Problems solved by technology

[0002] The traditional cement-based mortar preparation is generally made by mixing cement, sand and water manually or with a mortar mixer. The general sand ratio is 1 to 3, that is, 1 kg of cement is mixed with 3 kg of sand; Other auxiliary materials must be added, such as lime powder, finely ground fly ash, lime paste, mortar admixture, etc. to solve the consistency problem of the mortar, which is not only troublesome to use, but also difficult to accurately grasp the amount of auxiliary materials added. It affects the quality of the mortar, makes it difficult to guarantee the quality of the project, and directly affects the quality of the building.
