ELECTRIC  PULSE  TECHNOLOGY  FOR  AGGREGATE  AND  AGGREGATE-BASED  CONCRETE  PRODUCTION

In this paper, some aspects of electric pulse technology used for crushing aggregates and their properties are shown. The paper presents technical facilities and instrumentation of the processing line main units of electric pulse technology. Experimental data are given for concrete properties based on activated aggregates. The quality of aggregates obtained using this technology and controlled both by discharge channel energy and its yield time was improved. The properties of the contact area between the activated aggregate surface of pore formation and cement matrix were studied. Aggregate concretes obtained by the electric pulse technology meet the requirements for high-strength concretes having the improved values of cement content vs unit strength and weight strength vs unit cement content.

Key words: electric pulse technology; aggregate; cement; cement concrete; contact area; processing line.
