This TechNote discusses the impliions of limits on the proportions of fly ash in project specifiions. This TechNote addresses only fly ash that meets current, applicable specifiions such as ASTM C618. Prescriptive specifiions for concrete construction projects often include a clause that limits the proportion of supple mentary cementitious materials (SCMs) (Obla and .
Features of Fly Ash. Fly ash is fine ash collected from coalfired flue gas. It is the main solid waste discharged from coalfired power plants. Fly ash is a complex mixture of crystals, glass and a small amount of unburned carbon. Fly ash is gray in the dry state, with little or no hydraulic gelling, fly ash with large water content is grayish ...
· To study the durability of concrete with fly ash as fine aggregate subjected to alternative attacks of freezethaw and carbonation, the appearance, mass loss, relative dynamic modulus of elasticity, relative compressive strength, and carbonation depth of the concrete are investigated using cyclic tests under single carbonation, single freezethaw, and alternation of .
· Fly ashes from municipal solid waste incineration contain significant amounts of (technology critical) elements. Processes to recover Cu or Zn are already in practice, but it still remains difficult to evaluate the full secondary resource potential of the ashes. One reason is the absence of a worldwide comparable analytical basis for detailed market analyses.

· Coal power plants worldwide produce a huge amount of waste fly ash, which not only causes environmental problems but is a threat to human health [1, 2]. China is the largest producer of fly ash globally, and it produced approximately 600 million tons of fly ash in 2016. By the end of 2016, the waste fly ash has piled up to three billion tons.
· The use of industrial waste as a potential stabilizer of marginal construction materials is cost effective. Phosphogypsum and fly ash are industrial wastes generated in very large quantities and readily available in South Africa. In order to explore the potential stabilization of vastly abundant expansive soil using larger quantity phosphogypsum waste as a potential .
The compressive strength, free and restrained drying shrinkage and cracking resistance of concrete under drying condition were investigated for ternary cementitious systems containing Portland cement, slag and fly ash. The restrained shrinkage test (ring test) was carried out following ASTM C1581. The results showed that the increased replacement level of slag or fly .
