Economic evaluation of using of geopolymer from coal fly ash in the industry

Popis výsledku v původním jazyce

At the present time, almost every area needs using of secondary raw material sources. This trend is most obvious in the industry, mainly in the area of materials production, when there is a possibility of economic effectiveness increasing during production. Also, the contribution of secondary raw material using is not negligible in the area of living environment protection, since it can use the waste of industrial production again. The task of this contribution is an economic evaluation of using a geopolymer from coal combustion as a possible alternative raw material. The basic input is the cost of materials for the manufacture of concrete using of Portland cement with fly ash as a substitute for cement and fly ash as an additive to concrete. Evaluation is carried out based on analysis of the possibilities to reduce the total price of material costs for the production of 1 m(3) of concrete, with possible using in the industry. The main method for economic evaluation of using geopolymer is the classical cost calculation. The results of the analysis show possible reducing of cost, which is possible through replacement of cement by fly ash more than 18 % of the material.
