The use of green materials In the past, we did not emphasize the saving of materials in the architectural design, this led to the waste of raw materials during the city construction.
In the late 1990s, the green building materials has been developed rapidly.
In foreign countries, performance criterion for different kinds of green building materials has been established and the environmental mark has been introduced to regulate the development of green building materials.
China has successively promulgated some standards related to air quality and green building materials, such as " Indoor decorating and refurbishing materials--Limit of harmful substances of interior architectural coatings " etc.

Introduction Ferrites are widely used as synthetic materials and minerals in different fields for a long time.
Ferrites are metallic oxide materials.
From the last fifty years, ferrites are dominating as magnetic materials over other materials due to some advantages such as high resistivity, wide range of operating frequencies, low loss combined with high permeability, time and temperature stability, versatility of core shapes and low cost.

Pure calcium carbonate, chalk, and coal wastes are taken as starting materials.
Therefore, materials containing quartz and clay minerals can be used in the production of various binding materials and products based on them [12–13].
The building materials industry is one of the largest consumers of energy.
