Fly ash can be a costeffective substitute for Portland cement in many markets. Fly ash is also recognized as an environmentally friendly material because it is a byproduct and has low embodied energy, the measure of how much energy is consumed in producing and shipping a building contrast, Portland cement has a very high embodied energy because its production requires a great .
Global cement production is expected to increase from billion metric tons in 2010 to billion metric tons in 2030. In China, the cement production in 2015 amounted to some million tons.
Called admixtures, these additives can be used to increase the workability of a cement mixture still in the nonset state, the strength of cement after application, and the material''s water tightness. Further, they can decrease the amount of water necessary to obtain workability and the amount of cement needed to create strong concrete.
Strategies for Improving Sustainability of Concrete Pavements . 3 • For a selected lifecycle time period, what is the total lifecycle impact resulting from using a paving material only once versus using it multiple times? • If a recycled, coproduct, or waste material (RCWM) is considered for use in a pavement construction project,
