Title: Energy and valuable material by-product from firing Estonian oil shale

Abstract

Power plants of Eesti Energia burn Estonian oil shale, known geologically as kukersite, to produce electrical and heat energy. The burnt shale, or oil shale ash, secondary product is collected and stored in increasing quantities. It is a high calcium content material with a low particle size range. Limited investment and international support have minimized development; however, some possibilities for the use of the ash have been found with consequent improvement to the environment. This paper describes different ways in which this burnt ash may be used. In particular, research has shown that it is most effective as an addition to Portland cement production. An Estonian Standard for the use of burnt shale in the production of rapid hardening portland cement and shale Portland cement has been developed. Characteristic data for burnt shale and burnt shale cellular concrete, collation of shale Portland cement and ordinary Portland cements are given.
