Nghiên cứu đánh giá chất lượng tro bay, xỉ lò cao của các nhà máy nhiệt điện và luyện kim ở Việt Nam

Abstract

The article present studies evaluating the quality of fly ash and blast furnace slag are wastes of Thermal and Metallurgical plants in Vietnam. Fly ash and blast furnace slag are the two materials used to make activated alkali binder without using cement binders. The potential for using fly ash and blast furnace slag from thermal and metallurgical plants in Vietnam as an activated alkali binder for geopolymers concrete is enormous. It contributes to reducing the environmental pollution caused by these wastes, on the other hand also brings many economic and technical efficiency because geopolymer concrete has many outstanding features compared to conventional concrete, it show the ability for corrosive resistance in  corrosive environments such as brackish water and seawater, so it is very suitable for coastal and island constructions.
