Abstract

This article presents the results of experimental research of the chemical composition, structural features and operational characteristics of ash and slag waste and waste from crushed stone production (Trans-Baikal region) for the purpose of their utilization in road soil concrete compositions. It was revealed that locomotive slag belongs to the category of non-porous. It was revealed that the studied fly ash in terms of hydraulic properties are classified as latent-active. It is shown that the investigated samples of screenings and fly ash belong to the 1st class of materials according to the radiation characteristic, since the value of the specific effective activity of natural radionuclides (Aeff) has a value of no more than 370 Bq/kg and the studied mineral raw materials can be used in the construction industry without restrictions. It was experimentally established that the optimal dosage of the mineral binder and fly ash in soil concrete samples was 8 and 10 wt. %, respectively. Introduction 1 wt. % of the stabilizer makes it possible to obtain frost-resistant samples with a strength grade of M 40.
