Dear Marcus,

Why should concrete be mixed with fly ash? Because fly ash is used as a blending agent for concrete, it is mainly used to improve concrete performance; and the microstructure of fly ash is spherical particles, finer than cement, it also has a certain activity, it can replace part of the cement when mixed into cement, and can increase the fluidity of the concrete mixture, greatly improve the pumpability of the pumped concrete, and also improve the late strength and durability of the concrete.
 
How to prepare fly ash? The main source of fly ash is the ash collection of coal-fired power plants and urban central heating boilers.
