Any hydraulic cementitious material made of Portland cement clinker, 20-40% fly ash and appropriate amount of gypsum, called fly ash Portland cement, referred to as fly ash cement, code P ·F.
According to the Chinese standard, the amount of fly ash in cement is 20-40% by weight; it is allowed to add granulated blast furnace slag not exceeding 1/3 of the total blending amount of mixed materials. At this time, the total blending amount of the mixed materials can reach 50%. %, but the amount of fly ash is still not less than 20% or more than 40%.
Fly ash cement is divided into five labels of 275, 325, 425, 525 and 625. In addition to the characteristics of volcanic gray Portland cement (such as low early strength, but the late strength enhancement rate, low hydration heat, etc.), it also has less water demand and shrinkage, and workability, Good resistance to cracking and sulfate attack. Suitable for large-scale hydraulic construction, but also for general industrial and civil construction. Since the 1960s, France, Japan, the Soviet Union, China, the United States, and the Federal Republic of Germany have successively produced fly ash cement, and the output has increased. China began to study fly ash as a cement mixed material in the early 1950s, and in 1977 formulated a standard for fly ash Portland cement.
