Abstract

The invention provides high-performance cement with high-content yellow phosphorus slag and a production process of the high-performance cement, and relates to the technical field of cement, the high-performance cement is prepared from the following raw materials in parts by weight: 100 parts of Portland cement clinker, 5-15 parts of gypsum, 60-110 parts of yellow phosphorus slag powder, 10-35 parts of nickel slag powder, 10-18 parts of zeolite powder, 6-11 parts of rectorite powder, 2-6 parts of hydrotalcite powder, 0.3-1.2 parts of cane sugar and 0.6-1.3 parts of alkali metal hydroxide. According to the invention, the stacking problem of the yellow phosphorus slag and the nickel slag is further solved, the additional value of the waste slag is improved, and the prepared cement product ishigh in strength and good in construction performance by matching with the zeolite powder, rectorite powder, hydrotalcite powder, sucrose, alkali metal hydroxide and the like.

Description

technical field [0001] The invention relates to the technical field of cement, in particular to a high-performance cement with a large amount of yellow phosphorus slag and a production process thereof. Background technique [0002] Cement has many advantages that other materials do not have. Cement is not like ordinary plastics that are prone to aging after a long time of use, and unlike steel that is easy to rust after a long time. Therefore, it is a widely used building material. Whether its production technology and equipment are advanced or not, and the level of production capacity all affect the rise and fall of the entire construction industry. With the development of society, people pay more and more attention to environmental protection and waste recycling. At present, in the field of cement, the use of industrial waste as a raw material for cement production has been well developed. It can slow down the excessive consumption of non-renewable resources such as clay ...
