Improper treatment can lead to substantial potential safety hazards. In this research, a high-temperature treatment was applied to degrade the dioxin in waste fly ash which was reduced to 1/1209 of the untreated level. Then, based on an Andreasen and Andersen model, the waste fly ash was used to prepare ultra-high-performance concrete (UHPC).
The paper presents experimental studies on the influence of a simultaneous, appropriately proportioned combination of microsilica and fly ash additives on the physical and mechanical properties of ultra-high-performance concretes (UHPCs). Concrete mixtures with the addition of microsilica in the amount of 6.7–14.7% and fly ash in the amount of 8.3–26.7% …

This study developed ultra-high performance fly ash composite (UHPFC) by enhancing the pozzolanic reactivity of low-calcium fly ash (FA). Although it did not include Portland cement, the composite exhibited outstanding performance in workability, mechanical properties, and strength development. At room temperature (20 °C), the hydrated lime …

espanolEl concreto de ultra alto desempeno (UHPC) es un tipo de concreto de alta tecnologia con excelentes propiedades mecanicas y de durabilidad en comparacion con otros tipos de concreto. Sin embargo, debido al alto contenido de cemento y micro silice necesarios, el costo y el impacto ambiental de UHPC es considerablemente mayor que el del concreto convencional. Por esta …
In this paper, the flowability, compressive strength, hydration heat, porosity and calcium hydroxide content of cement-silica fume-fly ash-based ultra-high-strength concrete (UHSC) incorporating ...
From these investigations, the ultra-fine treatment is expected to significantly improve the pozzolanic reactivity of fly ash, enabling the wider application of high-volume fly …
Fly ash (FA) is a by-product from furnaces fired with pulverized coal, often power-plants. It consists of spherical particles as shown in Fig. 2c. Fly ash can be either an aluminosilicate or a calcium silicate, and because of the reactive silicon dioxide (SiO 2) that both types contain, fly ash has pozzolanic properties [18, 19].
This paper discusses the fresh and hardened properties of concrete made with an ultra-fine fly ash (UFFA) produced by air classification. Durability testing for chloride diffusivity, rapid ...
Although a large amount of low-calcium fly ash (FA) is produced annually (about 900–1000 million tons), its utilization is considerably low at ∼30% [1, 2].This rate contrasts starkly with other industrial byproduct-based supplementary cementitious materials (SCMs), such as ground granulated blast furnace slag (GGBFS) and silica fume; these SCMs have been …
