, and a chamber product for spherical silicon dioxide, a modifying additive MD1. The regulated parameters have been worked out, the regulation limits and the norms of expenses are given. The development of a functional diagram is based on the analysis of the technological process, as an object of automation, in which the main control and controlled influences are distinguished, which must be regulated and maintained within specified limits, in order to obtain the final product with the required quality characteristics. The implementation of this scheme is presented in this work. It combines a flow diagram and technical means measuring, controlling and regulating these flows, in order to ultimately obtain products of the desired quality.
