Potential of building materials from coal ash - recycling solution for environmental protection and economic efficiency

Abstract

This paper mentions some solutions to reuse ash and slag of Vung Ang thermal power plant. Whithin the possible solutions, the use of coal ash as a construction material is a potential solution, bringing high economic efficiency to thoroughly solve environmental problems and in the long run. The results of the study generally evaluate the use of these waste products, which are very satisfactory, highly practical and beneficial in many aspects. The reality shows that feasible options in terms of technology, technology and capacity scale in Vietnam the amount of fly ash and bottom slag used in the construction industry: 29%
concrete admixture, 37% construction road, 5% fillers, 15% fly ash cement, 45% concrete blocks, raw materials for cement production 27%, 1% - 2% other applications
