The difference is: the fly ash brick is made of various fly ash industrial waste materials by fly ash brick machine, and the use of fly ash comprehensive utilization technology is adjusted and processed. The concrete block can be considered as a wider range. Fly ash is used as concrete Fly ash is added to block auxiliary materials, and the ratio and composition are somewhat different. The manufacturing process is different.
Fly ash looks like cement, but varies from milky white to gray-black due to combustion conditions and color. The color of fly ash is an important quality indicator, it can not only reflect the amount and difference of carbon content. And to a certain extent, it can also reflect the fineness of fly ash. The darker the color, the finer the particle size of fly ash and the higher the carbon content. Fly ash is divided into low-calcium fly ash and high-calcium fly ash. Usually, the color of high-calcium fly ash is yellowish, and the color of low-calcium fly ash is grayish.
Concrete, abbreviated as "concrete (tóng)": refers to a collective term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete that uses cement as cementing material and sand and stone as aggregate; it is mixed with water (which may contain admixtures and admixtures) in a certain proportion and is mixed with cement concrete, also called ordinary Concrete, it is widely used in civil engineering.
