the deck concrete consisted of cement (75%), fly ash (17%), and silica fume (8%). The girders were fabricated with a concrete containing silica fume and having a water-cementitious materials ratio of 0.25. Several trial batches and test placements were performed by the fabricator to obtain the desired early strength and workability.…

test, respectively. The sludge ash/cement paste specimens were produced with a water/cement ratio of 0.5. The cement was replaced with four different amounts of in-cinerated sewage sludge ash: 0, 10, 20, or 30% (by weight). The samples were amended with 0 or 2% of three different types of nano-SiO 2 additives: SS, HS, and SP. The mortar…

A set of data from the British Geological Society of 11 coal ash samples showed that even the lowest level of scandium seen in these samples was worth nearly US 5000 per tonne of fly ash, with the more enriched ashes reaching over US 40,000 per tonne of fly ash, and the maximum germanium levels at almost US 3500.…

mixture) the stiffness of the granite mastic is double that of fly ash mastic. This demonstrates the potential extended range of use of fly ash in HMA beyond that of traditional mineral filler. The mastic integrity is tested at the same concentrations shown in Figure 2 that also illustrates mastics performance with fly ash and granite.…

Fly ash Wikipedia. Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coalfired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called .…

This paper deals with the effect of mineral admixtures and Geopolymer on preventing excessive expansion due to alkali-silica reaction (ASR). The test method used was ASTM C 441-97. Expansions of mortar-bars were measured at 14, 56, 90 days. The results prove that mineral admixtures can effectively restrain ASR. When three kinds of mineral admixtures, silica fume, fly ash, and ground granulated .…
