Problems solved by technology
[0002] According to research, there are many ways to produce mortar ash by using fly ash at present. Pure fly ash mortar ash is obtained by adding quicklime, quick gypsum and crystal billet to the coal ash and grinding together. Although this method has achieved good economic results, it still has high energy consumption and high cost, and the dehydration of the mortar ash is fast and easy Deficiencies such as shrinkage and cracking

Embodiment Construction
[0006] The specific embodiments of the present invention will be described in detail below in combination with the list.
[0007]
[0008] Add boron mud, phosphogypsum, aluminum sulfate and sodium metaaluminate to high-calcium fly ash and low-calcium fly ash according to the weight percentage required in the above list and grind to the required fineness. The mortar ash obtained in this specific example has been used in the office of Liaohua Energy Conservation Center, the residential buildings of Liaohua District 18 and 20, and the component factory of Chaoyang No. 2 Construction Company. Both parties A and B are very satisfied and have achieved considerable economic benefits. and social benefits.

The invention relates to a method for producing mortar ash by using high-dopant fly ash, boron mud, little ardealite and excitant. The produced mortar ash can completely replace lime, can replace 20% of five species of cement, and can be widely used for masonry, inner wall plasterer, highway subgrade and production of hollow bricks and floor tiles and the like. In the invention, the process is simple, cement clinker and crystal slab are not added during the course of processing, the dopant amounts of the boron mud and fly ash are up to 80%; and the investment is less, and the cost is low, the grade I and II mortar ashes produced by the method do not contain chloridions, and the properties (such as peaceability, microexpansibility, dehydration, strength and the like) of the grade I and II mortar ashes are far higher than those of the existing fly ash and mortar ash as well as calcined lime powder for construction.
Description
1. Technical field: [0001] The invention relates to a method for producing mortar ash mainly by using industrial waste, especially high-volume fly ash and boron mud and a small amount of phosphogypsum and activator. The products produced by the method can replace lime 100% and 20% Five types of cement are widely used in masonry, interior wall plastering, road subgrade and production of hollow bricks and floor bricks. 2. Background technology: [0002] According to research, there are many ways to produce mortar ash by using fly ash at present. Pure fly ash mortar ash is obtained by adding quicklime, quick gypsum and crystal billet to the coal ash and grinding together. Although this method has achieved good economic results, it still has high energy consumption and high cost, and the dehydration of the mortar ash is fast and easy Shrinkage, cracking and other deficiencies. 3. Contents of the invention: [0003] In order to overcome the above-mentioned defects of the prio...
