Use of the Electric Steel Melting Slag in Production of the Expanded Clay Gravel

Abstract:

The paper shows the possibility of production of the expanded clay aggregate with the use of electric steel melting slag up to 3.0 % produced by JSC “Oskol Electric Steel Works”. It was determined that at the temperature of 1170 °C the expanded clay aggregate with high strength properties and a high coefficient of swelling is formed. The preliminary thermal preparation of the samples with slag addition was at 500 oC. An opportunity to use iron-containing waste was revealed which lowers the temperature of the expanded clay aggregate burning. By means of the X-ray phase analysis the mineral mullite Al₅SiO_9.5 was found in the resulted samples of the expanded clay aggregate with an optimal addition of slag which reinforces a glass phase of granules and strengthens it. The results can be used for production of the expanded clay gravel with the use of industrial wastes. The technological scheme of the expanded clay production with the use of waste can be carried out without making any additional capital investments.
